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).

Preheat Towers

Preheat Towers. Kiln preheater towers provide heat transfer from hot gases to kiln feed material. The counterflow of gases and material takes place in cyclones, referred to as stages, in the preheat tower. As material flows from the top to bottom of the tower, it is exposed to increasingly higher temperatures as it is prepared to enter the kiln.
