Cement Kilns: Precalciner kilns

The precalciner system is a suspension preheater in which, in addition to the kiln flame, extra fuel is burned in the base of the preheater. The first kilns of this kind operated in Japan in the late 1960s. These systems allow more thermal processing to be accomplished efficiently in the preheater.
