WASTE HEAT RECOVERY POWER PLANTS IN CEMENT …
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).

The consumption of the energy in the cement plant is mainly due to raw mill, cooler, pre-heater and rotary kiln [14]. The total energy loss of the plant is generally accounted for about 35-39% of the total energy input [15]. This energy loss is due to the loss from the exhaust gas, cooler and the radiation heat transfer from the kiln cell.
