Study On Co-gasification Characteristics Of Coal And Biomass Blends

Biomass is a renewable energy. Co-gasification of coal and biomass blends can not only take full advantage of renewable energy, reduce the use of fossil energy, but also improve the utilization efficiency of coal and biomass fuels, reduce the emission of pollutants. In this paper, thermal gravimetric analysis was used to investigate the CO2 gasification rule of Yangquan coal, sawdust, wheat straw and the coal and biomass blends at the conditions of different heating rate and different coal and biomass blends inverse proportion. Comparison was made among three kinds of dynamics models, uses the best one which fits for the actual chemical experiment, and discusses the co-gasification characteristic of coal and biomass blends.
