The Electric Power Research Institute and the Tennessee Valley Authority have developed an extensive program investigating cofiring woody biomass in pulverized coal and cyclone boilers with emphasis on meeting the needs of customers while reducing emissions of carbon dioxide from fossil combustion. The program has developed detailed data concerning the fuel chemistries of the wood, coal, and multi-fuel blends at the Allen Fossil Plant and the Kingston Fossil Plant. The program has developed additional data concerning the performance of wood/coal blends in pulverizers, in bunkers, and in the cyclone and PC boilers of TVA. This paper reviews the results of the EPRI/TVA cofiring program to date including: specific characteristics of the coal and biofuels at TVA power plants, the results of design studies, and the economics of cofiring woody biomass in TVA boilers. At the same time, the paper reviews some of the constraints on cofiring, including issues associated with wood fuel preparation and handling, boiler efficiency, and emissions control.
