This invention relates to the field of
biomass gasification furnace technology and discloses a feeding structure for a
biomass gasification furnace, including a furnace body. A feed lifter is located on one side of the furnace body, and an upper feed
pipe is located on one side of the top of the furnace body. The upper feed
pipe is positioned below the top end of the feed lifter. The feed lifter raises
biomass fuel and feeds it into the furnace body through the upper feed
pipe. An
auger shaft is located inside the furnace body, and spiral blades are fixedly installed on the
auger shaft. A
discharge channel is located at the top of the furnace body, and an upper sealing plate and a lower sealing plate are installed within the
discharge channel. The upper and lower sealing plates alternately block the
discharge channel during feeding. By alternately blocking the discharge channel with the upper and lower sealing plates, when the upper sealing plate opens, the lower sealing plate is in a blocked state; when the upper sealing plate closes, the lower sealing plate opens. This ensures that the gasification furnace is always isolated from the outside environment, achieving
continuous feeding of the gasification furnace without leakage.
