Based on the analysis of the characteristics of the updraft and downdraft fixed bed biomass gasification device, a compound low-tar biomass gasification fixed bed device was proposed, and a medium trial scale test device with a treatment capacity of 600 kg/h of biomass was established and studied. The results show that the compound low-tar biomass gasification fixed bed device has the advantages of simple structure, high gasification efficiency, high thermal efficiency, high carbon conversion rate, wide applicability of raw materials, and greatly improves the level of gas cleanliness. It has played a great role in promoting the industrial application of biomass gasification, power generation, heating, and fossil fuel substitution.
