1-14　Co-combustion Behaviors of Woody Biomass with P ulverized C oal

Abstract

Currently, the proportion of fossil fuel in the primary energy supply in Japan is very high. So, the use of renewable energy is collecting a lot of attention as an alternative to fossil fuel. Biomass, a type of renewable energy, has the advantage of carbon neutral. On the other hand, Biomass has the disadvantage of low power generation efficiency when using power generation because of the low energy density. From these backgrounds, biomass co-combustion for coal fired power generation has been focused on. In this study, co-combustion experiments of pulverized coal and biomass samples were carried out, in order to investigate the effect of mixture ratios and types of biomass samples on co-combustion behaviors.
