Daswell vertical preheater is an important heat recovery equipment of modern lime calcination plant.It is usually attached to the end of rotary lime kiln. Daswell vertical preheater preheats/pre-calcines limestone feed by using the exhaust hot gases from the limestone rotary kiln before entering the preheated limestone into the rotary kiln for further calcining.
Mar 09, 2014· The area of the preheater where fuel is burned is called a precalciner. With a precalciner, the particles are nearly completely calcined as they enter the rotary kiln. Preheaters and precalciners save on fuel and increase the rate at which the mix can be moved through the rotary kiln. 21 November 2015 Prof. Dr. H.Z. Harraz Presentation Cement 29
