Alternative Fuels For Use In Cement Kilns
Alternative Fuels For Use In Cement Kilns Process . Recycled in cement kilns in 2010 [17].In 2009, 7449 tonnes of scl were recycled in australia, mostly in the cement industry as an alternative fuel [18].Used industrial lubricants generally have high calorific value, and those can be used in cement kilns as alternative fuel with minimal processing cost [19].
The cement kiln
However, new cement kilns are of the 'dry process' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the preheater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the ...
