Abstract
The invention relates to a method for retrofitting an incineration grate (10a, 10b) of a waste incineration plant by integration of a separating grate (11) allowing separation in fine and coarse slag, comprising the steps of a) removing a downstream end section (22) of the incineration grate, wherein a main section (31) of the incineration grate remains in place, b) providing a support structure configured to support a separating grate (11) and connecting the support structure to a support frame (28) of the incineration grate, c) arranging the separating grate on the support structure, which separating grate comprises grate elements (49) and has openings (46) for ejecting fine slag, wherein the separating grate has in certain regions air feeds (45) that are distributed over its entire width for the controlled supply of air to the slag, and the air feeds (45) are isolated from the openings (46) and formed separately.
