Power Authority staff made a visit to Chignik, where the facilities were audited for compatibility with waste heat recovery systems. Power Authority staff contacted Lake and Peninsula School District staff, as well as the City of Chignik staff. After returning from the site visit, these contacts were expanded to obtain a clear picture of power loads, fuel consumptions, future development plans in the community, etc. Staff drew up several concepts for waste heat recovery systems based on the information gathered. Staff calculated a preliminary cost estimate and the pay back time for each concept using LOTUS 1-2-3. Using relevant climatic and statistical data as well as a number of assumptions concerning future growth and fuel price development, this program simulates the operation of a waste heat recapture system over the life span of the project. This study does not include detailed gathering of engineering data such as soils conditions, local availability of skilled labor, and local experience in undertaking construction projects. Thus the cost estimates should be used with great caution. The economic analysis of system performance over the life span of the project is fairly accurate, provided that minimum maintenance is performed on the system. 1.2 Conclusion The most feasible waste heat utilization concept in Chignik is a system which would deliver heat to the Fire Hall, the School Gymnasium, and the School Utility Building. This concept would use jacket water heat as well as exhaust gas heat. An extension of service to the Community Building would not be feasible, due to the distance involved and the relatively small heating load of this facility. 1560/468(3) “1. 2.0 FACILITY DESCRIPTION 2.1 General This facility description is limited to facilities and items which are relevant in connection with waste heat recovery in Chignik. 2.2 Power Plant The Power Plant is a relatively well built and well maintained facility incorporating two Caterpillar 3306 generators, each rated at 150KW continuous power; and one Caterpillar 3304 generator rated at 75KW. Each generator has a separate skid-mounted radiator with an engine driven fan. Limited space is available inside the power plant for the installation of a waste heat system. If remote and horizontal core type radiators are used, however, the waste heat system can be installed in front of the generators. 2.3 The School The Chignik School incorporates a large Main Building, a Class Room Building and a Utility Building. Total floor area is approximately 6,200 square feet. These buildings are of BIA design and construction and are all heated from the same two boilers located in the Utility Building. These boilers also provide hot water for the school, making the connection to a waste heat system very simple. The Utility Building is located 210 feet from the Power Plant. Total fuel consumption for the Utility Building has been estimated at approximately 8,000 gallons per year. 2.4 The School Gymnasium The School Gymnasium is a 3,800 square foot Quonset hut of recent construction. The facility is very nice and well maintained inside. The heating system consists of a hot air furnace located in the attic. The ductwork leading to the furnace would allow fairly easy installation of a hot water coil between the filter and the fan. Hot water for showers, etc., is provided by an oil fired hot water heater. The furnace and the water heater are located in the east end of the building, only about 40 feet from the Power Plant. Total fuel consumption for the School Gymnasium has been estimated to be approximately 4,000 gallons per year. 2.5 The Community Building The Community Building is a fairly new and well built facility located approximately 200 feet from the Power Plant. Heat is supplied by a residential grade forced air furnace. The floor is utilized as a return air plenum. Hot water is supplied by an electric hot water heater. Total fuel consumption has _ been estimated by the City of Chignik to be approximately 1,500 gallons per year. 1560/468(4) -2- 2.6 The Fire Hall The Fire Hall, with approximately 900 square feet of floor area, is located less than 15 feet from the Power Plant. This building is currently heated by oil fired unit heaters and a future utilization of waste heat would most likely be made with hot water based unit heaters. The total fuel consumption for this building is approximately 1,000 gallons per year. 1560/468(5) -3- 3.0 WASTE HEAT SYSTEM CONCEPTS 3.1 General This section describes the waste heat system concepts that have been investigated in this study. Due to the Alaska Power Authority's extensive experience with waste heat recapture systems, this study will not attempt to investigate all possible waste heat system concepts for use in Chignik. Based on the field date collected, it seems clear to the Power Authority that several details are pre-determined. Differences between the concepts are limited to pipe routings, the number of buildings connected and, to some extent, the method of connection. All concepts studied include the following elements: ° The system would consist of a common cooling manifold in the Power Plant connected to remote, thermostatically controlled radiators. Heat would be extracted from this jacket water cooling system using a large flat plate type heat exchanger. In concepts where exhaust gas heat could be utilized, this would be done with a fin-tube type exhaust gas boiler mounted in place of the muffler. During times when the exhaust gas heat is not needed, a bypass valve would lead the exhaust gases around the exhaust gas boiler. Heat would be delivered to the user buildings through a constant output temperature, variable flow glycol based system, which would feed into an underground distribution network. The network would consist of pre-insulated pipe using a steel carrier pipe, high density urethane foam insulation and high density polyethylene jacket pipe. In buildings with hydronic type heating systems, a large flat plate heat exchanger would transfer heat to the boiler return line in the existing heating system. A simple control valve would maintain a preset temperature in the existing heating system by limiting the flow in the waste heat recovery system. With this concept, the boiler would function as an automatic backup heat source in case insufficient heat is available from the Power Plant. Buildings with existing hot air heating systems would be supplied with heat either through a hot water coil in the existing ducts or through new hot water based unit heaters. ” The use of BTU-meters or "heat meters" is not anticipated, as such meters have shown very poor reliability in rural applications. Written agreements detailing billings based on current and previous fuel consumption records will be made prior to construction of any waste heat recapture system. In the following concepts, all buildings will have equal priority concerning delivery of heat. Thus, if insufficient heat is available to satisfy all demands, each building will receive a proportionate share of its needs. If, however, one building is capable of utilizing lower grade heat than the other buildings, it will receive more than its proportionate share of the heat. From an economic stand point, this is beneficial 1560/468(6) -4- as both installation and operating and maintenance costs decrease with the buildings' capability to utilize low grade heat. 3.2 Concept A Under this concept, the School Utility Building and the Community Building would be connected to the waste heat recapture system through underground lines from the Power Plant. The School Gymnasium would be connected via a branch line connected to the main line between the Power Plant and the Utility Building. The Fire Hall would be supplied through a small diameter line suspended between the Fire Hall and the Power Plant. In the Fire Hall, heat would be supplied through one or two hot water based unit heaters with thermostatically controlled fans. In the Community Building, two cabinet unit heaters with thermostatically controlled fans would be installed. The School Gymnasium would be supplied with heat through a hot water based coil installed in the existing ductwork between the filter and the fan. Heat would be delivered to the School Utility Building via a flat plate heat exchanger installed on the boiler return line. In this concept, only jacket water heat is utilized. : 3.2.1 Concept Al This concept is identical to Concept A with the only difference being the utilization of exhaust gas heat in addition to the utilization of jacket water waste heat. 3.3 Concept B Under Concept B, heat would be delivered to the School Buildings only. Connections would be made to the Utility Building and the School Gymnasium as described under Concept A. 3.3.1 Concept Bl This concept is identical to Concept B with the only difference being the utilization of exhaust gas heat in addition to the utilization of jacket water waste heat. Only the School Buildings would be supplied with waste heat. 3.4 Concept C This concept is identical to Concept A except for the deletion of the connection to the Community Building. Thus the School Utility Building, the School Gymnasium and the Fire Hall are supplied with waste heat. Connections would be made as described for Concept A. 1560/468(7) -5- 3.4.1 Concept Cl This concept is identical to Concept C with the only difference being the utilization of exhaust gas heat in addition to the utilization of jacket water waste heat. 3.5 Concept D This concept includes connections to the School Gymnasium and the Fire Hall only. The connection would be made as described under Concept A. 1560/468(8) -6- 4.0 COST ESTIMATES 4.1 General The cost estimates presented in this report are based on the following assumptions: a. All work is performed on a "force account" basis. b. A base hourly wage of $20/hour is used for skilled labor. c. A base hourly wage of $10/hour is used for unskilled labor. d. Sufficient skilled, local labor is available. e. No mobilization of manpower or equipment is needed. f. No air freight is used. g. System design follows Alaska Power Authority standards. In the following estimates for work on each building, the laying of arctic pipe between the power plant and each particular building is included in the estimate if applicable. 4.2 Concept A Cost Estimate: Power Plant Work $ 16,360 School Gymnasium Work 6,330 School Utility Building Work 12,980 Fire Hall Work 2,470 Community Building Work 12,880 Net Construction $ 51,020 Contingency 25% 12,775 Total Construction $ 63,775 Administration, Engineering etc. 20% 12,775 Total Project Cost, Concept A $ 76,530 KREKKEKRKEREKREREREREREREREKRERERERERKEE Addition Of Exhaust Gas Boilers roy ua So So o Total Project Cost, Concept Al $ wo ry uo w oOo 1560/468(9) -7- 4.3 Concept B Cost Estimate: Power Plant Work School Gymnasium Work School Utility Building Work Net Construction Contingency 25% Total Construction Administration, Engineering etc. 20% Total Project Cost, Concept B FEI III III TAK I Addition Of Exhaust Gas Boilers Total Project Cost, Concept Bl 4.4 Concept C Cost Estimate: Power Plant Work School Gymnasium Work School Utility Building Work Fire Hall Work Net Construction Contingency 25% Total Construction Administration, Engineering etc. 20% Total Project Cost, Concept C KRIKKEKREEEEKER EKER ERE EKER EERE Addition Of Exhaust Gas Boilers Total Project Cost, Concept Cl 1560/468(10) -8- ee ua So So o ww a © a oOo oO $ 16,360 6,330 12,980 2,470 $ 38,140 9,535 $ 47,675 9,535 A uo —_ nD ee Oo we N |e ny [oO nm [Oo re 19 oOo |o 4.5 Concept D Cost Estimate: Power Plant Work $ 16,360 School Gymnasium Work 6,330 Fire Hall Work 2,470 Net Construction $ 25,160 Contingency 25% 6,290 Total Construction $ 31,450 Administration, Engineering etc. 20% 6,290 Total Project Cost $ 37,740 1560/468(11) -9- 5.0 ECONOMIC ANALYSIS 5.1 General The economic analysis for the waste heat recapture system concepts addressed in this report was performed using the LOTUS 1-2-3 software with the following methodology: ° Based on actual power production figures provided by the City of Chignik and on typical diurnal load variations compiled in other locations together with specific data for the generators in use, the available waste heat was calculated for each hour during the year. Based on heating degree variations for Chignik together with fuel consumption data and operational characteristics provided by the Lake and Peninsula School District and the City of Chignik, the actual heat demand was calculated for each hour of the year. A comparison was made between the available heat and the demand and it was then calculated how much waste heat was actually utilized. At this point, the estimated heat loss for the district heating lines was also taken into account. The waste heat utilized was added up hour by hour for the entire year. With a set of assumptions for load growth over the next 20 years, the same calculation was made for each of the next 20 years, and the annual fuel savings were derived. Based on current fuel cost and estimated fuel cost escalation together with the cost estimates presented in this report, a cash flow analysis and a pay back time were calculated for each of the concepts. Additionally, the internal rate of return was calculated for each concept to facilitate comparison of concepts with varying construction costs. Generally speaking, the pay back time indicates the period of time during which the project will have to operate as intended in order to pay off the initial investment. In this study, a discount rate of 4 percent has been used. The discount rate is approximately equal to the difference between the interest rate and the inflation rate. The internal rate of return can be used to compare feasibility of concepts without any knowledge of interest or general inflation rate. In calculating the internal rate of return, it has been assumed that the project will function as intended for 20 years. The annual operations and maintenance cost for each concept has been estimated at 3% of the construction cost. Additionally, $900 per year has been allocated for maintenance of exhaust gas boilers. 1560/468(12) -10- 5.2 Concept A Using the assumptions listed, this concept shows a pay back time of 13.3 years. The long pay back time is caused mainly by the fact that insufficient heat is available to satisfy demands in all the buildings. Only 59% of the total demand for the buildings connected can be met the first year of operation. If exhaust gas heat is utilized as explained in Concept Al, the pay back time is reduced to 9.4 years. With this concept, 96% of the heating demands are met. 5.3 Concept B If only the School Gymnasium and the School Utility Building are connected to the waste heat system, the pay back time will be 8.1 years. The School buildings alone are able to utilize all the heat available from the Power Plant. If exhaust gas heat is utilized for the School buildings alone, the pay back time is increased to 8.7 years. Under this concept the School buildings are supplied all their heating demands from the Power Plant. However, the added fuel savings does not compensate for the increase in construction costs and operations and maintenance costs, 5.4 Concept C If the Fire Hall and the School Buildings are connected to the system without exhaust gas heat utilization, all the jacket water waste heat will be utilized. This concept does not, however, compare favorably with Concept B, in which the Fire Hall is not connected. This is due to the fact that the additional connection to the Fire Hall only increases the fuel savings by 246 gallons per year. This does not justify the added construction costs, as can be seen from the 8.6 year pay back time. If exhaust gas heat utilization is added to this concept, the pay back time is reduced to 8.1 years. With this concept, almost all the heating needs of the buildings connected are satisfied with waste heat. 5.5 Concept D If only the School Gymnasium and the Fire Hall are connected to the system, a pay back time of 10.4 years results. This concept will provide all the heat needed in the two buildings; however, the total demand in these two buildings is only 5,300 gallons which limits the annual savings. Since the heating needs can be satisfied with jacket water waste heat alone, there is no need to add exhaust gas heat utilization. 1560/468(13) -11- 6.0 CONCLUSIONS 6.1 General Discussions The power plant in Chignik is very well suited for the utilization of waste heat. Current maintenance seems to be of sufficient quality that the addition of exhaust gas boilers to a waste heat recovery system can be justified. Such exhaust gas boilers require limited but regular maintenance in order to function well. Without the utilization of exhaust gas waste heat, it appears that Concept B (in which only the School receives heat) is the most economical concept. In spite of the short distance between the Power Plant and the Fire Hall, it would not be economical to provide heat to the Fire Hall if all the School Buildings are connected to the waste heat system. If exhaust gas heat is utilized, it does become economical to connect the Fire Hall to the waste heat system. The pay back time for this Concept (Concept C1) would then be 8.1 years, which is the same as the pay back time for Concept B. The internal rate of return for both concepts is approximately 14.5 percent. 6.2 Conclusion One of the most feasible waste heat utilization concepts in Chignik is a system which delivers heat to the School Utility Building and the School Gymnasium. No exhaust gas heat would be utilized in this concept. Equally feasible is a concept in which both exhaust gas heat and jacket water heat are utilized, and waste heat is supplied to the School Buildings as well as the Fire Hall. An extension of service to the Fire Hall may be marginally feasible, but it is unlikely that the provision of waste heat to the Community Building would be feasible at all. The recommended waste heat scenario is Concept Cl. This concept utilizes exhaust gas heat as well as jacket water heat and supplies this heat to the School Buildings and to the Fire Hall. Because a very low cost of fuel ($0.95/gallon) has been used in this study, Concept Cl becomes increasingly favorable in comparison with the other concepts if the cost of fuel increases more than the 2 percent assumed for this study. 1560/468(14) -12- WASTE HEAT UTILIZATION SIMULATION WORK SHEET.
