[Abstract] Biomass gasification power generation technology is an effective way to utilize biomass energy, and it is being widely studied and used increasingly. However, in the use of biomass gasification power generation technology, there are problems such as biomass material transportation, storage, combustion and coking, generation of coke-containing wastewater, and difficult recovery of tail gas, so further research is needed. The use, existing problems and future development direction of biomass gasification p
