Abstract
A method processes slag occurring in a combustion chamber. An incineration grate is formed at least in its end region that is facing the slag-removing device as a separating grate, which has openings, via which the chamber is connected to a fine-slag discharge chamber, and at least one fine fraction of the slag is ejected through the openings into the discharge chamber and discharged in a substantially dry state, and the remaining coarse fraction is fed to the slag-removing device and discharged. In this case, the average particle size of the at least one fine fraction is smaller than the average particle size of the coarse fraction. The separating grate has at least in certain regions air feeds that are distributed over its entire width and via which air is fed in a controlled manner to the slag, and the air feeds are isolated from the openings and formed separately.
