Use of Alternate Fuels in the Cement Industry - nbmcwCement - Wikipedia

Coal is the basic fuel used in the Indian cement industry While it mainly provides the requisite heat and temperature, the ash content in the coal also combines chemically with the limestone to help form cement clinker In India, coal will, of course, continue to be the dominant fuel for a very-long timeA cement plant consumes 3 to 6 GJ of fuel per tonne of clinker produced, depending on the raw materials and the process used Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil.
