Abstract

The present disclosure provides a method and a sensor device for evaluating residual Sulphur in a cement preheater of a cement kiln, wherein the residual sulphur is based on the values of the fuel sulphur content, the fuel rate of consumption, the hotmeal quality and the clinker sulphur content. The present disclosure further provides a method for evaluating blockage in a cement preheater, including evaluating the residual sulphur in the cement preheater, determining an agglomeration rate of sulphur compounds agglomerating on an inner surface of the cement preheater based on the residual sulphur, and evaluating a level of blockage in at least one predetermined pathway of the cement preheater using a blockage evaluation unit, wherein the level of blockage is based on the agglomeration rate.
