LEE MASIn 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).
LEE MASA development of this process is the 'precalciner' kiln. Most new cement plant is of this type. The principle is similar to that of the dry process preheater system but with the major addition of another burner, or precalciner. With the additional heat, about 85%-95% of the meal is decarbonated before it enters the kiln
LEE MASThe precalcining technology is a technical leap of cement calcining process, with a series of excellent properties and characteristics such as high quality, high efficiency, and low consumption. Add a precalciner between the preheater and the rotary kiln, or use the uptake flue at kiln end, and set up a fuel injection device to make the ...

Consequently, procedures for clearing and hot working in pre-heater towers systems and coolers, should be modified to take account of its recommendations.
LEE MASIn the challenging conditions of a cement plant, traditional process control methods are not always suitable. Radiometric process control provides a non-contact and non-intrusive technique to carry out continuous level measurement, detect cyclone blockages in the preheater, measure bulk flow on the conveyor and moisture measurement.
