March 5, 1993 State of Alaska Walter J. nickel, Governor Alaska Energy Authority A Public Corporation RECEIVED SEP z 3 2008 Robert Dryden, P.E. Aleutians East Borough Power & Control Engineering P.O. Box 231929 Anchorage, AK 99523 Re: Cold Bay Waste Heat Recovery Preliminary Design and Cost Estimate Dear Mr. Dryden: Enclosed please find a copy of the Cold Bay Waste Heat Recovery Report and Concept Design prepared by Frank Moolin and Associates on February 12, 1991. As discussed in our previous telephone conversations, the Energy Authority is interested in having a. revised design and cost estimate prepared based on a more refined project scope with the goal of developing a package that can be readily financed. Please provide a proposal for engineering services including a scope of work and estimate of fees based on the following project scope and criteria: PROJECT SCOPE Perform field investigation and gather sufficient field data to allow preparation of final construction documents should project advance to that stage, Field survey will need to include investigation of routing options for distribution piping. including easement issues, soils conditions (based on local knowledge -not geotechnical investigation), and potential conflicts with existing utilities and facilities. 2. Prepare design drawings in sufficient detail to allow preparation of an accurate cost estimate (approximately 35% to 50% design documents). Documents to include at a minimum a site plan; floor plans of power plant and end -user buildings; system schematic; and preliminary selection of heat exchangers, unit heaters, pumps, expansion tank, and miscellaneous devices. 3. Prepare a detailed -construction cost estimate with a breakdown of materials, freight, and labor. The Energy Authority can provide current unit costs for arctic pipe, energy meters, and other devices. Cost estimate to be based on force -account construction by G&K Inc. staff in the fail of 1993. SYSTEM CRITERIA 1. The system will serve the 3 State DOT facilities and the FAA shop which are closest to the power plant ( scenario #1 in Moolin Study). P.O. Box 190869 701 East Tudor Road Anchorage, Alaska 99519-0869 (907) 561-7877 Fax; (907) 561-8584 2. The FAA facility will receive waste heat via a heat exchanger connected into the existing hydronic system. The 3 DOT facilities will receive waste heat via new hydronic unit heaters. 3. The existing power plant heat exchanger will be evaluated and, if deemed adequate, used for the new system. If the heat exchanger is determined to be inadequate for serving the new and existing waste heat recovery system, a new heat exchanger will be selected (preferably a shell and tube model). 4. Arctic piping for the distribution will be a pre -insulated piping system with a welded steel carrier pipe, polyurethane insulation, and an HDPE outer jacket (I.C. Moller or equivalent). 5. Heat delivered to end user buildings will be measured with magnetic -style energy meters (Clorius or equivalent). 6. The prevailing design philosophy will be to keep the system simple from both a construction and an operation standpoint. If you have any questions please contact me or Steve Stassel at 561-7877. ,.

Calculations 2. Cost Estimates 3. Raw Data SECTION 1 COLD BAY 'WASTE PEAT RECOVE-n r REPORT A`!C CotiCEPT �z T!—j 0 -XEt u IVE SUMMARY .4 potential for waste heat recovery exists in the community of Cold Bay. Cold Bay is a community of approximately 150 people, located 40 miles from the western tip of the Alaska Peninsula, 630 air miles from Anchorage, and 180 air miles from Unalaska. The waste heat from the coolant of the diesel engine -generator set owned and operated by G&K, Inc., could be recovered and circulated to heat buildings in the community. A waste heat recovery system can provide enough heat to heat virtually all of the publicly owned buildings in the general vicinity of the power house and several publicly owned and private commercial buildings further from the power house as well. However, these buildings are spread out and can not be served on an equal cost basis. Also, varying ownership and planned future use of the buildings makes some buildings more attractive for providing waste heat to. Therefore, policy makers will have to choose between alternatives. Several scenarios have been evaluated and are presented here. Scenario #1 provides waste heat to the four (4) public buildings nearest the power house. This includes the FAA shop, State Department of Transportation / Public Facilities (DOT/PF) shop, State DOT/PF warm storage, and the future State DOT/PF warm sand storage to be constructed summer 1990. Estimated Project Cost Total Fuel Oil Savings 25,900 Gallons Total Annual Fuel Cost Savings S 28,500 (0&M Cost S 7,600) Scenario #2 includes the buildings in Scenario T1 and extends a heating loop to the north to serve the city building and the U.S. Fish & Wildlife complex. This complex includes the main office/shop/storage building, the bunkhouse, and four (4) separate housing buildings. This scenario would be an expansion of Scenario #I, Values below are inclusive of Scenario �1 values. A further revision would be to just include the city building if Fish and Wildlife declines to participate. Estimated Project Cost 51,271,053 Total Fuel Oil Savings 35,900 Gallons Total Annual Fuel Cost Savings S 39,500 (O&M Cost S 13,700) Scenario �3 includes the buildings in Scenario #1 and extends a heating loop to the south to serve the Cold Bay school. This scenario would be an expansion of Scenario 1. Values below are inclusive of Scenario -1 values Estimated Project Cost Total Fuel Oil Savings Total Annual Fuel Cost Savings (00 Cost COLD BAY W SIIT7�L 7E,�T `.c-0 V7 R.EPORI -IIJil 5777,021 31,700 Gallons S 34,000 5 11,700) Scenario #4 includes all of the buildings listed above (essentially it is Scenario #1 expanded to the north to include the additional Scenario #2 buildings and to the south to include the additional Scenario #3 building). Estimated Project Cost $1,614,728 Total Fuel Oil Savings 41,400 Gallons Total Annual Fuel Cost Savings $ 45,500 (0&M Cost S 16,800) Scenario #4a is identical to Scenario #4 with distribution main pipe sizes increased to allow for future expansion to the south. Annual fuel and dollar savings are identical. Estimated Project Cost $1,788,642 Scenario #5 expands the system further by extending a heating loop south past the school to serve the clinic, the airport buildings and buildings in between. This is the longest piping run considered. Besides the clinic, it would serve the State DOT/PF fire station, FAA flight service, FAA water plant, Post Office, Reeve Airlines complex (2 buildings), and Pavlof Services complex (2 buildings). There is not enough waste heat to serve Scenario #5 Scenario #5 is considered a low probability for waste heat recovery due to high construction costs, piping heat losses, complexity and uncertain future of some of these users. Scenario #5 is presented here only to the extent required to identify its potential for possible future expansion. No cost estimate was performed for Scenario #5. A possible 6th scenario would extend a branch from the scenario #5 loop to serve eighteen (18) FAA and DOT/ PF buildings consisting of 10 single housing units and 8 duplex housing units. This study did not analyze providing waste heat to the housing units. Decision Criteria Economic and public policy decisions wiil consider some or all of the following factors: 1 1.1. Proximity and piping loops. The cost of runni ne the waste heat eC _ 2, the individual heat exchangers may Take the pay back L,e, ;od t-D.C. COLD BAY WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN FEERUARY 12, _=g: ' client. This factor may limit this project to the buildings in the immediate area of the power plant. If this consideration is overriding, the FAA shop and the DOT/PF's shop, warm storage building, and new warm sand storage facility will be the highest priority users. If other users are considered, the grouping of facilities on a piping loop will become a significant factor. The City Building is approximately half way to the U.S. Fish and Wildlife site, but the school and clinic are in a different direction. Waste heat piping to the clinic would open up the possibility of providing waste heat to the State DOT/PF fire station, FAA flight service, FAA operated water plant, Post Office, Reeve Aleution complex, and Pavlof Services complex, and other private users adjacent to the runway. Subject to the above decisions, FAA and D.OT/PF family housing units could be waste heat users, but it would require another long loop on the waste heat piping layout and multiple exchangers in the housing hot air furnaces. 1.1.2 Potential Long Term Users and Expansion. At the time of this report (March 1990), the FAA and National Weather Service (which shares the .FAA flight service building) plan to significantly reduce their respective staffs over the next four years. Certainly decisions about capital investments in waste heat must consider this planned reduction. U.S. Fish and Wildlife appears to have a long term commitment to Cold Bay and the Izembek National Wildlife Refuge. This fact, combined with the proximity to the power house, should make Fish and Wildlife a prime candidate for waste heat use. Federal decision making may make utilization difficult, as will the difficulty of hooking up waste heat to six relatively small buildings. The DOT/PF Shop and Storage Facilities will be utilized as long as DOT/PF is responsible for the maintenance of the airport. there are no current plans to close the airport. The state shop, warm storage, and warm sand storage are excellent candidates for waste heat recovery because of their proximity to the power station. The Mayor and City Council are negotiating with the Trawlers Association to make Cold Bay a center for fishing crew changes. This would increase local seasonal air traffic and increase the possibility for the continuing or even the expansion of Cold Bay as an airport. Also. the air carriers in Cold Bay expect to be in business for an indefinite period, and with expanding guiding/tourist activity in the area, air COLD BAY WASTE HEAT RECOVERY REPORT AND CONCEPT DES:G1N FEERbARY 12. 1991 traffic could increase. Private potential waste heat users such as Reeve and Pavlof Services (which is operated by Reeve) and others around the airport are interested in any savings in heating costs. This potential for stability and even growth makes providing waste heat to the airport area attractive. The Post Office has a new building and will be in Cold Bay indefinitely. If the installation costs have a reasonable payback, the Post Office is a potential customer. The State Hatchery at Russell Creek is under utilized, and its future will have a small effect on air traffic at Cold Bay but because of distance, no effect on waste heat recovery unless the extra hatchery staff were housed in Cold Bay proper. 1.1.3 Community Desires/State Priorities The Mayor and City Council members, that were interviewed, indicated a strong preference for using waste heat in the city building (community center) and medical clinic. A major portion of this interest has to do with a limited city budget and significant fuel' bills. They were supportive of using waste heat at the school. A summary of the construction cost estimates along with design and SIGH costs is included in the Cost Estimate Appendix for each alternative and scenario. The local DOT/PF and FAA Personnel were generally supportive of utilizing waste heat in order to save operating cost and lower maintenance cost. The ultimate decision will probably be made at a higher administrative level based on 1st cost and operating cost reduction. SECTION 2 COLD BAY WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN FEBRUARY 12, ical 2 0 INTRODUCTION 2.1 Objective The objective of the field investigation and report is to ascertain the viability of waste heat recovery use in the community of Cold Bay. It has been established that there ;s a potential source and use for the heat energy, and that the community is interested in pursuing this project. 2.2 Methodology The investigation and analysis were approached as follows: Pre -site Visit: Information collection consisted of telephone contact with community officials, owners/operators of potential user buildings, power plant operators, and gathering land use/ownership information. Field Investigation: Coordination with the G&K power utility owner/operator, building owner/operators and local elected officials was performed. Photographs were taken of the potential user buildings as well as the boiler/furnace equipment. The power plant was photographed and sketches were made of the coolant piping connections. Available fuel costs and heating `s records were obtained from each interested potential recipient of waste heat. Office Analysis: Additional information regarding weather and historical trends were collected. Calculations were performed to fill in missing fuel use data for several of the potential users. This information was used to produce a model to predict the system performance and the amount of energy recovered. 4. Report Preparation: A draft report was prepared for the prospective clients prior to final report preparation to ascertain the correctness of the assumptions made and obtain approval of the approach taken. 2.3 Community Description Cold Bay is a community of approximately 150 people 40 miles from the western end of the Alaskan Peninsula. The community centers around the Airport with FAA, National Weather Service, State of Alaska Department of Transportation and Public Facilities (DOT/PF), and ancillary staff. A smaller population of U.S. Fish and Wildlife staff work at the nearby Izembek National Wildlife Refuge and State of Alaska Department of Fish and Game staff work at the Russell Creek Hatche>-v. 1r . addition, several airlines and charter compar;ies ^aye D'2 COLD BAY WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN FEBRU4RY 12 1991 f resident staffs and there is a school post office, community center, medical clinic, store, hotel, restaurant, and bar. The land is flat and rolling. Diesel fuel cost at Cold Bay were $1.18 in February 1990 and were scheduled to fall to S1.10 on March 1. Diesel is used for heat and power generation. 2.4 Applicable Codes and -Regulations The most recently State of Alaska adopted editions (1985 for all except as noted) of the following codes and regulations have been used in the preparation of the concept design. These are listed below: Uniform Plumbing Code (UPC-1979) Uniform Mechanical Code (UMC) Uniform Building Code (UBC) Uniform Fire Code (UFC) National Electrical Code (NEC-1990 - Pending adoption) National Fire Protection Association (NFPA) SECTION 3 COLD BAY WASTE HEAT RECOVER`, REPORT AND CONCEPT DES?1'�-�1 � FEBRUARY 12. .^91 3.0 DESCRIPTION OF SITE VISIT Two engineers from Frank Moolin & Associates, Inc. visited Cold Bay from January 31 to February 2, 1990.

Power is generated by three (3) Catapillar generators rated for continuous load as follows: 1-Model 3512 - 650 Kw I -Model 3512 - 845 Kw 1-Model 3512 - 650 Kw These engines are utilizing the same block, and have different configurations and turbos. thegenerators use number 2 fuel oil year round. Cooling for generators is provided by external horizontal radiators with automatic controls. Piping is uninsulated, resulting in large heat loss to the building. The plant is piped for waste heat recovery with a Young RC-1616-TC-1P shell and tube heat exchanger. A waste heat manifold is installed and waste heat is being used to heat the power plant, the switch gear/office building and the new office shop building. The heating load for ancillary structures was calculated and deducted from the total waste heat available because these structures are scheduled to be torn down. The other wooden structures on site will be.torn down. Under present conditions, one generator is able to maintain the village load and the other two are kept on warm stand-by using return coolant from the radiators. At the time of this report (March 1990), the Cold Bay Power Plant is negotiating with Mark Air to provide power to an expanded Mark Air facility in Cold Bay. This expanded load will increase the amount waste heat available in the future. 4-2 Floor Plan and Schematics See the Figures 3 and 4 for a simple floor plan and schematic of the system (located in Section 7). 4.3 Photographs See the attached copies of the original color photographs of the power plant and coolant piping. 4-4 Load information Attached Table I contains the utility 'oad data -or I988 and .989.

Virtually all of the land is owned by the State of Alaska and leased to the other users. The exceptions to this are the U.S. Fish and Wildlife property and several small private holdings. Proposed routing for the heat pipes will be along the existing road systems for the most part. The new powerlines were buried along the road system when they were installed several years ago. Running the heat lines along the same routes would take advantage of existing informal easements and current knowledge of existing buried utility locations. The powerlines were reported to be buried to a depth of three feet or less. The waste heat liens should be buried parrallel to and deeper than the power lines to get below the frost. The routings shown on the pipe routing plan deviate from the formal road boundaries shown as the existing roads do not follow them in many places, and the actual routing should follow the existing roads/power line easement. There are paved road surfaces at the F&W property. To prevent trenching across the pavement and not being able to cost effectively repair it, the heat pipes were routed behind the 4" buildings. 'Cu.

G-, SECTION 7 COLD BAY WASTE HEAT RECOVERY REPORT AND C�"aCc0T E_ c iGN 7.0 CONCEPT DESIGN ` 7.1 System Narrative A large number of scenarios are poss'ble for the distribution of the waste heat from' the power plant. The resulting system will have to take political, economic and future outlook factors into account. Four scenarios have been developed as the most probable. The Pipe Routing Site Plan shows pipe routing to all of the buildings in the Scenarios #1 - 14, but only that piping which is required to service the buildings selected will actually be constructed. 7.1.1 Scenario #1: Served buildings include: FAA SHOP DOT/ PF SHOP DOT/PF WARM STORAGE DOT/PF WARM SAND STORAGE This scenario is based on supplying the closest buildings to the power plant. This will reduce the cost by minimizing the required piping and provide for the fastest system payback. 7.1.2 Scenario #2: Served buildings include: FAA SHOP DOT/PF SHOP ". DOT/PF WARM STORAGE DOT/PF WARM SAND STORAGE CITY BUILDING U.S. FISH & WILDLIFE MAIN OFFICE/SHOP/STORAGE U.S. FISH & WILDLIFE BUNKHOUSE AND HOUSING (4 BUILDINGS) This scenario was developed around long range commitment considerations. The system schematic shows the city building and the Fish and Wildlife buildings on the system. Both the Fish and Wildlife complex and city building have a long range commitment to the city and capable of a long term payback is required. 7.1.3 Scenario #3: Served buildings include: FAA SHOP DOT/PF SHOP DOT/PF WARM STORAGE DOT/PF WARM SAND STORAGE COLD BAY SCHOOL This scenario simply shows the school added to the basic system. The school could be the primary target for the waste heat because of its proximity, long term commitment to the community and the vaiume of fuel consumed. . Fr^ I__01. COLD SAY WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN FL:MARY :2. j991 ' 7 I.4 Scenario =4: Served buildings including all of those listed above.

There is currently not enough waste heat to serve scenario #5. This scenario is for the group of buildings that are located the farthest from the power plant. Running lines to. ihese buildings will be the most costly, but if service to one of them is required, it would be more economical to service as many of the others shown in the Site Plan as possible. 2 Primary and Secondary Piping Jacket water piping will be valved to recover heat from whichever 3512 gen-set is on line. The exisiting power plant heat exchanger will be utilized for expanded waste heat recovery. The in -plant cooling piping will not be altered and the existing waste heat recovery will not be changed. The power plant owner/operator is agreeable to increase waste heat recover subject to negotiated contracts. Unlike other heat exchangers, which will be flat plate type, the current existing installation includes one shell and tube heat exchanger to recover engine heat. The heat exchanger is a single - pass counterflow arrangement with temperature cross -over capability and more than adequate capacity to recover all of the waste heat currently generated. The flow is without any booster pump on the engine side of the system. Since the actual operating points of the engine -mounted pumps are not known it is assumed that the existing system is properly designed with some allowance for the low pressure drop heat exchanger. On the primary loop, a main circulation pump will be designed for the pressure drop of the furthest connected building. The pump's design flow rate will be for the maximum heat required at a 20 degree temperature drop, An air separator will be added and the existing expansion tank and glycol make-up system will be upgraded. 7.3 7.4 7.5 VW -I COLD BAY WASTE HEAT RECOVERY REPORT AN6 3 ONIC--PT CtS._jJ FE3R1;ARf .2. .yg. The piping to each of the connected buildings will be through arctic pipe(. buried underground to protect it from damage from passage of vehicles. Two separate arctic pipes are envisioned, one for supply to the building, and one for return to the power plant. See the attached Figures 5, 14, and 23 for the system schematics. for scenarios #1, 1#2, and 3. Scenario =4 is simply a combination of Scenarios #2 and #3. A system schematic is not included for scenario #5. Balancing valves are used at the connection reasons. The first is to allow balancing exchanger; the second is to provide a means of that point in the piping. Building Piping to existing piping for two of the flow to the heat measuring the flow rate at All connections to the user's buildings will be at a single heat exchange point either by using flat plate heat exchangers to connect to the boiler systems, by single unit heaters, or by return air coils where furnaces are existing. This will limit problems associated with damage of distribution piping and interconnection of systems and will enable the existing building heating system to function normally in the event of a failure of the waste heat system. One exception -to this is the School, where a second heat exchanger will be used for domestic water. This will be of the double -wall type to provide additional separation between the distribution system and potable water. Precautions must be taken to prevent overcooling of the generator jacket water and to prevent building system boilers from heating the waste heat distribution system. The simplest method is to not connect more users than the system can normally provide heat for. Each of these issues can also be addressed with controls and valving. They can also be automated to some degree but the solutions must be carefully balanced with the need for system simplicity.

SECTION 9 M 1 9.1 COLD BAY WASTE HEAT RECOVERY REPORT AND CONCEPT nESiC"; !'larch 4, FAILURE ANALYSIS Cold Bay is at least a full day away from resupply of parts out of Anchorage, and the delay might be.several days longer if weather is bad. Although the heat recovery systems are relatively simple and straight forward mechanically, the system will require some maintenance and a knowledgeable person to trouble shoot the system. Lack of. attention may render the system inoperative. It is also possible for inexperienced people to alter the system configuration by opening and closing valves or turning off pumps. Therefore, access to the system valves and controls must be limited to knowledgeable- and responsible people. The control valves must work to maintain system temperatures and the proper functioning of these valves must be checked periodically. Reports on soil conditions indicate that buried pipes should not be damaged by soil heaving or settlement if the pipes are buried correctly. The system is susceptible to mechanical damage from being hit by equipment and machinery that is used for excavation. Subsurface leaks or spills have a significant potential for soil contamination. Because of the cold temperatures', the waste heat recovery system must be filled and maintained with 30% glycol. Water without glycol must not be introduced into the system. All waste heat recovery recipients must building heating systems on line and condition to heat the building in case system fails or if the power plant is not its cooling system. Subsurface Pipe Rupture keep their respective in proper functioning the waste heat recovery rejecting enough heat to 9.1.1 Worst Case Pipe fails underground from subsidence, earthquake, corrosion, fatigue, or material fault. Glycol/water mixture seeps unnoticed into the formation or under the snow. Fluid loss continues until the pump loses suction. This problem could go unnoticed until: 1. A power plant operator notices the inlet and outlet temperatures on the primary side of the waste heat recovery heat exchanger are nearly identical or, 2. A waste heat user determines that his building is too cold or his buildings heating system is running and that the waste heat recovery system is inoperative or, COLD BAY WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN March 4, :991 Some operator or maintenance person notices the secondary temperature indicating devices are not registering proper temperatures or he notices the circulating pump(s) are running dry or, 4. Someone notices glycol/water surfacing somewhere. 5. A low pressure alarm is indicated. A further complication could arise if other controls failed concurrently. If the secondary system lost fluid and then the control valve failed to by-pass water to the generator radiators, then the engines would trip off on high temperature, producing a village black -out. A further problem could arise if the engine high temperature shut downs failed and the engine ran until over temperature failure. 9.1.2 Repair The ruptured pipe section must be. located and either repaired, replaced or by-passed. Unless the glycol surfaces, the location of the rupture may be difficult to find. Excavation will almost always be required and this may involve steam thawing the soil in winter. The alternative of by-passing the failed section with temporary �- surface waste heat piping may be necessary. An inventory of arctic pipe may be stocked at the Alaska Energy Authority Facility in Anchorage. If pipe supplies must be flown out of Anchorage, the delay could be as follows: Locating the leak, mobilizing excavating equipment, excavating leak site 2-3 days, locating pipe, ordering pipe, arranging payment and shipping 1 day, shipping 2 days, and installation of new pipe or by-pass 2-days. Total 6-1 days downtime at best. The generators could function uninterrupted. 9.1.3 Freezing/Earthquake Damage/Differential Settlement - Care must be taken to minimize potential piping damage due to differential earth movement. The sub -surface piping must be properly bedded and allowances made for known transition zones. 9 2 Above Ground Pipe Failure Leaking pipe or connection located, isolated, repaired, clean-up, 2-10 hours downtime: COLD BAY WASTE HEAT RECOVERY REPORT AND CONCEPT DESTiCN March 4. 9.3 Clean-up Of Spilled Glycol Glycol clean up. 'from facilities may be relatively easy but glycol is a health hazard and care must be taken to ensure that no one ingest the glycol mix. Glycol that spills on the ground or subsurface must be cleaned up before it enters the ground water or surface run off. The glycol must not contaminate wells, streams, lakes or salt water. 9.4 Vibration, Thermal, And Corrosion Damage To Piping 9.4.1 Vibration Insulation Devices - Must protect piping from vibration transmission particularly adjacent to vibration exciters like the diesel engines. Inadequate vibration isolation will produce cracked, broken, and leaking piping and gaskets. 9,4.2 Thermal Expansion - Joints must be installed to allow for pipe growth from thermal expansion. Inadequate provision for thermal growth will stress the system and result in strain on piping, pumps, and the heat exchangers. 9.4.3 Corrosion - Contaminates in the system or soils can accelerate the Corrosion of the piping. Additional corrosion inhibitors may be required. Care must be utilized to avoid dissimilar piping materials that could accelerate the Corrosion process. Particular attention must be paid to areas around welds and whenever there is a pressure drop in the system. 9.5 Primary Heat Exchanger Failure. Glycol leaks from heat exchanger - Operator finds leak, valves off heat exchanger and the gen-sets utilize radiators for cooling. Operators order new exchanger. If the exchanger is an "off the shelf" item, a new one could be on site in a week or 10 days. If not, it could take 10 weeks or more. Should this leak go unnoticed, gen-sets will shut down on low pressure or high temperature. The leaking area can be valved off immediately but the system must be recharged and air bled out before restarting the gensets. Downtime of "gensets 2-3 hours. This potential problem currently exists and will not be exacerbated by adding additional waste heat recovery_ 9.6 Secondary Heat Exchanger Failure Leaking or plugged secondary heat exchanger is identified, valved off, and by-passed. A replacement is ordered and the building is heated by the buildings heating plant. Down time 5 days to 6 weeks. 9 7 COLD BAY WASTE NEAT RECOVERY REPORT AND CONCEPT DESIGN March 4, 1991 Neat Exchanger Failure Modes 9.7.1 Mechanical Damage - Heat exchangers can be made to leak if damaged 'by dropping or by impacting them with power equipment,' cranes, pipes, etc. Proper- care must be. exercised to limit exposure to mechanical damage. 9.7.2 Chemical Damage - The water/glycol fluid must be monitored to prohibit developing a corrosive mixture. Also particular attention must be paid to piping gaskets and valve seat material to ensure that the materials are compatible with glycol. Dissimilar metals are to be avoided or insulated from each other. Water quality must be maintained to prevent scaling. Pump Failures The pumps are subject to thermally induced casing stress, seal failure, over -heating, voltage fluctuations, and frequency droop. The pump alignment must be checked with the piping at operative temperature. The air circulation/cooling around the pumps must not be impaired. The pump must be protected by circuit breakers from low voltage, frequency droop, and overload. The pumps must be in p parallel pairs and capable of individual isolation for replacement. The coolant in the system must not contain contaminants that will destroy the seals.. Recharging the system must be done with contaminate free water and glycol. When a pump fails from any one of a variety of causes, the stand-by pump .is activated and the failed pump valved off and repaired/replaced. System down time 0-12 hours. Replacement pump replaced 2 hrs. to 1 week. Control Failures Controls must be protected from power fluctuations and mechanical damage. Unauthorized persons must be precluded from adjusting control set points. Authorized persons must be familiar with the system and the inter -relationships of the components. In some cases it is possible for the waste heat customers to over- cool the waste heat recovery secondary piping and thermally shock the heat exchanger. It is also possible to have the waste heat customers actually heating the secondary loop coolant and then heating the generator coolant. These potential problems can be avoided by properly operating controls. Controls must be maintained and protected from corrosion and/or scaling SECTION 10 COLD BAY WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN March 4, 19-71 10.0 CONCLUSION AND RECOMMENDATIONS The final economics will be completed by the Alaska Energy Authority so a definitive conclusion is not made at this time concerning the feasibility of .a waste heat installation at Cold Bay. Some conclusions that can be made are that the project is technically feasible, that the people and agencies in the community seem quite enthusiastic about the project, and that if the economics prove acceptable, a waste heat system for the community can be recommended. To make this project more economically attractive on option would be to include this project with the construction of other waste heat systems in neighboring communities. This would help to reduce the mobilization charges. Shipping, travel and other supervision and management costs could also be combined and pro- rated for lower cost to each village. Economics are not the only yardstick by which this project should be measured. The political and social problems involved in our nations oil supply should motivate us to actively seek out ways like this to reduce our oil consumption. Environmental costs are also present with the consumption of any fossil fuel, granted they are small but present. The communities enthusiasm to participate is an important factor in the final decision to go with the project or delay until the economic situation changes to +" a more favorable one.

Values used are all calculated from 18M values reduced. proportionallyfrom'235HP to 166HP (which corresponds to 110KW prime). 8) At White Nbuntain, nameplate info recorded on engine as Cummins LTA10 and ongenerator as 140KW phme. This Is a 1200'rpm gonpet Values used are the same as described above. 9) Nameplate info recorded on en lne as AC11000 and on generator as 150KW prime. Typical AvEC data for AC11000 is 195HP/13oKW peak. This is an 1800 rpm genset. Only output data available is for fuel vs. I enerated KW electrical power from one publication and heat ou*tat2200,rpm only from another (constant 32 btu/bhp-min.). Fuel vs. engine power is given in the 2nd publication and does not correlate well with 1st publication. All values are verycluestionable. Except for fuel vs. generatoWd iCW electrical power, all values 10 used are calculated. Nam ate Into recorded on engines as AC29W and AC3500. These are 1 SM rpm gensets. Typical AVEC Idata for AC3500 is 159HP/105KW peak however this genset reportedly does not meet normal weekday loads ,which peak at less than 90KW. The AC2900 Is evert smaller. For purposes of this report the gensetsare treated as DES-60 and DES-50, respectively. These gensels use the AC2900 engine. For each 0 enset onl output data available is for fuel vs. 2enerated KW electrical power from one publ'icatlon and heat output:at 12600 rpm only and 2400 rpm only, respectlyely trom another constant 32 btu/bhp-min.).
