Cement Kiln Combustion Exhaust Diagram

The main physicochemical processes taking place in the calciner are coal combustion and the strongly endothermic calcination reaction of the raw materials In this paper a numerical model and a parametric study are presented of the flow and transport processes taking place in an industrial calciner
