Boiler classification
Classified by slag discharge method
Solid-state slagging boiler: The ash generated after fuel combustion is discharged in solid form, which is the main slagging method for coal-fired boilers.
Liquid slagging boiler: The ash generated after combustion of the fuel flows out of the slag mouth in a liquid state, and is cracked into small particles in the cooling water of the cracking tank to be discharged into the ditch.
