Wood-Fired Cogeneration System for University of California, Santa Cruz. Final Report

摘要

An innovative design of wood-fired cogeneration to meet the needs on the campus at the University of California is described. It is an open-cycle, indirectly-fired gas turbine with heat recovery in the exhaust stack. There is in addition an auxiliary system turbine to make use of the heat not required in the summer months. The system incorporates a fluidized bed combustor to achieve high combustion efficiency and low overall pollution. The system can be assembled from readily available components. The system will deliver a net efficiency of 83%, with 28% of the wood energy being converted to electricity and 55% being converted to recovered heat. It will provide 2.4 Megawatts of electricity and 5.3 MW (18 million Btu per hour) of heat for buildings and hot water. The main environmental constraints are air quality and noise, and it appears that this system can be fitted to the prevailing standards. (ERA citation 06:018830)
