AI Technical Summary
In existing biomass gasifiers, slag such as stones, tiles, and broken glass bottles tend to accumulate on the air distribution plate, obstructing air intake and affecting the normal operation of the gasifier.
Design a perforated, tiltable air distribution plate for slag discharge. The plate is tilted up and down by a tilting shaft, which causes the slag to fall to the bottom of the air inlet box. The plate is cleaned regularly by a ash collection plate, and a limit rod is used to prevent the tilting shaft from tilting on its own.
Effectively removes slag from the air distribution plate, ensuring normal air intake for the gasifier and improving the stability and efficiency of gasifier operation.
