    Behaviour Of Volatile Materials In Cement Kiln Systems

    Abstract. Factors governing behaviour of minor amounts of Cl K Na and S in cement production kilns are reviewed. Recirculating loads form as a result of partial volatilisation in the burning zone and are often implicated in formation of build-ups coating and blockages in cooler parts of the process

    Feb 11 2009 Sulphur not combined with alkali is more damaging to kiln operation than sulphate compounds such as K2SO4 and Na2SO4. In the right proportions alkali can combine with sulphur and becomes built-in in the clinker minerals resulting in low evaporation factors. Sulphur in excess will form the more volatile CaSO4 which has a high evaporation factor
