The storage plate is installed on the side end of the slider, and the collecting plate is arranged inside the gasifier. When the gasifier is in use, the fume treatment device of the gasifier forms a closed space inside the gasifier by closing the hinged door, so that the inside of the gasifier gradually rises, which is convenient for secondary combustion. By driving the handle on the front of the storage plate, the storage plate is pulled out of the gasifier. In this process, the movement of the storage plate will drive the slider inside the slide to slide together, which is convenient for adding combustion raw materials. When the combustion raw materials are burned to a certain extent, they will become powdered waste, which will fall into the collection plate through the discharge hole, which is convenient for centralized treatment of waste.
