[0002] With the long-term operation of Jinhua furnace, the steam of waste boiler decays, and the waste boiler tube screen is seriously slag-hanging. Once the coal type changes or the furnace condition fluctuates, hard lumps will fall and block the lock bucket. The gasifier is operated at reduced load to poke slag, which is seriously forced to stop the furnace. This problem seriously affects the operation of the gasifier. The slag-poking process causes unnecessary waste of manpower and material resources, and causes the gasifier to operate at low load. Therefore, it is considered to add water spraying technology at the slag outlet of Jinhua furnace to reduce the slag hanging on the waste boiler wall.

[0004] The comparative document shows that the device of the present invention can collect and clean the fuel residue on the furnace wall, and the powdered fuel residue can be mixed and stirred by the mixture and clean water, which is easier to collect and process without causing fly ash to spread. The collection mechanism can more efficiently and comprehensively collect and clean the fuel residue on the furnace wall, the extrusion mechanism can continuously squeeze the mixture and clean water to mix with the falling fuel residue, and the stirring mechanism can more conveniently process the fuel residue and effectively prevent fly ash.
