kiln functioning of cement plant

Cement plants use large amounts of energy to produce acceptable clinker. Improved kiln control can lead to substantial energy savings while maintaining high production of quality clinker. Efficient operation of a modern cement plant is dependent on many factors relating to personnel safety, equipment protection, quality control, and energy usage.

Well-established technology, on the one hand, allows the rotary kiln of any cement plant to be fired with low-volatile fuels such as petcoke, low-volatile bituminous coal, and anthracite, without problem (Nielsen et al., 1986). On the other hand, high volatile-low calorific value alternative fuels have limited use in the kiln primary firing system due to their relatively low combustion temperatures.
