Abstract
The invention discloses a biomass horizontal pyrolysis gasifier. The structure of the biomass horizontal pyrolysis gasifier comprises a furnace body (1), a feed inlet (8), a gas nozzle (9), an air inlet (5) and an ash discharge opening (7). The feed inlet is arranged at the rear end of the furnace body. The furnace body (1) is a sandwich structure, wherein an inner cavity of the sandwich structure is a gasifying chamber (11), and the middle part of the sandwich structure is an air inlet chamber (12). The feed inlet (8) and the gas nozzle (9) are communicated with the gasifying chamber. The air inlet (5) is communicated with the air inlet chamber (12). The bottom of the furnace body is provided with a feed delivery mechanism (4). The gasifying chamber (11) and the air inlet chamber (12) are communicated with each other at the position of the feed delivery mechanism. According to the biomass horizontal pyrolysis gasifier, by introducing cold air into the air inlet of the sandwich structure, the furnace wall and a reciprocating grate are cooled, and heat-absorbed hot air also can flow upwards from the bottom of a feed layer through the reciprocating grate. By an up-to-bottom counter-burning mode, the feed layer will not be overlapped or mixed during operation of the reciprocating grate, multiple tower-type feed layers are formed to undergo continuous pyrogasification, and safe and stable operation can be carried out on the grate.
