Dept. of Energy. Geothermal Division ; distributed by the Office of Scientific and Technical Information, U.S. Dept. of Energy PP Washington, D.C; Oak Ridge, Tenn. YR 1978 AB Digital computer simulation was used to investigate the peak, steady energy utilization of a geothermal energy-supported dairy. A digital computer program was also written to assess the lifetime economics of the dairy operation. A dynamic simulation program was written to design water storage tanks under diurnal transient loading. The geothermal site specified is the artesian spring named Hobo Wells near Susanville, California. The dairy configuration studies are unique, but consist of conventional processing equipment. In the dairy, cattle waste would be used to generate methane and carbon dioxide by anaerobic digestion. Some carbon dioxide would be removed from the gas stream with a pressurized water scrubber to raise the heating value. The product gas would be combusted in a spark ignition engine connected to an electric generator. The electrical power produced would be used for operation of fans, pumps, lights and other equipment in the dairy. An absorption chiller using a geothermal water driven generator would provide milk chilling. Space heating would be done with forced air hot water unit heaters.
