In a cement plant, nearly 35% heat is lost, primarily from the preheater and cooler waste gases. This corresponds to around 70 to 75 MW of thermal energy. This energy can be tapped by installing a Waste Heat Recovery Power Plant (WHRPP). Size of WHRPP is influenced by the moisture content present in raw material and fuel (coal).

Thermal Power Plant - Bureau of Energy Efficiency

Coal quality also affects boiler efficiency which has been covered in earlier sections. A coal with higher GCV means less coal flow and vice-versa. More coal flow means more volume of air to be handled by the ID Fan, which ultimately affects the power consumption from the ID Fans. Due to change in coal quality there may rise a need of starting or stopping a mill. This affects the
