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.
A method comprising processing slag occurring in a combustion chamber of a refuse incineration plant that is produced by the refuse that is burned on an incineration grate and at the same time conveyed in the direction of a slag removal device, wherein:
An incineration grate, comprising a plurality of grate elements, which rest one upon the other in the manner of steps in a conveying direction of refuse to be burned and thus form grate steps, wherein the incineration grate is designed as a separating grate, at least in the end region thereof situated downstream in the conveying direction, which separating grate has openings configured to separate a fine fraction of the slag from a course fraction of the slag and eject the fine fraction, wherein the separating grate has at least in certain regions air feeds that are distributed over its entire width for the controlled supply of air to the slag, and the air feeds are isolated from the openings and formed separately.
A combustion chamber for a refuse incineration plant comprising an incineration grate, wherein:
