The two¬stage downdraft gasifier is a potential type of gasifier, which is suitable for distributed power system of biomass gasification and with merits of low tar content in syngas. In order to investigate the effects of rice straw char bed on the nascent tar removal, a lab¬scale two stage hot rod reactor was constructed. The nascent tar was produced in the first stage by pyrolysis of rice straw at 500°C. With the consistent input nascent...
