Assam coal containing 2-6% sulfur and around 40% volatiles can be used for making quality cement in the black meal process for cement manufacture using the Vertical Shaft Kiln (VSK) technology. It is observed that the use of these sulfur bearing fuels need little modification in the operational parameters of the VSK. The chemical, mineralogical and physical properties of the clinker/cement produced using Assam coal as fuel in the above process are provided. The clinkers generated with sulfur bearing coals are studied and probable reasons for obtaining quality cement even with an SO[sub 3] content of more than 3% in the clinkers are discussed.
