White, Mayor Nancy Gross, City Ross Klooster, Electric Utility Superintendent Dan Patrick, Power Plant Supervisor Bruce Davison, Davison & Davison Mike Hubbard, Frank Moolin é Associates Brent Stonebraker, Frank Moolin & Associates H. Purdy moved, second by M. Huhndorf that the City continue the Alr Force Electrical Upgrade Project. Mayor White informed the council and public that a decision on the Project had been postponed until further clarification could be obtained. Bruce Davison informed council that if the city chooses not to go ahead with the project, the government has two options. They can terminate the contract on the terms of convenience or they can terminate the contract on default. The termination for convenience means that the government walks away and the city walks away, with neither side paying the other any money. Occasionally the contractor is entitled to recover costs expended. He felt that the government would be very unlikely to compensate the city if this option were chosen. The termination for default involves the government telling the contractor they arc in breach of contract and the government would attempt to recover all the dollar damages caused by this breach. Mr. Davison went on to explain to the council the various areas of possible financial loss the city may face if a termination for default is chosen. Minutes of Special Ci ty Council Meeting April 15, 1989. Page 2 of 3. There was some discussion on the qualifications of Bruce Davison in the area of construction law.

Construction Cash Flow Appendix A = Engine/Generators & Switchgear Transmission Line Poles 1988 Sitework Contract GALENA SYSTEM DESCRIPTION t. General The Clty of Galena is in the process of constructing a small power system to provide electricity and waste heat to the city and provide electrical energy and capacity to the Air Force under a contract for service, The power system will consist of a diesel power plant, bulk petroleum fuel storage facility Including fuel supply lines, a power line to the Air Force power plant and a substation at the Air Force power house. This power plant will be the sole power source for the City of Galena and the Galena Alr Force Station when it is completed in 1990. The City currently sells about 2,422,00 Kwh In the Galena area and its normal peak output is 600 to 6§0 Kw although It peaked near 750 Kw during the record cold winter this year. The Air Force uses some 5,707,000 Kwh and normally peaks near 11@0 Kw. During the same record cold period, this spring, they peaked at 1,380 Kw. The City’s contract abttn Part ener Perey taba tha Ale Cavan uilth a aananitu nf at laset 1 FAN ad Extercec Pege Kw. The Ai rce guarantees they will utilize a mini 1 of 390,000 Kwh per month or 4,680,000 Kwh per year. Part of the power currently generated by the Air Force is used to supply civillan and other governmental agency loads on or near the base. The City anticipates that these loads will be added to the city side of the system when this construction project is finished. The annual non Air Force load Is estimated at 350,000 Kwh. The City currently has a diasel electric power plant which has three generators installed. The generators consist of two 250 Kw and one 500 Kw machines. The electricity is transmitted throughout the Alexander Lake Townsite at 2400 V and at 4160 V in Old Town. The City Is now changing over the entire system to a 4160 V grounded Y system which will be compatible with the generation voltage of the new plant. The existing power piant has waste heat recovery which is provided to the school and other nearby community buildings. The contract with the Air Force created the need for expansion of the Galena power system. The Air Force contract has a series of technical requirements which were instituted to assure the Air Force that the supply of energy will be reliable. These requirements include a minimum plant capacity of 2,883 Kw dedicated to the Alr Force and the ability to supply 1,700 Kw with the largast two units out of service. At the City this translates to a minimum capacity of 3244 Kw to serve the Air force alone. The peak city load brings the needed generation capacity to 3894 Kw. 4 2 7.10.1909 153930 FROM CITY OF GALEKA AK. il, Project Descriptions A General Presented in the Sections that follow will be a description of the planned system. Also included will be a description of what has been constructed and what materials, Supplies and services have been purchased. illustrating system plans are drawings as listed below and inventories of Purchased items shown in the appendix. The drawing titles which are Included are as follows: L1 Project Location Map and Transmission Line C1 Site Plan C2 Fuel Pipeline, Barge Landing C3 Power House Site Plan C4 Power House Floor Plan C5 Power House Section FROM CITY GF GRLENP KK. 7.18.1989 15832 a) Air Force The basic Alr Force Criteria in the contract that established system parameters are outlined in this section, The Alr Force basic requirements were that power would be supplied to the air force from a diedel fueled plant which would meet the following conditions. 0 Be 99.9% raliable;i.e. not be Incapable of delivery power for less than 8.76 hours per year. © Maximum down time of 2 hours In any one period. o Have 1,700 Kw capacity with two largest generators out. o Have load factor no less than 60%; i.e. Install a minimum of 2,833 Kw. © Include a recording disturbance analyzer to assure that the contract voltage and frequancy requirements are met. © Be subject to a $400 penaity each time an outage results In the Alr Force radar dropping off line. © For an outage period, give up a prorated share of the money to be paid by the Air Force for the service. © Provide the service to the Air Force for 20 years following at completion of construction and testing of the system. 0 Provide a Reliablilty, Availability, and Maintainability, (RAM) analysis to prove that the system will meet its requirements. FROM CITY OF GALCNA AK. 72.10.1909 16831 b) City The City’s basic requirements are to construct a power system that would anable the City to provide power to the Air Force and to expand and make more reliable their existing system. To achieve these criteria the City responded to the Air Force RFP ina proposal which was dated May 13, 1987. In this proposal the Clty stated that they would build a system with 4 new diesel generators and the old plant. The new units had been bid by Craig Taylor. The new units would be placed in a power house which would be attached to the old building. The City would also build a tank farm with enough capacity to store all of the fuel oll required by the Air Force and the City. In addition the City would construct a power line to the Air Force Station and connect to the Alr Force's existing switchgear as required in the RFP. Further, the City would construct the generating plant in accordance with the RAM analysis that was included as part of the proposal. c) RAM The RAM analysis prepared for the proposal dealt with the criteria which needed to be built into the system to meet the Air Force requirements. in basic terms the RAM analysis required that no single long term failure could cause the system to be out for more than two hours and that equipment and the operations of the system, would achieve a failure rate well below the 8.76 hour maximum Air Force requirement. FROM CITY OF QALENR AK. 7.10.4909 15832 The basic way of meeting this requirement was to provide at feast one level of redundancy in all critical items. The one exception to this was the power line which was predicated on dedicated equipment and repair parts, and retainage of personnel with the experience and ability to do repair work while the system was energized. As a result of this analysis, the design and construction are proceeding on the basis that many functions will be duplicated. As an example there will be two air receivers to start the engines, two separate connections to the fuel system, two cooling piping loops and two transformers will be supplied for each end of the power line. A total of 6 engines and generators will be used as the engines are the most unreliable portion of the system. Based on the criteria and analysis which has been briefly presented here the project features were selected, and designed and will be constructed as detailed In the narrative and the illustrations which follow. The purpose of the section is to show the reader that the power system being constructed will have special characteristics which wil! enable It to meet the contract requirements. B. Power Piant iSite The site of the power plant and the tank farm as shown on the drawings is located on a remnant filled meander channel of the Yukon River. The site ig just south of the sewage treatment lagoons and east of the city Warm Storage building. The location was chosen as It Is adjacent to all of the & Extenced Page city buildings Ich include; the City Hall, Warm Stor _ Mental Health o Clinic, Health Clinic, Police Station, existing Power Plant, Laundromat, City Garage, and School. As a result all of these structures can be served with waste heat. The site is located on thawed ground which grades from silt at the surface to silty sand hence to gravel at depth. Because of the site elevation It is being filled with clean non frost susceptible gravel from the Yukon River. This grave! was underlain by geofabric which serves as @ filter, to prevent the gravels from mixing with the underlaying materials. The elevation of the fill was brought up to the grades shown on the drawings. The result is that the powerhouse ftioor will be at elevation 134 which Is 3 feet above the 100 year return frequency flood level. The outside walls of the dikes around the Fuel Tanks at the site will be protected by earth and grass to prevent erosion during floods. To complete the powerhouse FROM CITY OF GALENA AK. 7.10.1969 15834 foundation estimated it will require an additional 16,000 cubic yards of gravel. a@) Status A competitive contract was let during the fall of 1988 to strip the top soll off the site, place a geofabric overiay over the site with a minimum of one foot of gravel cover, to place a compacted gravel fill for the pow- erhouse, and a surcharge and fill for the large oil storage tank. Asara sult 18,000 cubic yards of gravel were placed at the powerhouse and the tank. The top 6 feet of fill at the powerhouse was not compacted, nor was the geofabric and one foot of fill placed over the balance of the area that was stripped, due to the cold weather. Settlement rods were in- stalled in the fill and very little settlement was recorded. At this time the geofabric is being placed and the uncompacted fill re- moved from the powerhouse site. The powerhouse will have compacted till added to bring the powerhouse foundation to the grades shown on the drawings. This work which is under way Is being done by city crews. Future work In accordance with the schedule will be to stockpile gravel this fall when the water level In the Yukon recedes and then finish con- struction of the Fue! Tank area dikes and tank areas the summer of 1990. 2 Building The Power House will be a standard stee! framed metal clad insulated type building. 't will be 80 feet long by 50 feet wide. The bullding walls will be 18 feet to the eaves and the roof will be pitched. The bullding Extacces Page metal finish ani of will be warranted for a perlod of 20 ts. The bullding will be aquipped with an overhead door and three personne! doors. The building will be equipped with full load frames on both ends so it can be extended in length, At this Stage the only interior fixtures tn the building will be an enclosure for the elght sections of switchgear. The switchgear enclosure will be wood framed with windows which will be designed to limit noise from the engines. The Interior wil! be designed to allow for the construction of offices, a restroom and storage above the switchgear room. The structure will have sufficient room to hold the five 780 Kw Craig Taylor engine-generators, which have been purchased, and one 450 Kw engine-generator. The 450 is Presently used as a standby plant for Old Town in Galena. The structure wiil be set ona reinforced concrete foundation and slab. The general slab thickness will be eight inches with some additional thickness under the engines themselves. The concrete will be treated to seal and harden the surface so it will not cause dust in the Powerhouse, The concrete will be placed by city force acoount workers as soon as the loading and footing requirements are available trom the building supplier. The building will be equipped with auxiliary equipment which will be needed for the generation of Power. These items include station, power for lights and auxiliary power to motors, a fuel Pumping supply and filtration system, two Starting alr compressors and recelvers, heating system, alr handling systems including ventilators and fans, piping for the engine cooling system and Provision for the addition of a heat exchanger for waste heat recovery. The exhaust silencers and radiators for engine water cooling will be located outside the building. The fides building will alse have roughed In nlumbinn tac et 1 rest room, and, J water. a) Status The powerhouse was bid during the spring of 1989. As a result of cost evaluation it was down sized 20 feet in length, deleting the section to be 10 FROM CITY OF GALENA AK 7210.1989 i507 rie used for the future water treatment plant. The powerhouse building con tract Is now being renegotiated so It can be supplied before the last barge leaves Nenana, about September 1, and erected before the onset af cold weather, Engine-generators have been purchased from Craig Taylor. The equipment that was obtained Is listed in detail in the appendix. The tive basic en- gines are evindor 1,200 RPM Mitsubishi diesels with a prime power rating of 780 Kw and a one hour Standby rating of an additional 10%. This equipment is mounted, along with the generators from Newage, on large steel | beams. These | beams will be mounted on vibration isolators which will be bolted to the floor. Each of the engine-generator sets weights about 26,000 pounds. The Newage generators are highly efficient, reaching levels of 936% or more. The generators are eastly capable of absorbing the full output of the engines as they are rated at 1,000 Kw, The generators are two bear- ing machines which keeps the added weight off of the rear engine bearing and makes it easier to remove and replace a generator. The generators were selected to operate at 4160 V because this allows direct feed to the town without the added losses and expense of transformers. A smaller engine generator, which was purchased for use at Old Town, is rated at 450 Kw and is already in Galena. This set which has only a few hours on It will have the generator replaced so it will operate at 4160 V. This 1,800 RPM set will be used to operate during the time period when the system needs less than 450 Kw over the amount capable of being pro vidad bv the laraar machines. As this is the only electric start machine on EH. wees, bs Extencas Pega 10. it will also | sed for biack starts to get the syste” line if the air receivers are discharged. a) Status The machines have been manufactured, tested in Renton, Washington, and shipped to Alaska. They are now In storage in Anchorage awaiting ship- ment to Galena. The tests were observed by representatives from the City and Stone & Webster Engineering Corporation. 4. Switchgear Switchgear was furnished along with the engine-generator sets by Craig Taylor. The switchgear is § Kv class. There are eight sections of gear to be located at the City power plant, operating at 4160 volts, and one sec- tion of gear at the Air Force power plant, operating at 2400 volts. The switch gear is equipped with breakers, alarms, synchroscope, synchro- check relays, protective relays, meters and a programmable logic control ler, (PLC), at the City end. The PLC Is programmed to automatically start and synchronize engines and connect them to the buss In accordance with the load demands. ine system is also programmed to shed Wis Cily load in the event of a lack of power. At the Alr Force end is switchgear which enables the Alr Force to syn- chronize their power plant to the City's plant. This synchronizing will all be done manually. This switchgear Is equipped with a breaker, protective relays, meters, synchroscope, and recording disturbance analyzer. a) Status The switchgear was assembled and tested in Renton, Washington along 1 Extances Pasa 15.2 with the units **4 was also shipped to Anchorage and awaits turther snip- ment to Galena. 13 Cf. Tank Farm The city proposed to utilize arctic grade diesel in their bid for the Air Force contract and to provide a tank farm with sufficient storage to assure the Air Force their needs would be met. The city will install a 500,000 gallon steel tank, constructed to AP! 650 standards, of arctic grade steels. In addition, the clty has acquired two 65,000 gallon horizontal tanks. These tanks were cieaned and tested for metal thickness and are in excellent condition. The city intends to install these tanks as part of this project. One 65,000 gallon tank will be used as an operational tank. The second will store Number 1 diesel for emergency use. The 500,000 gallon tank will be equipped with heating colis and a means to circulate warmed oll so the engines can continue to operate when the temperature reaches the extremes it did in the winter of 1988. The fuel lines will be Insulated and heat traced. The tanks will be located in a lined diked enclosure. The dike helghts will be at elevation 133 ‘ which is two feet above the 100 year flood level. The enclosure will be designed in accordance with fire codes and will be equipped with drains. All piping within the diked area will be steel. 1_Status The 65,000 gallon tanks are onsite. A 500,000 gallon tank and fuel piping specification has been written and is ready for bid. 14 7.18.1989 15841 FROM CITY OF GRLENA AK. D2 Fuel Ling The tanks require a fuel line from the river to enable them to be filled. The tine has to have enough capacity to insure timely filling of the tanks. There are additional costs for delaying a fuel barge which will be the means of shipment. Most fue! comes from Nenana at this time. Doiphins will be constructed for mooring the barges. The fuel line which will run from the tank farm to the river will either be 6 inch steel or polyethlylene Pipe. It will be buried about three feet under the ground and run through a conduit under the existing road. {f it is determined that steel is the most Suitable material, it will have a corrosion protective coating. It is likely that this line will be Installed by the city. The line could also be bid as Part of the tank erection package. The line has been designed and Is included as an alternate with the tank farm specification. ET 5 , The transmission line will be built to high standards with no service lines from it. As discussed earlier the line is the single link over which the power will flow to the Air Force. The line will have three conductors and will operate at 23 Kv. The line is relatively short, with a total length of about 2.8 miles in several sections. From the city power plant there will be 502 teet of line to the Antoski double circuit section. This section which is 1,200 feet long and is already constructed, terminates at the intersectlon of Anmtoski and Campicn Roads. From this point it is 12,850 feet to the Air Force power Plant. 15 1_Route. The route is shown on drawing L1. The route, after leaving the Antoski double circuit, follows Campion Road and parallels a bicycle/ snow machine trall which was built along the abandoned Campion pole fine. To pass through the airport area, the route follows the south edge of the north dike until reaching property the Air Force has leased from the Alaska Department of Transportation and Public Facilities (DOT/PF). _—__£. Extaccas Page 1i.} Most of the rig f way questions have already been res id as a result of extensive negotiations with DOT/PF and the local Native corporation Gana a Yoo, Limited. Desion The basic parameters for design of the transmission {Ine have bean calculated and determined. The 23 Kv class line will be designed and constructed In accordance with the NESC Class B standards. The Structures will be wood pole and will generally conform to REA standards for 14.4/24.9 class construction. The conductor size will be 1/0 ACSR and the spans will range from 250 to 300 feet, with the exception of the Antoski section which will be above city IInes in a double circuit configuration. . Line staking awalts final resolution of one remaining ROW Issue which should be resolved shortly. Substations The two 23 Kv substations, one located at the power house and one at the Alr Force Base each will be equipped with two low loss transformers. 16 Either transformer wiil be capable of carrying the full contracted load. The substations will be equipped with air switches and cable elbows so each transformer can be rapidly isolated if it is necessary. The transformers will be specified so that the losses will be evaluated In their design. Each of the transformers will have the low side, 4160 volts at Galena and 2400 volts at the Alr Force base, connected with cables and load break elbows. The cables will go In conduit to thelr respective switchgear. Extra cables will be pulled into each of the two condults at each end, The high side, 23 Kv, will be comprised of tank mounted bushings. The transformers and take off structure will be located within a chain link, barbed wire topped, enclosure. 4, Status. The route has been selected and has the rights-of-way resolved, with the exception of one, as stated earlier. Basic design parameters are set. The transformer specification Is completed and ready for bid. The city has constructed a new double circuit link along Antoskl Drive. The city has purchased and has poles for much of the line on site. The city has purchased'and has two bucket trucks on site, one of which is equipped with , an auger fo- ““'lling and setting screw anchors. Eyessued fags 1)? E. Aire C : The Air Force connection will be via two complete sets of cables in two conduits through their building, over the top of thelr switchgear, to the city's add on section of switch gear. This will be equipped with a breaker, meters, synchroscope and recording distrubance analyzer all as required in the contract. The switchgear is designed to use the same breakers as the gear at the city so only one spare breaker will be required. ‘Stone é Webster Enginesring Corporation July 3, 1989 SCHEDULE GALENA ELECTRICAL UPGRADE PROJECT City Of Galena Alaska FROM CITY OF GALENA AK. polarconsul, ~——~na Power Project GALENA POWER PROJECT ESTIMATS 80’ x 50’ Bldg & (1) 500,000 gal.

PRINCIPLES OF OPERATION AND MAINTENANCE 1.1 GENERAL The hot coolant from the diesel engines is led through a coolant manifold placed in front of the engines to a flat plate heat exchanger. After passing through the heat exchanger, the coolant is led to the radiators for further cooling if needed and from there back to the engines. The other fluid which passes through the heat exchanger is heated to a temperature which is only 5 degrees cooler than the outlet temperature from the engines. After being heated, this fluid is pumped through insulated steel pipes to the High School, the new Elementary School, the Old Garage, the Water Treatment Plant, and to the Clinic. In these buildings (Except the Clinic) the hot fluid passes through another flat plate heat exchanger, in which heat is transferred to the boiler return water, again without mixing the two fluids. After giving off heat to the boiler return water, the fluid is returned to the Power Plant, where it again is led through a circulating pump and finally to the flat plate heat exchanger. The system is slightly different in the Clinic; here the fluid is pumped directly into the boiler return line and circulated through the Clinic heating system. In order to avoid excessive pressures in the Clinic heating system, a pressure reducing valve is inserted in the line to the Clinic. This valve is located in the Power Plant. A unit heater is placed in the Southeast corner of the High School crawl space. This unit is controlled by a separat thermostat and uses the fluid returning to the Power Plant for providing heat in that corner of the crawlspace. 1.2a THE POWER PLANT COOLING SYSTEM The Power Plant cooling system consists of a manifolding system, three radiators with separate controls, and an AMOT valve. All three engines pump hot coolant into the upper manifold through a check valve. The check valves have been provided with a small leak hole, which allows hot coolant to circulate slowly backwards through engines, that are not running, thereby keeping those engines warm and ready for immediate start up when needed. Generator #3 is equipped with an exhaust gas boiler, which cools the exhaust gasses down to 350-400 degrees F. and heats the coolant coming from the engine before it is pumped into the top manifold. ~ After passing through the heat exchanger, the coolant is led either directly to an AMOT valve or to the radiators, from where it then is led to the AMOT valve. An AMOT valve is a thermostatically controlled mixing valve, which mixes the coolant returning directly from the heat exchanger with the coolant returning from the radiators to obtain a temperature of 180 degrees fahrenheit. Under normal conditions the temperature of the coolant coming from the heat exchanger will be 180 degrees or lower and thus very little flow goes through the radiators. During periods with a limited heating demand, the temperature of the coolant from the heat exchanger will be higher and a part of the flow will be directed through the radiators. At a temperature of approximately 185 degrees fahrenheit, all of the coolant will be directed through the radiators. When the temperature in the lower manifold reaches 185 degrees fahrenheit, the radiator fans are intended to cycle in order to maintain this temperature. In order to limit the amount of power consumed by the radiator fans, the thermostatic switches located on the lower manifold in front of engine #1 should cycle in the following order: 1. Radiator #3 on low speed 2. Radiator #1 on low speed 3. Radiator #3 on high speed 4. Radiator #1 on high speed 5. Radiator #2 on high speed. (This is a single speed motor only) All three radiators are to be included in the cooling circuit at all times. Due to their different internal flow resistances, the flow will be divided between the radiators approximately as follows: Radiator #1: 2/7 of the flow Radiator #2: 2/7 of the flow Radiator #3: 3/7 of the flow These values are almost proportional to the cooling capacities of the radiators and thus no regulation of the flow is necessary. The expansion tanks located at the top of the radiators will normally be completely flooded. Thermal expansion of the coolant will be compensated for in the expansion tank located in front of engine #1. This tank should be approximately 3/4 full when the system is hot. 1/4" copper vent lines are connecting the radiators, the engines, and the exhaust gas boiler to the expansion tank in order to remove air that may have been trapped in these locations. The valves on these lines should be kept open at all times. 1.2b. THE POWER PLANT WASTE HEAT SYSTEM The waste heat system in the Power Plant consists of a heat. N exchanger, 2 pumps, a thermostatic valve (AMOT), and an expansion tank. Under normal operation fluid (50% ethylene glycol and 50% water) will return from the user buildings to the Power Plant at approximately 160-170 degrees fahrenheit. After passing through one of the two pumps, the fluid will pass through a y-strainer and into the heat exchanger, where it will be heated to at least 178 degrees fahrenheit. The temperature is controlled by the AMOT valve located on the outlet of the heat exchanger on the east wall of the Power Plant. This AMOT valve operates as follows: When the temperature of the fluid coming out of the heat exchanger is below 175 degrees, the entry port (A) is open to port B. However, port B is blocked with a blind flange and thus flow through the valve is stopped. In order to allow a small amount of fluid to pass through the valve for measuring purposes, a small hole (1/4") has been drilled between port A and port C. Thus, when the temperature is below 175 degrees, only a trickle is passing through this valve. Once the temperature increases above 175 degrees, the AMOT valve slowly opens between ports A and C, thereby letting fluid coming from the heat exchanger continue out into the waste heat system. Since the amount of heat available from the engines is limited, only a certain amount of fluid can be heated from the initial 160-170 degrees to 180 degrees. By limiting the flow through itself, the AMOT valve keeps the outgoing temperature at or above a 178 degrees F. 1.2c THE POWER PLANT, ROUTINE MAINTENANCE Every day: l. Check that one pump is operating by noticing if there is a pressure differential over the pumps. This differential should normally be more than 10 PSI. If no pressure differential is shown check to following: Does pump operate? Valves in right position? Fluid in system? (Check pressure) Pressure gauge petcocks closed? 2. Check the pressure on the pressure gauge adjacent to the connection to the expansion tank. With one pump operating this pressure should be 15-17 PSI. If pressure is lower, add fluid to the system. USE A 50/50 MIXTURE OF WATER AND DOWTHERM SR-1 ONLY. DO NOT USE AUTOMOTIVE ANTIFREEZE SUCH AS PRESTONE, SHELLZONE ETC. If the system keeps loosing prressure, check the entire system for leaks and repair as necessary. Under normal conditions this system should loose very little fluid. 3. Check the coolant level in the expansion tank in front of engine #1. The tank should be approximately 3/4 full. If less than 3/4 full, add a 50/50 mixture of water and antifreeze such as Prestone, Shellzone etc. Check that the valve on the over flow line located on the upper rear connection on the expansion tank is closed. (Temperatures in the exhaust gas boiler's first stage may cause boiling if the system is not under slight pressure.) 4. Check the temperature of the return line to the engines on the thermometer located in front of engine #1. This temperature should not be above 190 degrees. if it is: Are radiators operating? Are radiators plugged with dust? Is there sufficient coolant in system? Check valve positions. Check thermometer adjustment If it is still not possible to reduce return temperature below 190 degrees: Open by-pass valve around the AMOT valve. If this reduces temperature, dismantle AMOT valve and replace thermostats. 5. Check the coolant temperature on each engine in operation. This temperature should not be above 200 degrees. If it is: Check thermometer adjustment. Check valve positions. Check temperature on upper manifold thermometer located between engines nos. 1 and 2. Every Month: 1. Operate each radiator fan motor for 1/2 hour on manual override to prevent bearing seizure and moisture collection in the motor. 2. Check all piping for leaks. 3 Open the inspection doors on the heat recovery boiler and check that the finned tubes are not plugged with soot. If they are, clean the finns using a vacuum cleaner and/or a stiff brush. Every year: l. Lubricate bearing on stand by pump. 2. Have a sample of the coolant and a sample of the waste heat recapture loop tested in a laboratory. (Van Waters and Rogers, Anchorage, phone 272 9507) 3. Clean the strainer on the waste heat recapture loop. This strainer is located adjacent to the heat exchanger. 4. Stop the pumps, and drain enough fluid out of the waste heat recapture loop that the pressure gauge adjacent to the expansion tank connection reads 0 PSI. Check the air pressure in the expansion tank adjacent to engine #3 with a tire gauge. The pressure should be 12-15 PSI. 5. Check the condition of the hose sections between the coolant manifold and the engines and generators. Replace if not in good condition. 6. Check the radiators and clean the exterior surfaces of the core if necessary. 7. Open the inspection doors on the exhaust gas boiler and clean the finns using a vacuum cleaner and/or a brush. 1.3 THE ARCTIC PIPE. l1.3a. Routine Maintenance. The arctic pipe (manufactured by Brown Boveri Corporation, 1460 Livingston Avenue, North Brunswick, N.J. Phone 201 359 4002) does not require any maintenance except for periodic inspections as follows: Every month: 1. Visually inspect the line for leaks and exterior damage from vandalism etc. Make sure that all hangers and pipe anchors are in place and that all half shells are in place over joints. Repair exterior damage to the High Density Polyethylene jacket pipe with sheet metal jackets in place with hose clamps until a permanent repair can be made with "“wedge-joint" half shells identical to the half shells used over joints on this pipe. 1.4 THE CLINIC. 1.4a. GENERAL The hot waste heat fluid from the power plant is pumped directly into the boiler return line and circulated through the boiler and uw out through the Clinic heating system. After returning from the heating system the fluid is returned to the power plant through the 2" AMOT valve located in the storage room adjacent to the boiler room. This valve contains 160 degree elements and is installed so as to limit the outgoing flow, if the return temperature of the fluid exceeds 160 degrees F. Due to the Operating band of the valve elements, the outgoing temperature can be as high as 166 degrees. 1.4b. ROUTINE MAINTENANCE Every month: Check the system for leaks. Check that the expansion tank is not completely filled with fluid. Activate the oil fired boiler for 1 minute using the temperature controls. Check that the high temperature limit on the boiler controls is set below 180 degrees. Recommended setting: 150-160 degrees. The low temperature limit should be set at 140-150 degrees. 1.5 THE WASHETERIA 1.5a. GENERAL The hot waste heat fluid from the power plant is pumped through a flat plate heat exchanger and is returned to the power plant through the 3" AMOT valve located adjacent to the heat exchanger. This valve contains 165 degree elements and is installed so as to limit the outgoing flow, if the return temperature of the fluid exceeds 165 degrees. Due to the operating band of the valve elements, the outgoing temperature can be as high as 171 degrees. 1.5b. ROUTINE MAINTENANCE Every month: Check the system for leaks. Activate the oil fired boilers for 1 minute using the temperature controls. Check that the high temperature limit on the boiler controls is set below 180 degrees. Recommended setting: 150-160 degrees. The low temperature limit should be set at 140-150 degrees. Check that the circulating pump located above the heat exchanger is operating. 1.6. THE OLD GARAGE 1.6a. GENERAL The hot waste heat fluid from the power plant is pumped through a flat plate heat exchanger located outside the boiler room. After passing through the heat exchanger, the fluid passes through a thermostatic Danfoss valve, which is controlled by a = sensor located in the line feeding into the boiler. By turning the knob on this valve to increasing numbers, the temperature in the boiler return line is increased. This temperature should be set at approximately 175 degrees. 1.6b. ROUTINE MAINTENANCE. Every month: Check the system for leaks. Activate the oil fired boiler for 1 minute using the temperature controls. Check that the high temperature limit on the boiler controls is set below 180 degrees. Recommended setting: 150-160 degrees. The low temperature limit should be set at 140-150 degrees. 1.7 THE NEW SCHOOL 1.7a. GENERAL The hot waste heat fluid from the power plant is pumped through a flat plate heat exchanger located in the boiler room. After passing though the heat exchanger, the fluid passes through a thermostatic Danfoss valve, which is controlled by a = sensor located in the line feeding into the boiler. By turning the knob on this valve to increasing numbers, the temperature in the boiler return line is increased. This temperature should be set at approximately 175 degrees. In case of a leak in the New School, the shut-off valves located underneath the New School adjacent to the district heating lines can be used to isolate the New School from the waste heat system. 1.7b. ROUTINE MAINTENANCE. Every month: Check the system for leaks. Activate the oil fired boilers for 1 minute using the temperature controls. Check that the high temperature limit on the boiler controls is set below 180 degrees. Recommended setting: 165 degrees. The low temperature limit should be set at 160 degrees. 1.8 THE SCHOOL The the waste heat supply and return lines enter the School crawl space adjacent to the the utilidor connection and run in the crawl space to the boiler room. The hot waste heat fluid from the power plant is pumped through a flat plate heat exchanger located in the boiler room. After passing through the heat exchanger, the fluid passes through a thermostatic Danfoss valve, which is controlled by a sensor located in the line feeding into the boiler. By turning the knob on this valve to increasing numbers, the temperature in the boiler return line is increased. This temperature should be set at approximately 175 degrees. A small circulating pump and a unit heater is mounted on the return. line in the crawl space, adjacent to the utilidor connection. The pump and the unit heater are controlled by a line voltage thermostat mounted adjacent to the unit heater... This thermostat should be set 5 degrees above the temperature desired in the crawl space. A small heat exchanger is mounted adjacent to the pump. manifold in the boiler room. This heat exchanger transfers heat from the boiler system to the hot water system. The temperature is controlled with a thermostatic Danfoss valve located adjacent to the heat exchanger. Hot water temperature is increased by turning the control knob to a higher number. 1.8b. ROUTINE MAINTENANCE. Every month: Check the system for leaks. Check that the circulating pump located adjacent to the heat exchanger is operating. (During the summer months this pump) can be used to circulate the entire heating system in the school. Flows will be reduced but adequate at low heating loads.) Activate the oil fired boilers for 1 minute using the temperature controls. Check that the high temperature limit on the boiler controls is set below 180 degrees. Recommended setting: 165 degrees. The low temperature limit should be set at 160 degrees. Check that the pump and the unit heater in the crawl space are operating by changing the thermostat setting. If the unit heater gives off heat, the pump is operating as intended. Check that the unit heater/pump thermostat is set 5 degrees above the desired temperature in the crawl space. Alaska Power Authority contact: Peter N. Hansen, phone (907) 261 7221.
