Coal ash, also referred to as coal combustion residuals or CCRs, is produced primarily from the burning of coal in coalfired power plants. Coal ash includes a number of byproducts produced from burning coal, including: Fly Ash, a very fine, powdery material composed mostly of silica made from the burning of finely ground coal in a boiler.
In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter, produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilie materials such as clay during the cement kiln stage.

the range of 690 750 kcal/ kg of clinker production. Normally all such kilns are equipped with multistage Preheater and precalciner. For each of the processes mean specific energy consumption figures were taken into account for evaluation of grade wise coal requirement per ton of clinker production in cement plant.
Because the clinker is brought to its peak temperature mainly by radiant heat transfer, and a bright (i.e. high emissivity) and hot flame is essential for this, high carbon fuels such as coal which produces a luminous flame are preferred for kiln firing. In favorable circumstances, highrank bituminous coal can produce a flame at 2050 °C.
