小型廃棄物ガス化発電システムのガス化・発電特性(オーガナイズドセッション1 バイオマスエネルギー変換)

Abstract

The gasification system investigated in this research is a two-stage gasification system composed of a shaft type gasification furnace and a reforming furnace. The electric power is generated by a dual fuel type diesel engine. In the experimented, mold bed wastes are used as fuels and the attention was paid to the following three parameters; the sample form, the steam injection effect from the bottom of the gasifier, and the kind of the reforming agent. The influence of these parameters on the composition and the heating value of the generated gas was investigated. The experimental results show that suitable sample form for this system is the pellet form and the steam gasification reaction in the gasification furnace was promoted by injecting steam into the gasification furnace. The heating value of the reformed gas increase 30% or more by using oxygen instead of high temperature air as a reforming agent. The energy rate of the reforming gas supplied to the engine reached as high as 89.6% when oxygen was employed as a reforming agent.
