Method and apparatus for incinerating combustible waste in cement clinker production process

The invention relates to a method for incineration of combustible waste during the manufacture of cement clinker. The waste is incinerated in a separate compartment, the exhaust gases produced during the waste incineration process being vented to the preheater for heating the cement raw meal, the waste is introduced via a waste inlet onto a supporting surface incorporated in the compartment and in that, during incineration, the waste is transported through the compartment to the outlet of the compartment along a circular path, characterized in that the compartment is arranged at a distance from said calciner or a preheater tower by means of a material chute, said material chute enters a downward sloping duct, said duct carries exit gas from said compartment and non-combustible material from waste fuel firing in said compartment down into the calciner or preheater tower.
