No.23 Production of Carbonized Woody Biomass for Co-combustion Use in Coal Fired Power Plant

Abstract

Woody biomass co-combustion in coal fired power plant is one of effective measures to reduce CO_2 emission, but the grindability of woody biomass and coal are very different. Then it is difficult to increase the biomass mixing ratio with coal. The carbonization technology make it possible to upgrading the grindability, heat value of woody biomass. In this study, carbonization tests were carried out in 4 t/d test facility to obtain the carbonization performance. As the result, it is clear that a yield of carbonized biomass is a useful operation index in carbonization process.
