Coal in the cement industry
2012-11-8 The main fuel used for firing preheater cyclone and rotary kiln is coal. Therefore, coal plays an important role in the manufacturing process of cement. Based on the composition of raw feed a wide range of coal is used. In a cement plant two systems of coal firing are used, namely, a) Direct firing and b) Indirect firing.

Use of Alternative Fuels in Cement Manufacture: Analysis ...
2019-12-31 Worldwide, coal is the predominant fuel burned in cement kilns. Global energy- and process-related carbon dioxide (CO 2) emissions from cement manufacturing are estimated to be about 5% of global CO2 emissions (Metz 2007). Cement is made by combining clinker, a mixture of limestone and other raw materials that have been pyroprocessed in the cement kiln, with gypsum and other cementitious additives. Clinker production

Alternative Fuel Use in Cement Manufacturing
2016-4-4 Alternative Fuel Use in Cement Manufacturing 6 1.2 Emissions from cement production More than 50% of the total CO2 from cement production results from the chemical reaction that converts limestone into clinker, the active ingredient in cement. This chemical reaction accounts for approximately 540 kg CO2 per tonne of clinker.
