ENERGEO, Inc. is engaged in a demonstration test program of its AGRIPOWER 200 unit fueled with biomass at Sutton Lumber Company in Tennga, Georgia. The objective of the program is to evaluate the operating and performance characteristics of the system using lumber wastes for fuel. The program is scheduled to accumulate 8000 hours of operation over a period of 1 to 2 years. The program became a reality due to initial funding from the U.S. Department of Defense (DoD`s) Strategic Environmental Protection Agency`s (EPA`s) Air and Energy Research Laboratory (AEERL). The AGRIPOWER unit operates with an {open_quotes}open{close_quotes} Brayton cycle using a fluid bed combustor and several heat exchangers to heat compressed air which in turn drives a turbine/generator (T/G) set. The T/G set, which includes the compressor and a recuperator, is a Solar {open_quotes}Spartan{close_quotes} unit packaged for this application by Alturdyne, Inc. The combustor utilizes both in-bed and freeboard combustion zones, and the above-bed zone is well mixed to provide uniform temperatures. Design specifications call for consumption of 612 lb/hr (278 kg/hr) of fuel with a heating value of 5,270 Btu/lb (12,248 kJ/kg). The net electrical output will be approximately 200 kW-hr/hr. This corresponds to a heat rate of 16,130 Btu/kW-hr (17,001 kJ/kW-hr). The capital cost of an AGRIPOWER 200 unit will be approximately $2,250/kW of capacity.
