    11/06/2008· Re: Coating formation in Kiln Inlet. Hi. Coating at kiln inlet ia mainly due to the volatiles like Chlorides, alkalies ( Na2O and K2O) and SO3. To minimise the coating formation, the alkali sulfate ratio should be around 1.1 so that these volatiles will come out as alkali sulfate along with the clinker so that the recirculation inside the kiln circuit will be less.
