Abstract

The invention relates to a system and a method for producing cement clinker from raw meal. According to the invention, the raw meal is preheated in a preheating zone, is precalcined in a calcination zone, is burned in a sinter burning zone, and is cooled in a cooling zone while solid combustibles are burned in an additional burning zone in which a firing area is used, the solid combustible being introduced into the firing area and forming a combustible bed therein over which a delivered oxygen-containing gas flows, the obtained combustion products being discharged via a discharge port and being utilized during the production of cement clinker. The combustible is delivered via a conveying device located outside the firing area so as to move the existing combustible bed in the direction of the discharge port.
