Convective heat transfer in a rotary kiln Tscheng 1979
An experimental study of convective heat transfer from hot air to the solid charge and walls in a non‐fired rotary kiln is reported. Ottawa sand was heated by passing it counter‐current to a flow of preheated air in a 2.5 m 0.19 m I.D. rotary kiln. Axial temperature profiles of gas, wall and solids were measured.
The Division of Air Quality DAQ received a copy of
Mar 04, 2014 30 percent of the heat input to the kiln system by recirculating some of the exhaust air back into the intake air of the kiln. The clinker cooler removes enough heat from the product so that it can be handled with conventional conveying equipment. The more common types of clinker coolers are (1) reciprocating grate, (2) planetary, and (3) rotary.
