  • Coal in the cement industry

    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 In direct firing system, coal is milled on line and is directly fed to the kiln The primary air is used to dry the coal High moisture coal is not suitable for· What role does coal play in cement production? Coal plays a very important role for manufacturing plants is undeniable In many applications from gasification technology, liquefaction, production of chemicals, the role of a fuel in the production process is the most prominent and important Therefore, it is impossible not to mention the use of coal in the cement production process – one ofCoal and its application in the cement production processon coal and petroleum coke to fuel the kilns for clinker production Globally, CO2 emissions from cement production were estimated at 829 MMTCO2 in 2000 7, approximately 34% of global CO 2 emissions from fossil fuel combustion and cement production In addition to combustionrelated emissions, cement production also is a source of processrelated emissions resulting from the release of CO2CO2 Emissions Profile of the US Cement Industry
