The engineering application of biomass gasification and catalytic gasification in conical fluidized gasifier was discussed. The results showed that the heating value of gas produced by gasification of wheat straw was higher than that of rice straw and rice husk, and the calorific value of gas produced by sawdust gasification was the highest. Under non-catalytic gasification conditions, the calorific value of gas produced by fluidized bed gasification The calorific value of the gas generated by the desorption gasifier is increased by about 40%. The catalytic gasification test shows that CaO can obviously increase the calorific value of the gas and reduce the CO component. The catalytic gasification of Na2CO3 can increase the content of H2. However, the gas calorific value of gasification, fluidized air gasification, in the low temperature below 710 ℃, no significant effect, when the temperature reaches 80 0 ℃, the addition of catalyst can significantly increase the calorific value of the gas
