Abstract

Method for incineration of the remaining solids that are burnt from a chemical plant, which includes Slurry feeding of residual combustible solids in oil, oil content of at least 0.5% by wt. By weight of residual combustible solids. Enters the burner in the combustion furnace Consisting of a back combustion chamber with a burner in the upper part of it The second-class combustion chamber is present in the lower part of the main combustion chamber. And the discharge gas pipe is located underneath And connected to the second combustion chamber, residual combustion in the main combustion chamber, conduction of combustible gas Into the second floor combustion chamber And letting it sit at 800 to 1000 ํ C for at least 0.5 sec.

Claims (1)
