Alternative Fuels in Cement Manufacturing | IntechOpen

2011/08/09 · Worldwide, coal is the predominant fuel burned in cement kilns. Cement production consumes approximately 120 kg of coal per tonne of cement. In the European Union about 25 million tonnes of coal is required annually by the Cembureau - members to service the demand of …

Gas Fuel Rotary Kiln Use Coal Gas, Liquefied Petroleum Gas

The calorific value of natural gas is not as high as that of liquefied petroleum gas, but in some countries with abundant natural gas reserves, cement rotary kilns used in cement production mostly use natural gas as the main fuel. Natural gas can replace oil fuel and raw coal as the main fuel of rotary kiln.

A feasibility study of using carbon black as a substitute to coal

2013/06/01 · Cement factories traditionally use coal as an energy source in cement kilns since coal gives the high temperature that is required. Cement manufacturing is an energy intensive process. The extensive use of coal in kilns makes cement factories sensitive to rising prices of fossil fuels, and so an alternative fuel is needed to reduce fuel costs.

Fire and Explosion Hazards in Cement Manufacturing Industries

Coal is often the main fuel source used to heat the cement kiln. Coal pulverizers are required to grind the coal from the bulk storage size to a smaller particle diameter to use in the kiln. Coal pulverizers significantly reduce the mean particle size of the coal, drastically increasing the fire/explosion hazard risk.
