Background

The boiler is an energy conversion device, the energy input to the boiler comprises chemical energy and electric energy in fuel, and the boiler outputs steam, high-temperature water or an organic heat carrier with certain heat energy. Boilers are generally classified into coal-fired boilers, oil-fired boilers, gas-fired boilers, and the like according to the difference in the fuel used. The raw materials used by the coal boiler are generally lump and granular raw coal with large capacity. When the coal cinder is used, solid coal is conveyed into a hearth through the conveying chain to be combusted, and combusted coal cinder is discharged for post-treatment.

The existing boiler usually adopts a slag collecting box which is communicated with the boiler through a slope section as described in a Chinese patent 'boiler dry slag discharging system' with the publication number of CN112555872A for collecting slag. Although effective slag tapping can be guaranteed in the mode, due to the fact that a certain distance exists between a slag outlet of the boiler and the slag collecting box, a large amount of coal slag is easily blocked in the slope section after being discharged into the slope section, and the coal slag discharged from the boiler contains solid residues and a large amount of dust, and easily escapes to the surrounding environment to cause pollution.
