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).
