Cement Kilns: Precalciner kilns
The design avoids the constraints suffered by the air-though design; the combustion air for the calciner by-passes the kiln, so that high gas velocity and flame dilution are avoided. The proportion of fuel that can be efficiently burned in the calciner rises to about 70% (for ordinary blended rawmix feeds).
