Coal for cement: Present and future trends

Coal Overview

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.

Gravimetric and Volumetric Coal Feed Systems for Boilers

The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.
