| 摘要 |
The present invention relates to a method for processing slag occurring in a furnace (2) of a refuse incineration plant that is produced by the refuse that is to be burned being burned on an incineration grate (10) and at the same time transported in the direction of a slag-removing device (17). The method is characterized in that the incineration grate (10) is formed at least in its end region that is facing the slag-removing device (17) as a separating grate (11), which has openings (46a-d), via which the furnace (2) is connected to a fine-slag discharge chamber (34; 34a-f), and at least one fine fraction of the slag is ejected through the openings (46; 46a-d) into the fine-slag discharge chamber (34; 34a-f) and discharged to the outside in a substantially dry state, and the remaining coarse fraction is fed to the slag-removing device (17) and discharged to the outside. 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 invention is characterized in that the separating grate (11) has at least in certain regions air feeds (36) that are distributed over its entire width and via which air is fed in a controlled manner to the slag, and the air feeds (36) are isolated from the openings (46; 46a-d) and formed separately. |
