In the present study, authors focus attention on biomass gasification for small or medium scale electricity generation(several hundred to several thousand kW). The main problem in biomass gasification is to realize an economical yet high-conversion process reducing tar formation in the downstream section. Waste house brick was crushed and used as bed material for steam gasification of biomass. Our previous results showed that tar was absorbed on the crushed clay brick and gasification was promoted by iron contained in it. The pilot scale gasifier with a riser type circulating fluidized bed having large volume in its bottom section (height:3.5m, diameter:36.7mm) was used. Continuous biomass gasification experiments were carried out. Effects of particle hold up and gas velocity in the riser, gas velocity in the bubbling zone and feed rate of biomass on tar generation, gas conversion and cold gas efficiency were examined.
