Technical Field

The utility model relates to a solid useless field of handling, concretely relates to solid useless processing is with burning furnace that burns.

Background

Incineration disposal is one of the main methods for solid waste disposal. The difference between the melting point and the ignition point of the material is large, when the material is incinerated in an incineration system, the material is easily melted immediately due to the influence of high temperature in the incineration system, and a material outlet is easily melted and blocked for a long time. Meanwhile, in the normal operation process of the incinerator, the inclined top of the incinerator generates ash deposit. After the operation for a period of time, the accumulated ash on the top of the inclined furnace affects the gas circulation inside the top of the inclined furnace, and finally affects the normal operation of the incinerator.
