COAL FUEL OIL AND NATURAL GAS FOR CEMENT PRODUCTION
Coal fuel oil and natural gas are the most commonly used energy carrier in cement industries. The energy use for cement production is distributed as follows -. 1.9 for raw grinding (Choate 2003). The choice of fuel use entails the level at which green house gases (GHG) are emitted the cost of cement and the quality of the cement produced.

Cement Clinker Quality Control During Clinker Production
3. Coal Fines. Many cement plants use bituminous coal as the fuel of rotary kiln so the ash content volatile matter calorific value fineness and moisture of coal fines will affect the clinker calcination process in the kiln. Coal fines. Coal fines are usually prepared by air swept coal mill or vertical mill.

COAL ASH PROPERTIES IMPACT ON CLINKER QUALITY
The impact of using high CaO flyash (ie Class C ash) in cement is likely to improve the strength development of the PPC due in part to the pozzolanic reaction but more so since high CaO ashes contain increased quantities of calcium silicates and aluminates (identical to those found in clinker) which give cement made with these ashes a degree of self-cementing properties resulting in

Coal in the cement industry
chlorine or sulphur is not favoured in the cement plant. The selection of coal for cement industry should be judiciously done. The temperature vis-à-vis heat required in the rotary kiln depends on the composition of raw feed. Hence the coal should be selected in such a way that it should be able to generate requisite gross calorific value.
