Abstract
The utility model discloses a biomass tubular entrained-flow bed gasification system which comprises a first gasification furnace, a second gasification furnace, a third gasification furnace and a combustor, a raw material inlet, a gasifying agent inlet and a carrier gas inlet are formed in each of the first gasification furnace and the second gasification furnace; first outlets of the first gasification furnace and the second gasification furnace are connected with a first inlet of the third gasification furnace; by utilizing the combination of a plurality of tubular gasifiers, the conversion efficiency of biomass resourceful treatment is improved, and meanwhile, gradient utilization of energy is realized through reasonable waste heat recovery. Compared with an existing gasification furnace, on one hand, steam gasification of biomass can be achieved in an external heating mode, the heat value of produced gas and the conversion rate of raw materials are remarkably increased, on the other hand, gradient utilization of energy can be achieved in a sleeve heat exchange mode, and therefore the energy efficiency of the whole process is improved; the technical problems of low raw material conversion rate and low energy efficiency of the gasification furnace in the prior art are solved.
