Cement production has advanced greatly in the last few decades. The traditional fuels used in traditional kilns include coal, oil, petroleum coke, and natural gas.

LIFE CYCLE ASSESSMENT OF THE USE OF ALTERNATIVE

2016-6-24  Moreover cement production is responsible for 5% of the global anthropogenic CO 2 emissions and 7% of industrial fuels use [5,6]. Cement consists of a material called clinker which is formed when the raw material limestone is burned at high temperatures in a cement kiln [1]. In this process (called calcination) calcium carbonate decomposes and CO and

Alternative Fuels Cembureau

Cement production is energy-intensive and currently a mix of coal, petcoke, biomass and waste materials is used as a fuel source. Use of alternative fuels like biomass or waste materials has an immediate impact on the industry’s carbon profile, and while the industry already uses large quantities of such materials, this may well be increased in the future.

Cement Sector Trends in Beneficial Use of Alternative

2016-2-20  Table ES-4 summarizes the energy content of conventional and alternative fuels used in cement production. Many alternative fuels used in cement production have lower energy content than coal, the primary conventional fuel used in cement production, or require further processing to increase the energy content to the approximate energy content of

Life cycle assessment of the use of alternative fuels

2018-6-15  Cement contains a material called clinker which is formed when the raw material limestone is burned at high temperatures in a cement kiln (Van Oss and Padovani, 2002). In this process (called calcination) calcium carbonate decomposes and CO and CO2 emissions are produced (Chen et al., 2010a, Chen et al., 2010b).

Life cycle assessment of the production of cement:

2016-11-20  Cement kilns use different energy sources to reach the high temperatures necessary to form the clinker. Many fuels can be used: fossil fuels, as mineral coal, fuel oil, petroleum coke, natural gas and diesel; and alternative fuels, as waste or biomass (Madlool et al., 2011).

Update on solid waste derived fuels for use in cement

2014-3-13  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 waste fuels.
