how much fuel does a cement kiln use

Dec 31, 1996 Dec 31, 1996 The use of scrap tires as a supplemental fuel in the United States Portland cement industry has increased significantly in the past six years. In 1990, there were two kilns using tire-derived fuel (TDF), today 30 kilns use TDF. The outlook for continued and expanded use of TDF in the U.S. cement industry should be considered favorable, with 15

    Cement manufacturing is an energy-intensive process due to the high temperatures required in the kilns for clinkerization.

This means that 6 tph of ashes are integrated into the 200 tph sintering material. Through this process, both the thermal and mineral value of waste is to 100% utilised by the cement kiln

    After this, and brief flirtations with natural gas, coal became emphatically the cheapest kiln fuel from the mid-1970s, and newer kilns had to be retro-fitted with coal grinding equipment. Since then, coal has remained the main fuel, although partially - and at some plants totally - displaced by Petcoke
