METHOD OF PROCESSING THE COMBUSTION PROCESS RESIDUES FROM THE COMBUSTION PLANT

摘要

Typically 1000 kg of rubbish including 220 kg of incombustible material may be burnt on a grate. 800 kg of flue gases are produced. 100 kg of recirculated fine ash is added to the fuel bed. 300 kg of ash is removed from the fuel bed and washed with water producing 315 kg of wet material. This is sieved producing 215 kg of coarse fraction and 100 kg of fines for recirculation. Some of the fines may be removed for other uses. The coarse fraction is made of particles of diameter greater than 8 mm. 1000 liters of wash water from the ash from the fuel bed is circulated through the coarse material and removes and picks up 15 kg of fine particles and is recirculated. 40 liters of top-up water may be added. The coarse material is discharged after washing.
