Glennallen Is located on the Glenn highway, approximately 190 miles from Anchorage by road. The heat energy could be recovered from the diesel engine-generator sets operated by Copper Valley Electric and circulated to user buildings in the community. Five possible waste heat users have been identified: the Old School Building, the Weir Building Gym- nasium, the New School Building, the Post Office, and an apartment building (Highlander Apartments). It appears as if the most economical system will provide heat to all five buildings: the Apartment building, Post Office, the Old School Building, the Weir Building Gym, and the New School Building. A summary of the construction cost estimates along with design and SIA costs is included in the Cost Estimate Appendix. If the system is installed con- necting all of the buildings, the following are the estimated results: Estimated Project Cost $647 303 Total Fuel Oil Savings 57,544 gallons Total Annual Dollar Savings $52,816 Page 1 GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 2.0 INTRODUCTION 2.1 2.2 2.3 Objective The objective of the field investigation and report is to ascertain the viability of waste heat recovery and use in the community of Glennallen. It has been estab- lished that there is a potential source and use for the heat energy, and that the community is interested in pursuing the matter. Methodology The approach for investigation and analysis has been as follows: 1 Pre-site visit information gathering: this has consisted of contact with the community officials, owners/operators of potential user buildings, and contact with the local utility. The site visit was coordinated with the local building owners/operators. 2. Field Investigation: a visit was made to the community to view the site. Photographs of the potential user buildings were taken as well as of the electrical generation buildings and equipment. Sketches were made of the equipment and piping connections. The project was discussed with local interested parties. 3. Office Analysis: additional information was collected regarding weather and historical electrical energy production. This was used in a model to predict the system performance and the amount of energy recovered. 4, Report Preparation: a draft version report was prepared for the expected audience - users and agencies with an interest. Community Description Glennallen is a community of 909 persons located on the Glenn Highway, 2 miles west of the Junction of the Glenn and Richardson Highways in the Copper River Basin. The community is 155 air miles northeast of Anchorage. Most of the terrain Is relatively level with small hills away from the highway. See Figure 3 in Section 7 for a partial community site plan. Page 2 2.4 GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 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 - 1987) National Fire Protection Association (NFPA) Codes Page 3 GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 3.0 DESCRIPTION OF SITE VISIT 3.1 3.2 Field Notes Contact names are included as part of the Appendix at the end of this report. They include both field contacts and contacts made by phone. Field Contacts The following people were contacted in the field: Dave Bruno, Service Oil and Gas Charles Mason, Principal at Glennallen High School Leland Dischman, Superintendent - Copper River School District Loreen Kramer, Business Manager - Copper Valley School District Jasper Hall, Branch Manager - National Bank of Alaska Elaine Seager, Postmaster - Glennallen Post Office Lowell Highbargin, Power Production - Copper Valley Electric Page 4 GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 4.0 POWER PLANT DESCRIPTION 4.1 Narrative Description The power plant Is located approximately one block from the Glenn Highway. The power plant facilities include the large engine building, another building for the smaller back-up engines, and a maintenance shop. On adjacent properties Is the Manager’s house and then the administrative offices. On the side of the power plant main buildings away from the highway are the remote radiators and fuel oil storage tanks. There are two each 20,000 gallon tank for storage of #4 fuel oll and two each 10,000 gallon tank for #2 fuel oil. The electric utility, Copper Valley Electric, provides power for Glennallen and vicinity. The utility is also intertied with power production facilities in Valdez. Most of Valdez's power requirement is satisfied by Solomon Gulch hydroelectric facility. Excess power from that facility is also used in Glennallen and environs. In the summer when power production from Solomon Gulch Is at its peak and all of the Glennallen load can be supplied ie the intertie, the diesel generators In Glennallen are shut down. The two main generators at the Glennallen plant are 2600 KW Enterprise diesel engine/generator sets. The units are fired with fuel oll #4 (also known as HAGO). This fuel is a high viscosity residual fuel oil from the North Pole refinery. The fuel is kept heated to 140 degrees F in exterior fuel tanks. Other smaller generators are kept in an adjacent building and are used for emergency purposes and for peak loads. These generators use fuel oil #2 which are kept heated to 100 degrees F in exterior tanks. The two main engines are connected to a cooling header. A number of small connection have been made fo this header for the purposes of plant and plant outbuilding uses. These connections Include one to heat the #4 fuel oil, one for the #2 fuel oll, one each to the maintenance shop, Manager's house, and ad- ministrative offices. The cooling piping extends to connections to two each horizontal core remote radiators outside. Separate radiators are used for the smaller generators. The power plant building appears to be in excellent condition as are the genera- tors. There is more than sufficient space for equipment should a waste heat sys- tem be installed.

The buildings were visited and information about them gathered. The information is presented below. Photographs accompany each building description. Plans and schematics can be found in Section 7. Old School General The old school is a slab-on-grade structure of wood and steel. It is currently used mostly for elementary school activities. The building has classrooms, a gym/multipurpose room, and some administrative space. The school area is ap- proximately 24,000 square feet. The building was built beginning in 1961 . Addl- tions were constructed up through 1972. It is in good general condition. Heating Energy Use A single mechanical room in the school building houses three fuel-oil fired boilers which provide all of the heating for the school. Domestic hot water is produced using a shell-and-tube heat exchanger and water from the boiler. In addition, another shell-and-tube heat exchanger is used for heating an outbuilding used as a wood shop. Refer to Table 2 for the yearly fuel oil use for the building. The yearly figures were provided by the School District. Monthly figures were estimated based on average degree days for the area. Page 9 5.3 GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 Weir Building Gym General This building is immediately adjacent and connected to the new school. It was built in approximately 1977, 10 years before the new school to serve as a full size gymnasium. When the new school was constructed, it was built as an “addition” to the existing gym. The new school is sometimes referred to as the "Weir" build- Ing because of its shape. Estimated area is 15,000 square feet. The gymnasium Is a wood and steel structure supported on piles. The major function of the building is as a gymnasium and multipurpose room. Some other smaller rooms included as part of this construction are the locker rooms, a boiler room, and some storage areas. Heating Energy Use A single fuel-oil fired boiler serves only the gymnasium/multipurpose room. The boiler capacity is 1257 MBH net output. Domestic water Is produced using a heat exchanger connected to the boiler hydronic system. Refer to Table 2 for the yearly fuel oil use for the building. The yearly figures were provided by the School District. Monthly figures were estimated based on average degree days for the area.

The new school is sometimes referred to as the "Weir" bulld- ing because of its shape. The construction took place in two phases. The first phase was completed in 1987 and included the auditorium, commons area, kitchen (for the multipurpose building), and the administration area. The second phase took place in 1988 and consisted mostly of classroom space. The addition Is of identical construction and Is essentially an indistinguishable part of the main structure. The first phase is approximately 15,000 square feet; the second phase Is 17,000 for a total of 32,000 square feet. A third phase of construction is planned but no date has been set. The planned addition is expected to include a new home economics lab and wood shop. The existing building Is In excellent condition. Heating Energy Use Both phases and the ‘planned third phase are (will be) heated from a single mechanical room in the first phase of construction. Three identical hydronic boilers are used. Each is rated at 480 MBH. They are in excellent condition. The fuel oil use reported for two years appears to be lower than expected. The average Is for approximately 50,000 BTU/square foot per year. Actual use may be higher but the recorded fuel use figures were used in the calculation process.

The building is a wood frame structure with two occupied floors, and a unfinished basement. The building is currently owned by the local branch of the National Bank of Alaska. A sale toa private individual may occur soon. There are twelve rental units in the building, each at about 780 square feet. The gross building area is estimated at 10,000 square feet. The building is currently occupied by renters. Heating Energy Use The building is heated by one two-section oll-fired boiler rated at approximately - 500 MBH. Hot water is produced by individual electric water heaters in the units. The fuel use was estimated based on the fuel oil deliveries by Service Oil and Gas. These figures however show only delivered fuel which may or may not coin- cide with actual use. The figures for approximately two years were used to deduct probable use. The estimated use Is shown In the attached Table 3.

It measures approximately 40 feet by 26 feet for an area of 1040 square feet. It is a wood and steel structure built on a pile foundation. Its only use Is as a post office. Portions of the building are acces- sible at ail time for mail box pick-up. the building is in good condition. Heating Energy Use The building is heated by a single fuel-oil fired boiler. Terminal heating units in- Clude finned tube, unit heaters, and one hydronic coil in a single air handler. Domestic hot water Is produced in an electric water heater. The estimates of fuel oil use is based on the fuel oil deliveries. Since the tank Is continually topped off at each delivery, it ls considered a reasonable method of estimating actual use. The estimated use follows In Table 4, Page 22 PHOTO 17: POST OFFICE Exterior Elevation PHOTO 18; POST OFFICE Existing Boiler System Page 23 TABLE 4 POST OFFICE FUEL USE - 1988 & 1989 11/1/88 11/2/88 FUELOIL j|NUMBER DELIVERED |OF DAYS APSED GALLONS OF FUEL USED 563 12/2/88 38 12/21/88 880 46 1/23/89 982 30 1/26/89 934 311 2/13/89 064 59 3/2/89 664 37 3/21/89 530 28 3/31/89 455 46 4/18/89 648 36 5/11/89 330 11 6/6/89 300 12 7/24/89 170 4 10/17/89 569 85 7 11/20/89 1942 34 57 12/6/89 897 16 56 12,618 EST.

This information in- cluded a review of available aerial photos, U.S. Geological Survey information, plats, and Alaska Department of Community and Regional Affairs data. The only aerial photos available were taken in August 1983 and therefor do not include the new construction at the high school. The only other local source for informa- tion was the Anchorage Recorder's Office. The office had information available from 1963, 1964, and 1974. Complete plats were not available but information was found for the Apartment, Post Office, and power plant properties. Since Glennallen has its own recording district, additional information might be ob- tained through searching of their archives. Right-of-way Information on the plats was limited. An easement is shown on the north side of the Post Office property, and an easement runs through the center of the apartment building (north and south). The legal descriptions of the properties are as follows: School: Township 4 North, Range 2 West, Copper River Meridian. Section 23 East 1/2 Northeast 1/2 Southeast 1/4 containing 20 acres more or less. U.S. Post Office: Tract A, Section 3 of Heintz Subdivision, Plat #74-442 of Chitina recording District. Apartment Building: Lots 1, 2, 3, 15, 16, 17 Block 4, Section 2, Heintz Sub- division. PowerPlant: Lot 1, Co-op Subdivision, Plat #67-239 Chitina recording District. Page 25 GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 7.0 CONCEPT DESIGN 7.1) System Narrative In keeping with the previous AEA recommendations, the current concept design includes one flat plate heat exchanger at the power plant. The flow will be without any booster pump on the engine side of the system. Since the actual operating point of the engine-mounted pump is not known it is assumed that there is some allowance for a 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. In addition, an air separator, and ex- pansion tank, and a glycol make-up system Is required. The pump’s design flow rate will be for the maximum heat available at a 20 degree temperature drop. 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 Figure 2 for the system schematic. Balancing valves are used at the connection to existing piping for two reasons. The first is to allow balancing of the flow to the heat exchanger; the second is to provide a means of measuring the flow rate at that point in the piping. All connections to the user buildings will be using flat plate heat exchangers. This will limit problems associated with damage of distribution piping and intercon- nection of systems. 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. Each of these issues can 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.

The fuel is purchased based on a negotiated rate. Fuel oil costs for the Post Office (#1 only) is currently $0.91/gallon while the Apart- ment building, using #2 fuel oil is currently paying $0.957/gallon. Displaced Costs Due to Heat Recovery The calculations that model the waste heat system are shown in the Appendix at the end of this report. These calculations essentially make comparisons of the waste heat available to the waste heat demand of the connected buildings. These comparisons are made for each hour of an average day of each month of the year. Since it may not be economically feasible to connect all of the potential build- ings, the calculations were made in a logical order of building connections, that is, the nearest building was modeled as being connected first. In this proposed order, the high school was connected first, then the Community building, and last the Treatment plant. The results of the calculations based on the most recent fuel oil costs were as fol- lows: CONCEPT GALLONS SSAVINGS 1A 6,905 $6,608 1B 15,430 $14,366 2A 38,316 $35,A33 2B 57,544 $52,844 Page 49 8.3 GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 Summary Cost Estimate The assumptions for the cost estimate was that bidding would take place In April of 1990. Prevailing local wages as defined by the Department of Labor were used. The cost estimate is presented with costs identified for the total project, but broken out separately to show the component costs for the work at the power plant, for the arctic pipe, and for each of the connected buildings. Since there can be much more energy demand than is available with the con- nected buildings, the cost estimate Is organized in an additive alternate form. Energy Authority SIA (Supervision, Inspection, and Administration) costs are in- cluded in the figures shown below.

The analysis of the system will help guide the direction of the design to avoid systems with increased failure rates and repair costs and reduced waste heat recovery effectiveness. 9.2 Identification of Major Components The following components are those whose failure Is likely In the normal course of operation and whose failure could affect the operation of the generator or waste heat recovery systems. A brief description of the component follows the identification. Circulation pump(s): This is the pump (centrifugal) that will be used to cir- culate fluid from the heat exchanger In the power plant to the user buildings through the arctic pipe. This discussion.also applies to booster pumps (in-line type) that can be used In the user buildings to help overcome the additional pressure drop of the waste heat recovery system heat exchanger. A pump may also be used on the generator side of the system to help overcome the added pressure drop of the heat exchanger or the case where hydronic coils have been added to an all air system. Jacket Water Heat Exchanger: This component is the device used to transfer heat from one liquid to another. In the design presented here, it is a flat plate, or plate and frame type heat exchanger. The device consists of vertical plates separated by gaskets with the fluid of one system flowing in alternate plates heating (or cooling) the other fluid. There are no moving parts during operation. Stack Gas Heat Exchanger: This Is a device similar in concept to the jacket water heat exchanger with the exception that the-fluids being considered include both a liquid (the waste heat recovery transfer medium) and a gas - the exhaust gases from the engine. Although there are no moving parts, the heat exchanger surface is subject to very high temperatures from the exhaust gases (to 1400 degrees F). Radiator(s): These devices are part of the generation system rather than the waste heat recovery portion. They are used to provide cooling for the engines by transferring heat from the engine coolant to the atmosphere. In conjunction Page 52 9.3 GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 with the waste heat recovery system, they would be used only when cooling Is required beyond the cooling that has occurred through the use of waste heat by the recovery system. Control Valve(s): Control valves are used to maintain a setpoint tem- perature at a specific location in a piping system. In the case of the generation system, they often are the self-contained type as manufactured by Amot. The valve operator movement is based on the expansion of wax in the valve case. Alfematives are an electrically operated valve to serve the same function. Exterior piping (arctic pipe): The arctic pipe is a pipe-within-a-pipe system used for transferring fluid between locations. The center pipe, or carrier pipe is used for fluid transfer. The carrier pipe is insulated to reduce heat transfer. Outside the insulation Is a second pipe called the jacket. This is used to protect the insulation. Interior piping/valves: This portion of the system is found at the power plant or at the user buildings. Its purpose Is to transfer and control the fluid to the com- ponents of the system. Failure Mode and Impact For each of the components Identified above, the likely mode or modes of failure is discussed. These failure modes have been surmised based on conversations with equipment manufac- turers and based on engineering experience and judgment. In addition, the impact of failure on the generation and the waste heat recovery system is gaged as is the environmental effects. Recommended immediate actions by the system caretaker are also noted. Circulation pump(s) Failure Mode: The pump assembly can fail by the failure of its in- dividual components. These include shaft seals, shaft bearings, motor, impeller, or casing. Impeller or casing failure is not expected to occur before the life of the com- ponent has been reached. This life is expected to be 15 years. Generator Operational Impact: Since failure of a booster pump used on the gener- ator side of the system could result in a high-temperature shut-down of the engine, its use Is not recommended. The likely reason for addition of a booster pump Is to over- come additional pressure drop imposed by the system by new heat recovery equip- Page 53 GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 ment. To avoid the need for the pump, the system should be designed to keep addi- tional pressure drop below the maximum rated pressure drop of the engine mounted pump. Waste Heat System Operational Impact: Where only a single circulation pump has been installed for heat transfer services, Its failure Could result In complete suspension of heat recovery. Shaft seal and shaft bearing failures in their early stages would have little effect on operation but could eventually reduce heat recovery to zero after complete failure. When duplex pumps have been installed, the heat recovery will be affected only until the standby pump can be put into service which can occur minutes after the failure is noted. Environmental Impact: Minor - a shaft seal failure could result in a slow fluid leak that could reach the ground outside. Required Immediate Actions: If no significant loss of fluid has occurred (due to shaft seal failure), replacement of the pump will restore the system to service. The pump should be Isolated with the valves on either side of the pump, fluid checked and proper fluid level restored as needed, and the back-up pump (if installed) started. Jacket Water Heat Exchanger Failure Mode: Since there are no moving parts, the failure of this component can occur from failure of the gaskets, or failure on the frame or plates. Since the plates are generally of stainless steel, failure is unlikely during the rated life of the equipment - or approximately 20 years. The frame Is also unlikely to fail during the 20 year life. The only probable failure during the life would be the gaskets, probably exhibited as a slow leak that worsens with time. Generator Operational Impact: If the gaskets failed serving the generator cooling system fluid, enough fluid could leak out to cause a low water shut-down of the engine. Waste Heat System Operational Impact: Similar to the scenarios above, if fluid from the waste heat system were to leak from failed gaskets, the system could be in- capacitated. Page 54 GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 Environmental Impact: A major loss of the fluid, most likely an ethylene glycol mix- ture could have some environmental impacts. Ethylene glycol is toxic. The problem could be reduced by using propylene glycol which is potable. The problem that often results when using propylene glycol is failure of operating or maintenance personnel to use compatible glycol for system make up. Required Immediate Actions: If an engine side gasket has failed, the heat ex- changer should be bypassed and manual shut-off valves used on the leaking side. If the leak occurs on the waste heat side, isolation valves should be closed and the circulation pump shut off. Stack Gas Heat Exchanger Failure Mode: Three mechanisms can lead to this component failure. The first Is through operational wear. This wear is caused by the passage of hot exhaust gases over the heat exchanger surface. The failure through this mechanism determines the life of the equipment which is approximately 5 years. Two other forms of failure can occur: the first Is through thermal shock by passage of relatively cold fluid into the exchanger which has been heated to the exhaust gas temperature. Sudden contraction will destroy the heat exchanger. The second type of failure could occur if the heat exchanger is kept at too low of a temperature allowing sulfuric and hydrochloric acids to form from the exhaust gases. Rapid corrosion would result in the heat exchanger failure. Generator Operational Impact: If the heat exchanger Is located away from the generator, its failure would probably not release glycol onto the engines surface. Since the flow path of the exhaust gases would not be any more restricted after failure, no significant backpressure is expected to develop. If the stack gas heat exchanger is used to heat fluid after passing through the main jacket water heat exchanger, no loss of en- gine coolant will occur. However, to avoid pipe contamination, the generator should be shut down. If available or designed, a bypass-.device that allows exhaust gases to fol- low a path away from the heat exchanger would allow generator operation with a damaged or missing heat exchanger. Waste Heat System Operational Impact: Tne waste heat system would be disabled by a sudden stack gas heat exchanger failure. Environmental Impact: The loss of fluid to the environment could represent a problem as outlined in previous discussions. Page 55 GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 Required Immediate Actions: After failure of the stack gas heat exchanger, the exchanger should be isolated with valves and a bypass mechanism used for the stack gases. Fluid snould be added to make up for losses, and lost fluid collected where pos- sible. Radiator(s) Failure Mode: The main component of the radiators Is the heat exchanger for cooling of the liquid. The heat exchanger is expected to last the life of the radiator or 15 years. The other modes of failure are similar to for circulation pumps: shaft bearings or motors, or controls. The controls in this case are assumed to be variable speed controls for the fan motor. Generator Operational Impact: Failure through leakage would drain the fluid and cause a low water shutdown of the generator. Failure of the fan-related hardware would result in insufficient cooling and a high-temperature shut down. Waste Heat System Operational Impact: Tnere would be no effect on the waste heat system until generator shut down. At that time of course, no more heat would be avail- able for recovery. Environmental Impact: The only environmental impact would be if a leakage failure occurred which Is not the highest probability failure. Required Immediate Actions: The radiator should be isolated and an altemate radiator used for cooling until repairs can be made. Control Valve(s) Failure Mode: The valve casing is expected to last the life of the valve or 20 years. The most likely failure before the life is reached is that of leaking seals or seats, or failure of the operating mechanism. The seal or seat failure will normally result in a low-loss leak of fluid until repaired. The control mechanisms that can be used In this instance include Amot type operators which use the expansion characteristics of wax to operate the valve or electric motor driven operators. Although Amot-type operators fail less fre- quently than electric motor operators, they have the disadvantages of less control (which means less heat recovery) and do not indicate current control position. Page 56 GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 Generator Operational Impact: Failure of the operators will normally result in loss of control. Often time these failures can occur at a mixing condition which may not im- mediately cause a system failure. The extreme cases would result in overheating. Waste Heat System Operational Impact: As discussed above, a failure in a mixing mode may not cause complete failure, but it is possible. Environmental Impact: Minor - only small leaks normally develop through seal and seat failures, Required Immediate Actions: The valve should be isolated as soon as the seat or seal failure is discovered. If the failure is an electric operator, the valve could be manually positioned to an acceptable position until the operator can be replaced. When an Amot-type valve Is used, manual bypass valves can be used. Exterior piping (arctic pipe) Failure Mode: The only failure mode likely to interfere with the system operation would be a fluid leak at a joint. Generator Operational Impact: None. Waste Heat System Operational Impact: —_A significant leak would shut down the sys- tem. Environmental Impact: The leaking fluid could drain the entire piping system. Required Immediate Actions: The pump would be turned off, the system drained as much as possible, and the leaking line Isolated as close to the leak as possible. Interior piping/valves Failure Mode: Interior piping joints will normally last the length of the pipe life - about 20 years - unless physically damaged. The valves may suffer the same failures as men- tioned above for control valves. Generator Operational Impact: A fluid leak would generally be small but it is pos- sible that enough fluid would leak until a low water shut down occurred. Waste Heat System Operational Impact: Same as for Generation system effect. Page 57 GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 Environmental Impact: Minor. Required Immediate Actions: Isolate the leaking valve, shut off pump if fluid loss is significant. 9.4 Failure Frequency and Cost Frequencies of failure have been estimated based on conversations with manufacturers and on engineering Judgment. Assumptions made regarding the repair include: On-site operator's skill are that of a "caretaker." Skilled preventive maintenance is performed 3 times yearly. A one day weather delay is included for all winter repair trips. Travel to site for repair is via jet, and then charter. Skilled mechanics are mobilized from Anchorage, Fairbanks, or Juneau as ap- propriate. Costs are based on $43/hour labor costs. Travel time is 12 hours round trip. Travel cost Is $600 round trip. Subsistence costs are $100 per day. OQRONn> Ps FP Circulation pump(s) Most common failure: Shaft.seal, shaft bearings, or motor.

This recommendation is due to the sensitivity of the equipment to operator error and the delay that could be encountered in returning the system to service. Other recommendations include design of duplex pumps so that damaged pumps will not halt service for any length of time. This type of approach can also be extended to spare parts stock so that some failures may be attended to during the preventive maintenance visits to reduce costs. To avoid compromising the reliability of the generation system, booster pumps of the generator side should be avoided. A way to avoid the need for the pumps Is to design the heat ex- changer and piping system to be as low as possible and to be less than the maximum recom- mended external pressure drop as listed by the engine manufacturer. Although the failure rate of the electric motor operators on control valves is higher than for self- contained Amot-type valves, the additional control and heat recovery may provide incentive for their use. To keep an increased level of reliability of building heating systems, it is also recommended that any building connected the waste heat recovery system use a heat exchanger. In the event of a distribution piping failure, the building’s heating system would continue to operate without in- terruption. Page 61 GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 10.0 CONCLUSIONS AND RECOMMENDATIONS The final economics will be completed by the Alaska Energy Authority so a definitive conclusion Is not made at this tine concerming the feasibility of a waste heat installation at Glennallen. 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. Two graphs follow this page that illustrate the current waste heat situation in Glennallen. The first graph entitled "Heat Available Vs. Heat Required" shows the relationship be- tween these two quantities for each month of a year. The lowest line represents the heat available from the power plant in terms of equivalent gallons of fuel oil. Each of the other three lines represent a construction option: the concept 1B, the concept 2A, and the concept 2B. The second graph Is entitled "Fuel Oll Displaced” and shows the amount of recovered energy in equivalent gallons of fuel oil for each of the three construction options for the year. A similar shape as was shown in the previous graph is displayed. Page 62 e9 ebeg GLENNALLEN WASTE HEAT RECOVERY HEAT AVAILABLE VS.

The information Is for each month of a year. The year is assumed to be either an average year or a represen- tative year. The power production information must include the amount of power produced for each month of a year and the amount of heat rejected to the Jacket water for each KWH of power produced. The power production is from historical records and the heat rejection data is from the manufacturer of the engine/generators being used for power production. The fuel use data Is for each of the potential waste heat user buildings. It is fuel oll use for each month of the “average” year. It Is also assumed that the fuel oil use reported here is only for heating energy that can be displaced by waste heat recovery. It would not include fuel oil used by a separate fuel oil-fired water heater. The information ideally should be based on historical information but can also be estimated on a monthly basis for yearly fuel oll use. The system heat loss is a number that represents the energy that Is rejected to the jacket water, but is lost or used before It can be used by the end user buildings. Examples of this system loss can include: heat loss of the generator cooling system piping, heat loss from the arctic pipe, and heat recovery in the power plant for space heating or fuel oil heating. This figure must be estimated based on available information. Assumptions The most important assumptions made in this model are the diurnal variation of the heat demand, and the power production. The figures shown in the calculations represent a ‘typical’ pattern for rural environments. Tne heating demand follows an approximate sine curve with minimum demand at solar noon, and maximum demand at solar mid- night. The diurnal variation for power plant production is less regular. The variation as- sumed has peaks in the moming (around 8:00) and near noon and at 6:00 pm. The lowest power production occurs near midnight. GLENNALLEN WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN JANUARY 15, 1990 When calculating the energy demand for the buildings based on their fuel oil use, it is as- sumed that each gallon of fuel oil corresponds to 100,000 BTU. This represents ap- proximately a 71% efficient boiler or fumace. Actual efficiencies will vary. Calculations The heat available is calculated by dividing the monthly power production by the num- ber of days in the month - yielding the power production on an average day, then by multiplying that figure by the hourly power production variation for each hour. This is the power produced for each hour of the average day of the month. This figure Is multiplied by the manufacturer's factor for heat rejected to the jacket water. The result is the gross heat available at the power plant on an hourly basis. The system heat loss is subtracted from the gross amount, leaving the amount available for building use. The heat required by the buildings is accomplished in a similar manner. The sum of all the buildings fuel use is multiplied by 100,000 BTU/gallon and adjusted to yield the hourly heat demand for the average day of the month. The heat recovered Is just the smaller number of the heat avallable and the heat demand; if the heat available is larger than the heat demand, all of the heat available will be used. If the reverse Is true and much more heat Is available, then all of the bulld- ing heat demand requirements will be met. The number of gallons displaced also as- sumes that each 100,000 BTU corresponds to one gallon of fuel oil.
