Tar cracking low-emission efficient biomass gasification furnace

A tar cracking low-emission efficient biomass gasification furnace relates to a gasification furnace. The purpose of the utility model is to solve the problems of unstable combustion, low heat value, impossibly complete combustion of tar, unavailable heating, inadaptability to gasification industry and incapability of meeting the requirements of users for using fire throughout the year of the existing gasification furnace. The gas guide pipe of the tar cracking low-emission efficient biomass gasification furnace is arranged on the outer sidewall of the furnace body; the upper end of the gas guide pipe is communicated with the inner space of the furnace body; one end of an oxygen feeder is arranged under the inner space of the furnace body, while the other end thereof is located outside the furnace body; a fuel processing barrel is arranged on the outer sidewall of the furnace body and located above the oxygen feeder; a plurality of hangers are arranged in a mutually staggered manner on the outside inner wall
