The Pat. No. 6,142,771, entitled "Control of cement clinker production using high sulfur fuel in a LelepLepol travelling grate rotary kiln by analysis of sulfur in the end product" issued to Joseph Doumet on Nov. 7, 2000, describes a method and apparatus of producing cement clinker using a highsulfur content fuel.
Results of a study conducted in an operating plant will be used to compare the changes observed in the grinding department as well as analyze the effects on cement quality and document the improvements and detriments when clinker with various excess sulfur levels is produced.
A pilotscale trial was undertaken in a 7·4 m kiln to demonstrate the production of belite calcium sulfoaluminate cement clinker using sulfur as a raw feed. The sulfur was introduced in its elemental form as fuel to the burner, thus partially offsetting fuel costs while providing sulfur trioxide which is incorporated in the clinker.
