SUMMARY Savoonga: The waste heat system is operational and working well. A small leak in the waste heat arctic piping was patched. The BSSD has written a letter to AEA stating that they are "not convinced that the system works well enough for us to continue making future payments" for waste heat. The City has scheduled a meeting for March 6th at 1:00 pm to discuss their proposed bulk fuel upgrade. Elim: The waste heat system which serves the Elementary School and High School is working. The waste heat supply temperature is about 178 degrees and provides good heat to both facilities. Golovin: Information was obtained to design the upgrade to the City bulk fuel plant upgrade. Also, the waste heat system installed in 1988 was inspected. White Mountain: I stopped in on my way back to Nome to meet with the Mayor regarding the installation of a waste heat system and to collect additional data for a cost estimate. TRIP REPORT Savoonga - Monday 2/10/92 and Tuesday 2/11/92 (15F, windy & white out conditions) I departed Anchorage on Alaska Airlines at 8:30 am., and arrived in Nome at 10:25 am., departed Nome at 3:00 p.m. on Bering Air and arrived in Savoonga at 4:00 p.m. I caught a ride over to the school and met with Jim Lewis (Principal 984-6811) and Morris Toolie (School Mtc). Morris showed me where the arctic pipe was leaking and I patched it using a neoprene "bandaid" and high temperature RTV silicone and clamps. I then fastened 2x4 boards to the ceiling to reinstall the arctic pipe pipe supports at the entrance to the school boiler room. After a futile attempt to raise the arctic pipe back up to the hangers, I decided to wait until next summer after the snow and ice melts off of the pipe. All valves were inspected for correct settings. All were OK except that the heat exchanger bypass valve was open 3 notches. The boilers were set to fire from 150 to 175/180F. I recorded the following waste heat system data: Boiler Loop: Into HXR: 142 degrees Out of HXR: 152 degrees Waste Heat Loop: Supply: 155 degrees Return: 140 degrees The waste heat system glycol mixture was tested and determined to be 47% ethylene glycol with an inhibitor level of 8 (good) (A 30% ethylene glycol mixture will provide burst protection to -60F). The water makeup system was off. Iinstalled a pressure gauge in the waste heat return line in the boiler room. The pressure varied between 11.5 and 12.5 psi with the circulating pump on and 6 psi with the pump off. I provided Mr. Toolie with some more waste heat temperature logs and requested that he fill them out daily and send me a copy at the end of each month. I checked the glycol concentration of the school heating system and found there is only 20% propylene glycol in the system. A solution of 35% is required to provide burst protection to the piping. I explained to both Mr. Lewis and Mr. Toolie that the waste heat return temperature is "driven" by the boiler return temperature (temperature of the heating water returning (HWR) from the building to the boiler). Since the HWR temperature was 142, the waste heat return temperature was about the same. Any time the waste heat return temperature falls below 160F the diesel engine thermostats start to cycle closed and bypass coolant internal to the engine which reduces the effectiveness of the waste heat system and lowers the waste heat supply temperature. (Apparently, the school heating system flow rate is too low. The ambient temperature on Tuesday 2/11/92 was about 25F and sunny. The HWS from the boilers was 175 to 180, yet the HWR was only 142F. Boiler manufacturers typically suggest a maximum temperature difference of 30F across a boiler to prevent thermal shocking and cracking the boiler. As can be seen from the above temperature data, the temperature drop was about 35F on a very mild day. I will alert the district to this situation.) After our discussion, I raised the low limit on the boilers so that they fired 160 to 175/180. After three hours I recorded the following data: Boiler Loop: Into HXR: 150 degrees Out of HXR: 158 degrees Waste Heat Loop: Supply: 164 degrees Return: 148 degrees Pressure: 11 psi Waste Heat Module: I met Steve Flowers (AVEC Field Technician) at the power plant. Mr. Flowers showed me some of the work he had accomplished including installing new stainless steel braided flex hose between the power plant and the WHM and a new S&T heat exchanger for plant heat. At the WHM, the valves were inspected for correct settings. All were OK except the normally open 3/4" amot bypass valve was closed. I pointed this out to Mr. Flowers and explained that the valve is designed to be open to allow some flow to the radiators at all times to prevent the radiators from being at ambient temperature. Position #1 (KTA 1150) was on line and carrying a load between 180 and 220 kW. The engine supply temperature was 184 in and 178 out of the AVEC plant S&T H/E. The following data was recorded: Waste Heat Loop: Pressure: 10 psi Supply Temp: 160 degrees Return Temp: 150 degrees AVEC Loop: Into HXR: 176 degrees Out of HXR: 152 (into AMOT & Rad's) Eng Rtn: 152 degrees I left several clamps, some RTV silicone and neoprene rubber for Mr. Flowers in case of any other arctic pipe leaks. Prior to departing, I met with Mayor Warren Toolie and Council Member Myron Kingeekuk regarding the City's bulk fuel system upgrade. They informed me that a meeting was scheduled for March 6th at 1 am in Savoonga to discuss the project and that Sue White would receive an invitation to attend. I also collected some information on bulk tanks in the community. I departed at 7:45 pm and arrived in Nome at 9:15 pm. Nome - Wednesday 2/12/92 (25F, Foggy and Windy) I was weathered in Nome for the day. While in Nome I returned a call Carrie Williams (Acting St Marys City Administrator). She asked if the Mission had any "rights" to the waste heat from AVEC. I told her that to the best of my knowledge, there are no signed and executed agreements between the Mission and AEA that would provide the Mission with any rights to the waste heat. Talso contacted Chuck Egner regarding the St Marys water system upgrade. He is interested in subcontracting with AEA to provide the design engineering for the City's WH system upgrades. Elim - Thursday 2/12/92 (25F, partly cloudy) I departed Nome on Olson Air at 10:30 am and arrived in Elim at 12:00 noon. I met with Lyle Sewartz (Principal - 890-3021) and Clarence the maintenance man and explained the operation of the waste heat system. Elementary School I inspected all valves in the High School for correct settings, installed flow direction arrows and thermometer tags, and collected as-built information. I recorded the following data: Boiler Loop: Into HXR: 150 degrees Out of HXR: 158 degrees Waste Heat Loop: Supply: 178 degrees Return: 150 degrees Pressure: 21 psi High School: Iinspected all valves for correct settings, installed flow direction arrows and thermometer tags, collected as-built information and recorded the following data: Boiler Loop: Into HXR: 158 degrees Out of HXR: 176 degrees Waste Heat Loop: Supply: 178 degrees Return: "broken" Pressure: 10 psi The glycol concentration was tested and determined to be 23% ethylene glycol with good inhibitor. Air needs to be vented from the arctic pipe between the high school and elementary school (air can be heard gurgling in the arctic pipe where it drops below ground between the two school buildings. Waste Heat Module: I again rendezvoused with Steve Flowers (AVEC Field Technician) at the power plant. Mr. Flowers indicated that a new 2-1/2" amot valve was scheduled to be installed and the power plant cooling system booster pump was to be removed. At the WHM, the valves were inspected for correct settings. All were OK except the normally open 3/4" amot bypass valve was closed. I pointed this out to Mr. Flowers and explained that the valve is designed to be open to allow some flow to the radiators at all times to prevent the radiators from being at ambient temperature. _I installed thermometer tags and collected as-built information. Position #2 (A-C 685i) was on line and carrying a load of 75 kW. The following data was recorded: Waste Heat Loop: Pressure: 13 psi Supply Temp: 178 degrees Return Temp: "missing" AVEC Loop: Into HXR: 185 degrees Out of HXR: 165 (into AMOT & Rad's) Eng Rtn: 165 degrees Prior to departing for Golovin, Luther Nagaruk (City Clerk - 890-3441) asked if there was enough waste heat available to provide heat to the City circulating water loop and the City office. the water loop passes adjacent to the power plant and the City office is about 100 feet from the power plant. I informed Mr. Nagaruk that there was not enough heat for the water loop but that there may be some available for the City office and that I would look into it and let them know. Golovin - Thursday 2/13/92 and Friday 2/14/92 (20F, clear and calm) I departed Elim at 4:45 pm and arrived in Golovin at 5:10 pm. I met with Dora Smith (City Clerk - 779-3211) and discussed their planned bulk fuel system upgrade. I collected information on tank capacities, property lines, flood information, labor and equipment availability, and other pertinent data necessary to design the bulk fuel facility. The City has not yet been notified if they will receive an RDA grant to proceed with their project. I informed Ms. Smith that regardless of additional funding sources, AEA would provide a grant of up to $20,000 for the facility engineering, design, plan review, SPCC plan upgrade,and Coast Guard Operations manual. While in Golovin, I inspected the waste heat system that provides heat to the WTP and City office. The system was installed with the help of AEA in February 1988. The system is functioning well, however, the glycol concentration is only 25% Dowfrost Propylene glycol. A mixture of 35% is required to provide burst protection to -60F. White Mountain - Friday 2/14/92 (Clear and cold) I departed Golovin at 11:30 am on Olson Air and arrived in White Mountain at 11:45 am. I met with Lucy Ashenfelter (Utility Clerk) and Tom Gray (Mayor - 638-3411) to discuss the feasibility of a waste heat system from the City power plant to the Bering Straits School District High School and Gym. According to the FMA waste heat feasibility study for White Mountain, the school buildings could receive about 10,000 gallons of waste heat. I estimated the project to cost about $90,000 if constructed using local labor. I informed Mr. Gray that the Energy Authority does not have funding to construct a waste heat system , but that I would talk with the school district to see if they are interested in funding the project. Mr. Gray would like to relocate the power plant at the other side of the community and provide heat to the City shop. He requested a "feasibility" study to determine the cost of relocating the plant. I suggested that he write a letter to AEA requesting assistance. I verified information on the school heating system and power plant. I was told that White Mountain was due to get a new school sometime in the next ten years. The location of the school and the future use of the current school are unknown. I departed White Mountain at 5:15 pm on Olson Air and arrived in Nome at 5:45 pm, departed Nome on Alaska Airlines at 6:20 pm and arrived in Anchorage at 7:45 pm. CONCLUSIONS: Savoonga: The waste heat system is working well. However, since the BSSD school consumes about five-times as much fuel as is available in waste heat, the district is not convinced that they are receiving enough benefit from the system to continue to use it. I will talk with the district and explain what is happening in Savoonga. I will also recalculate the amount of heat the district receives to determine if our WH sales agreement reflects how much heat they do get. The arctic pipe should be replaced or modified to eliminate the leaky joints (Savoonga is one of the few systems that did not have the original copper arctic pipe replaced with IC Moeller pipe), I do not suggest expending any funds in Savoonga until we can answer the districts concerns above. Elim: The waste heat system is working well. About 30 gallons of Dowtherm SR-1 needs to be added to the arctic piping system to increase the mixture from 23% to at least 30%. This will provide burst protection to the arctic piping to -60F. Also, air needs to be vented from the piping between the high school and elementary school. Golovin: Information was obtained to assist the community in the design of their bulk fuel facility. The waste heat system was also inspected and found to be working properly. The glycol mixture needs to be increased from 25% to 35% Propylene glycol to provide burst protection. White Mountain: I will contact the BSSD to see if they are interested in funding a WH project in White Mountain. Also, the City has requested a cost estimate to relocate the power plant to the other end of the City and provide WH to the City shop. /SS State of Alaska d Steve Cowper, Governor Alaska Energy Authority A Public Corporation August 29, 1989 Mr. John Oksoktaruk Utility Clerk City of White Mountain Utilities P.O.

After meeting with the city council and inspecting the module, we took off from Brevig Mission and headed for Wales. Unfortunately, low fog layers forced us to turn around at Tin City and we had to return to Nome. We spent the rest of the afternoon at the Nome Beltz school complex discussing the remote generator project with the Director of Maintenance, Mr. Poul Mercouris. 4/17: We left Nome at 9.00 a.m. and flew to White Mountain where we arrived 35 minutes later. We met with the new City Administrator, Mr. Jim Richards, who explained tous that the City of White Mountain was in the process of moving the power plant module down adjacent to the High School Generator Building. According to the plan, the. City of White Mountain would take over the school's power plant and provide power to the school as well as to the rest of the village. The school power plant was generating single phase while the city’s power plant was generating 3-phase power. Current.total loads were about 40-50 ‘kw. Mr. Richards explained that the fuel economy experienced with the new 125 kw Detroit generators was absolutely terrible. Currently only about 3-4 kilowatthours were produced per gallon of fuel consumed. ft should be considered to reconnect the , Detroit generators for single phase power and subsequently replace one of the diesel engines with .a smaller engine appropriate for the load. I promised Mr. Richards to take contact with Emerson Diesel in Anchorage to discuss this option. We left White Mountain at 3.00 p.m. and flew to Golovin, where we arrived lo minutes later. In Golovin we met with the “Utility Manager, Mr. Charles Louis who explained the current plans for upgrades to the systems in. Golovin. The purchase of anew 85-125 kw generator would be completed shortly and funding was available for the ‘installation of a small waste heat system. Mr. Louis requested that the Alaska Power. Authority provides the engineering for such a system and I promised to help as much as I could. We left Golovin at 6.30 p.m. and arrived back in Nome 30 minutes tater. 4/18: I met with the General Manager of Nome Joint Utilities, Mr. Bill McKinney at §&.00 a.m. to °discuss the proposed project at iome Beltz High School. Mr.) M¢Kinney was very enthusiastic about the project and he requested that I refine the feasibility assessment for the project. Also, Mr. McKinney mentioned that he would be interested in the Alaska Power Authority being a third party in an agreement between NJU and NSD. Both parties would be . relying on APA for technical assistance and I promised that APA could
