Refratechnik - Preheaters

The preheater is a component installed upstream of the calciner and the rotary kiln of a clinker/cement plant. By means of the counterflow principle, the injected raw meal is heated in stages by the upward flow of hot gas, whereby the meal is calcined (deacidified) by up to about 95 %. Depending on the raw mealʻs moisture content and plant ...

WASTE HEAT RECOVERY POWER PLANTS IN CEMENT

2015-3-23  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).
