When the inspection cover is opened, it is convenient to take out unburned objects on the mesh plate 11. An igniter 2 is fixedly installed at the mounting pipes arranged parallel to each other on one side of the combustion furnace shell 1, a motor 3 is provided on one side of the lower end of the combustion furnace shell 1, an ash hopper 4 is fixedly installed at the lower part of the combustion furnace shell 1, and an ash discharge valve 5 is installed at the lower end opening of the ash hopper 4.

[0016] In this embodiment, combined with the Figure 2As shown, mesh plates 11 are fixedly installed side by side in the upper and lower parts of the combustion furnace shell 1. The mesh plates 11 are made of steel, and the diameter of the mesh holes of the upper mesh plates 11 is larger than the diameter of the lower mesh plates 11. The mesh plates 11 and the igniters 2 are arranged alternately. A rotating blade 12 is arranged on the upper part of each mesh plate 11. A box body 13 is arranged on the lower side of the combustion furnace shell 1. A driving bevel gear 16 and a driven bevel gear 15 that are meshed and connected to each other are arranged in the box body 13.
