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

The waste fuels used in cement kilns are prepared either off-site by the supplier and in a form suitable for use direct in the kiln, or are prepared or treated on-site by the cement company. The types of solid waste fuels used are generally homogeneous in nature, as fuel consistency is crucial to the process when directly firing solid

    Jan 12, 2015 Jan 12, 2015 For such a kiln the fuel mix (both coal and waste derived fuel) might be around 30 tonnes per hour (tph) and produce some 20% ashes. 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

    May 09, 2012 To produce cement, limestone and other clay-like materials are heated in a kiln at 1400 C and then ground to form a lumpy, solid substance called clinker; clinker is then combined with gypsum to form cement. Cement manufacturing is highly energy- and emissions-intensive because of the extreme heat required to produce it

    The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter

    The cement industry worldwide is very energy-intensive, with fuel costs typically accounting for 30-40% of operating costs. The use of solid waste derived fuels can significantly reduce the operating costs of cement kilns, while at the same time offer an alternative waste disposal route under sustainable waste management strategies
