specific heat consumption cement kiln

Cement kiln dust is a major waste to the air environment and needs collection and disposal to protect the surrounding air. Kessler 1995 reports that typically each percent of dust wasted increases the specific heat consumption by about 0.7 and decreases clinker production by 0.5. He gives the dust losses costs as Cwtl 4.08ton of cement ...

    Different Possible Ways for Saving Energy in the Cement

    In terms of absolute consumption, the cement industry occupies a front position in the ranks of energy consumed industries. The total energy costs thermal and electrical make up about 30 to 40 percent of the total production costs of cement. This is why efficient energy utilization has always been a matter of priority in the cement industry.
