Description:
The report gives results of a gasification pilot program using two biomass feedstocks: bagasse pellets and wood chips. he object of the program was to determine the properties of biomass product gas and its suitability as a fuel for gas-turbine-based power generation cycles. he feedstocks were gasified at a feed rate of approximately 1 ton/hr (907 kg/hr), using a GE pressurized, fixed-bed gasifier and a single stage of cyclone particulate removal, operating at 538 C. The biomass product gas was analyzed for chemical composition, loading, fuel-bound nitrogen (FBN) levels, and sulfur and alkali content. oth feedstocks gasified easily. he composition and heating value of the biomass product ga s were compatible with gas turbine combustion requirements. owever, the particulate removal performance of the pilot facility single-stage cyclone did not meet turbine specifications. n addition, alkali metal compounds in the particulate matter (at 538 C) carried over from the gasifier exceeded turbine limits. mproved particulate removal technology, designed specifically for biomass feedstock characteristics, could meet turbine requirements for both particulate and alkali loading. BN compounds were also measured since they can be converted to nitrogen oxides (NOx) during combustion in a gas turbine.
