Product analysis from the operation of a 10 ton/day, direct, fluidized bed, biomass gasifier and HGCU system

A principal goal of the DOE Biomass Power Program is the development of advanced high efficiency electric power generating cycles, such as integrated gasifier-gas turbine-generator systems. A key technical development required to economically produce electric power with an integrated gasifier-turbine system is the ability to remove chars and alkali metals from the gasifier product gas stream, to protect the turbines, and do so at high temperature and pressure. Westinghouse hot gas cleanup (HGCU) technology, based on ceramic membrane candle filters, has been selected for validation in this application. The HGCU system was tested at the 10 ton/day scale, using a direct, pressurized, fluidized bed gasifier. Two tests were conducted at the Institute of Gas Technology (IGT) RENUGAS process development unit (PDU) in Chicago, IL, during the weeks of October 31-November 5, 1994 and February 5-11, 1995. The overall objective of the Westinghouse/IGT HGCU performance test program was to evaluate the performance of the hot gas filters with a dust-laden product gas generated from the gasification of bagasse in the RENUGAS PDU. This filter performance information will be used to determine the HGCU operating conditions for subsequent extended testing of the hot gas filters installed in a slipstream from the 100 ton/day bagasse demonstration gasifier in Hawaii. Initially there was concern that tars produced in the gasifier would undergo coking reactions within the ceramic candles, leading to irreversible plugging of the filters. Consequently, a tar-cracking reactor was designed and installed ahead of the HGCU to remove the tars.
