Impact of ALKALY, SULPHURE and CHLORINE in Kiln operation ,

If sulphur is very high and is not balanced by alkalis, it will also continue to recirculate within the kiln/preheater system and increase the probabliity of kiln rings and preheater buildups Excess sulphur in the hot meal can also form sulphospurrite (2(CaO)SiO2CaS04) in the middle cyclones, which forms exceedingly hard and dense buildups which can take a long time to remove...
