The preheater/precalciner systems are compared with systems with preheaters only. It was observed that the dust emissions of preheater/precalciner are much lower than that of preheater process. The preheater process has 5.4 times higher PM emissions than preheater/precalciner process in the U.S.A. In Turkish cement "* plants, this ratio is 4.3.
