Use of the alternative fuels in the cement industry

2017-11-9 · Use of coal during production of cement . Coal is fuel sediment which consists of products of disintegration of plants. Process of creation of coal is based on increase of relative content of carbon (C) and decrease of content of oxygen (O. 2), of nitrogen (N. 2)

Which type of coal use by cement industry.

Coal is only used for burning the klin to 1400°c to produce the concrete. The other method to produce concrete is by fly ash. Which again is not coal but a by product of burning coal which flies out and is collected using electrostatic precipitation. So whatever coal floats your boat to reach 1400° or to make fly ash will serve the purpose.
