cement kiln alternative fuels

Cement-making is energy-intensive. The spiralling cost of fossil fuels over the past two decades, combined with a move towards improved environmental performance, has led the industry to turn to alternative fuels to part-replace fossil fuels, such as coal and petcoke, to heat cement kilns. There are a number of sustainable and offer considerable benefits to the CEMEX approach, including reduced …

    This alternative cement kiln fuel is created by innovatively processing and blending organic wastes to a strict protocol. The high temperatures of the cement kilns (over 1,450°C) and long duration of the cement kilns completely utilises all the energy value from the organic waste. The use and creation of Cemfuel has many benefits including:

    Nov 18, 2010 · Some of the waste materials used as alternative fuels in cement kiln systems such as polyvinylchloride (PVC), chlorinated hydrocarbons, sewage sludge, and meat and bone meal can increase the amount of chlorine (Cl) introduced into the system (Saint-Jean et al, 2005). Fuels containing high (> 0.7 percent Cl) can adversely affect the performance of some types of electrostatic …

    1 Suitability of cement kilns for the combustion of secondary fuels. Compared to other high energy-intensive production processes of cement clinker burning process allows a relatively high potential to use secondary fuels [1].This is due to the robustness of the clinker burning process and in its principal layout as a countercurrent process

    Furthermore, a model is developed to describe the combustion in the cement kiln.Alternative fuels for the cement industry can be both solid and liquid. Some of the most widely used are shredded tires, meat and bone meal, and solid recovered fuel (SRF). SRF is a fuel derived from the mechanical treatment of non-hazardous municipal or industrial waste

    tyres as an alternative fuel- cemfuels

    The use of tyres as a fuel in cement production influences kiln operation and clinker composition. Sulphur - Due to the high sulphur content the circulation of volatile salts increases - depending on the sulphur content of the substituted coal - and therefore the coating tendencies in the area of the kiln inlet, riser and lower cyclones also increase

    Using wastes as alternative fuels in cement kilns is the EPA’s highest rated and approved technology for energy bearing wastes. Cement kilns have the highest waste destruction rates at above 99.999%. Wastes are destroyed most effectively in cement kilns because they are exposed to temperatures above 2600°F and with long residence times
