Noorvik is lo- cated on the banks of the Kobuk River, approximately 520 air miles north-northwest of Anchorage. The heat energy could be recovered from the diesel engine-generator sets operated by AVEC and circulated to user buildings in the community. Three possible waste heat users have been identified: the high school, the Community building, and the Water/Wastewater Treatment building. It appears as if the most economical system will provide heat only to the high school since It Is closest to the power plant and can use almost all of the available heat. A sum- mary of the construction cost estimates along with design and SIA costs Is Included in the Cost Estimate Appendix. If only the base bid system Is installed connecting only to the high school, the following are the estimated results: Estimated Project Cost $283,316 Total Fuel Oil Savings 16432 gallons Total Annual Dollar Savings $17,750 Sigh Page 1 NOORVIK WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN DECEMBER 15, 1989 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 Noorvik. It has been estab- lished that there is a potential source and use for the heat energy, and that the community |s 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 bulldings, 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 bulldings 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 Noorvik is a community of 384 persons located on the banks of the Nazuruk Channel of the Kobuk River. The community Is 33 miles northwest of Selawik. Most of the community follows the terrain of the river bank. A small hill is located at the west end of the community. See Figure 1 in Section 7 for a community site plan. Page 2 2.4 NOORVIK WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN DECEMBER 15, 1989 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 NOORVIK WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN DECEMBER 15, 1989 3.0 DESCRIPTION OF SITE VISIT 3.1 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. 3.2 Field Contacts The following people were contacted in the field: Cheryl Sampson, City Administrator Flora Carter, AVEC plant operator Donna Zabel, High School Principal’s Secretary David Denig-Chakroff, AEA Susan White, AEA Page 4 NOORVIK WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN DECEMBER 15, 1989 4.0 POWER PLANT DESCRIPTION 41 4.2 43 Narrative Description The site Is located on the road between the airstrip and the community Itself. The site consists of one module for switchgear and instrumentation, three separate modules each housing one generator and remote radiator, two small structures used for storage, and fuel oll storage tanks. Each of the modules Is an "ATCO" prefabricated unit, approximately 10 feet wide by 24 feet long. Inside each of the generator modules Is an engine/generator set housed in a room approximately 17.5 feet long and the width of the module. In the at- tached room at the north end of the modules, separated by a door, Is the remote radiator, cooling piping, and heat exchanger. The heat exchanger Is a shell and tube type. The heat transferred from the cooling system is used to heat the modules themselves using a unit heater in each module. No pump was found for circulation of this heating fluid. A 3/4" pair of lines runs interconnected between all of the modules, running through a small wooden utllidor between the modules. The line serves unit heaters located in each of the three modules. Cooling is accomplished through wall mounted axial fans. A single control sys- tem controls both the heating and cooling based on a thermostat located in the space. The power plant uses two Caterpillar 3412 engine/generators rated at 340 KW and one Caterpillar 0342 rated ar 185 KW. The D342 Is rarely used. There are no immediate plans for changes to the generating system. Part of the long term plan Is to replace the D342 (within 10 years).

These three buildings are the Noorvik High School, the Community Building, and the Water/Wastewater Treatment Building. The three 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. Noorvik High School General Tne building is a wood and steel structure on piles with approximately 20,000 square feet of conditioned space. The building is used mostly for educational purposes although there is some use of the gym and kitchen area for special events. The main portion of the building was constructed approximately 15 years ago. An addition was made 9 years ago which added the shop. science, and junior high reading areas. The building appears to be in good condition. Heating Energy Use The original portion of the school is heated through indirect fuel oil-fired furnaces located in a fan room above the administrative area, adjacent to the gym- nasium. Two fuel oil-fired water heaters are also located in this space. The equipment appears to be in good condition. Tne space added 9 years ago is heated separately through the use of two boilers located in the addition. The equipment appeared to be in good condi- tion. No fans were found other than make-up air units for welding exhaust which did not appear to receive more than very occasional use. Page 10 5.2 NOORVIK WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN DECEMBER 15, 1989 See the attached Table showing the approximate fuel use for 1988. The fuel use shown is from school records of the current fuel oil inventory. 10% of the fuel use was assumed to be for domestic water heating purposes and was deducted from the total. The actual inventory figures were averaged where more than one month of fuel use was known, and adjusted for gaps in the records. Noorvik Community Building General The building is a wood frame structure on piles two stories in height. A portion of the building is open from the bottom floor to the roof. The building has ap- proximately a 3200 square feet footprint, with an estimated 4400 conditioned square feet. It is used for community administrative spaces and for meeting pur- poses. The building is in fair condition. Heating Energy Use Two different methods of heating are available to the Community Building. One indirect fired unit heater is located in the main meeting room (which is open to the second floor). It is more economical to use this system, but is noisy, does not distribute the heat throughout the spaces well, and can be uncomfortable for those in the meeting room. The means for water heating in the space is not known and its use would be quite small, only for one lavatory and one sink. The second form of heating available is through the use of the hydronic boilers located in a small module adjacent to the Community Building. The boilers heat water which is zoned in the boiler room, and then piped over to the Community Building through a small wooden utilidor attached to the underside of the build- ings. See the attached Table outlining the fuel use for the buildings (for the Com- munity and the Treatment buildings). The figures shown were provided by the community office in terms of yearly fuel use. The monthly use was calculated based on the heating degree days for the area. Page 11 NOORVIK SCHOOL FUEL OIL INVENTORY (INCLUDES ELEM.

The actual age is unknown and the condition of the building Is good. The size of the building is estimated at 50 feet by 100 feet, for a 5000 square foot area. The building houses the equipment used for water and wastewater treatment. In addition, a 100,000 gallon water storage tank Is located in the space. A portion of the building Is also used for an apartment by a private individual. Heating Energy Use Besides the energy required for space heating of the building, energy Is also con- sumed for the purpose of keeping the utilidor temperature high enough to prevent freezing. This purpose is accomplished through the use of glycol heat trace lines. The glycol is heated In the treatment building for circulation through the utilidor. The heating energy Is used via two hydronic boilers located In the treatment building. The boilers also have small domestic water heat exchangers located in the casing. The hot water is used for the apartment and other uses around the building. The hydronic system serves four unit heaters located at the corner of the building, and is also used to heat the glycol utilidor circulation system through shell and tube heat exchangers also located within the building.

Page 20 NOORVIK WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN DECEMBER 15, 1989 7.0 CONCEPT DESIGN 7.) System Narrative In discussion with Peter Hansen of the Alaska Energy Authority, Mr. Hansen recommended some general guidelines for the design of the waste neat recovery systems. His recommendations were the following: 1, Use flat plate heat exchangers in series, one for each of the generators that may be used. 2. Connect the High School system using another flat plate heat exchanger. Connections to the other two buildings can be direct, with no neat ex- changer. 3: System design should be for at least a 15 degree F temperature drop to keep flow rates as low as possible. In keeping with the above recommendations, the current concept design in- cludes two flat plate heat exchangers at the AVEC modules. The two heat ex- changers are for each of the normally used engine/generator sets. The flow will be in series through the two heat exchangers without any booster pump on the engine side of the system. Since the actual operating point of the pump is not known it is assumed that there is some allowance for a low pressure drop neat exchanger. One 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. Tne 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 AVEC plant. See the attached Figure 1 for the system schematic.

The coil design will be for a single row coil with wide fin spacing to minimize the air pressure drop and its effect on air flow to the rooms. The connection to the Community and the Treatment building will be with a heat exchanger to reduce the potential problems with building system overpressuriza- tion and loss of heating fluid in the event of a pipe leak. The piping will be con- nected into the return lines of the boilers and circulated with the existing in-line circulating pumps. 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. Site Plan/Routing The routing will be as shown on the attached plan. Essentially, a direct line-of- sight connection is envisioned first from the AVEC plant to the high school, then from the high school to community building, and then to the treatment plant. The routing is shown on Figure 2. Generator Room Plans/Schematics See the attached Figures 3 and 4 for the design concept for changes to the AVEC modules.

Page 40 NOORVIK WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN DECEMBER 15, 1989 8.0 ECONOMIC DATA 8.1 8.2 8.3 Current Fuel Oil Costs Fuel oil costs for High School were $1.08/gallon for fuel purchased in 1989, and $.80/gallon for fuel purchased in 1988. The fuel is purchased through the Bureau of Indian Affairs (BIA) and is lower in price than what is available to other con- sumers in the community. Fuel oil costs for the community of Noorvik, for both the Community building and the Treatment building have been $1.41/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. Tnese 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: High school only 16A32 gallons saved ($17,750) H.S. & Comm. bidg. 17,957 gallons saved ($19,900) All three buildings 19,269 gallons saved ($21,750) Summary Cost Estimate Tne 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 AVEC plant, for the arctic pipe, and for each of the connected buildings. Page 41 8.4 NOORVIK WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN DECEMBER 15, 1989 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. Tne base estimate assumes connection to just the high school and the additional cost for connection to the Community building and the Treatment building are shown separately. Energy Authority SIA (Supervision, Inspection, and Administra- tion) costs are included in the figures shown below. High school only $261,522 (base bid) H.S. & Comm. bidg. $94,194 (additive alt. #1) All three buildings $20,443 (additive alt. #2) Estimated Component Life and Maintenance Costs The following estimates of maintenance cost were made based on the in- cremental cost of technician who is already on-site. Assumptions were made for each of the pieces of equipment regarding frequency of inspection and repair. The total yearly maintenance cost will depend on the scope of installation. The costs for both the base bid and alternate #2 are shown. ttem Life (yrs) Maint, Cost ($/Yn Heat Exchangers 20 $126 (each, 4 total) Circulation pumps 15 $112 (each, 2 total) Arctic Pipe 16 $210 ¢total) Interior piping 16 $70 (each location, 5 total) Interior valves 15 $140 (each location, 5 total) Expansion Tank 15 $70 (each, 2 total) Air Separator 16 $35 (each, 2 total) Glycol 16 $180 (total) Coils 20 $105 (total) TOTAL (Alternate #2) $2483/year TOTAL (base bid) $1811/year Page 42 9.0 NOORVIK WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN DECEMBER 15, 1989 CONCLUSIONS AND RECOMMENDATIONS The final economics will be completed by the Alaska Energy Authority so a definitive conclusion cannot be made at this time concerning the feasibility of a waste heat instal- lation at Noorvik. 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 Noorvik. The first graph entitled "Heat Available Vs. Heat Required" snows 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 base bid, the alternate #1, and the alternate #2. As the graph demonstrates, the waste heat available is less than the heat energy required by the high school alone in all months except for the summer months. The second graph is entitled “Fuel Oil 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. If either of the additive alternates are accepted, only a small amount of additional energy would be saved since the school is using all of the available waste heat except during the sum- mer.

Cost Estimates NOORVIK WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN DECEMBER 15, 1989 Calculations NOORVIK WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN DECEMBER 15, 1989 WASTE HEAT RECOVERY CALCULATION METHOD Input Before the calculation of recovered waste heat can take place, the user must input in- formation about power production, fuel use, and system heat loss. 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 oll 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 diumal variation of the heat demand, and the power production. The figures shown in the calculations represent a ‘typical’ pattem for rural environments. The heating demand follows an approximate sine Curve with mininum 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. NOORVIK WASTE HEAT RECOVERY REPORT AND CONCEPT DESIGN DECEMBER 15, 1989 When calculating the energy demand for the buildings based on their fuel oll use, It is as- sumed that each gallon of fuel oll 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. Tne heat recovered Is just the smaller number of the heat available 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 ttue and much more heat Is available, then all of the build- 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.
