Thermal Modeling of Rotary Kiln Processes

It is evident from these relationships why it is preferable to feed a kiln with larger size particles as in the limestone calcination process so as to take advantage of the radiation effect enabled by the interparticle spacing. Through Equation (8.26), the effect of mixing on effective thermal conductance is achieved through two thermal diffusivities. For kiln control purposes, we can recast Equation (8.25) in the form 

In Chapter 6, we considered the combustion of fuel and discussed some results of combustion modeling using CFD. In Chapter 7 we discussed heat transfer in the freeboard and the type of radiation models that go into modeling combustion and establishing freeboard temperature profiles. Having now established the physical models for
