NOVELTY - A high-temperature low tar biomass gasification device has feeder (15), gasification stove (11), tar catalytic cracking reaction cylinder (19), and heat exchanger (20). The gasification stove is set as sleeve structure by internal cylinder (2) and external cylinder (1) with annular cavity formed inside the cylinders. The internal cylinder has pre-heating hopper (3) hanging on lower end surface of stove top (17) and connected with the feeder. A bottom part of the internal cylinder is a residue storage chamber (10).    USE - A high-temperature low tar biomass gasification device.    ADVANTAGE - The device does not use external heat source; and has a structure that is simple and compact. It provides improved heating value and gasification efficiency, and reduced tar content.    DETAILED DESCRIPTION - High-temperature low tar biomass gasification device comprises feeder (15), gasification stove (11), tar catalytic cracking reaction cylinder (19), and heat exchanger (20). The gasification stove is set as sleeve structure by internal cylinder (2) and external cylinder (1) with annular cavity formed inside the cylinders. The internal cylinder has pre-heating hopper (3) hanging on lower end surface of stove top (17) and connected with the feeder. A bottom part of the internal cylinder is a residue storage chamber (10). The annular cavity is used as gasification agent pre-heating cavity. An inlet (18) of the gasification agent is connected with the annular cavity. An outlet of the annular cavity is an air port (9) set on side wall of the residue storage chamber. Flue gas generated in the internal cylinder enters into the tar catalytic cracking reaction cylinder through fuel gas outlet on top part of the internal cylinder. A heat exchange media in the heat exchanger is the generated fuel gas from the tar catalytic cracking reaction cylinder and cold gasification agent to be pre-heated. A gasification outlet (24) of the heat exchanger is connected with the inlet of the gasification agent in the gasification stove.
