CFD MODELING OF A CEMENT KILN WITH MULTI

temperature and gas components in a cement rotary kiln were obtained by numerical simulation of a 3000 td rotary kiln with a four-channel burner. A zone wise heat flux model was presented which accounted for the thermal enthalpy of the clinker formation process and gave more insight to fluid flow temperature etc. within the cement rotary kiln.

rotary kiln is. Let us explain these points briefly 1. Age and condition of the rotary kiln shell Old kilns shells have been exposed to creep for a long time and are more prone to develop fatigue cracks than newer shells. 2. Distance between tires The longer the rotary kiln shell span the less it will resist high temperatures without sagging.
