The first part of the article in issue 5/2012 dealt with the basics and case study I. It was shown, how MI-CFD modelling can be used to understand the thermo-fluid dynamics of a calciner. In Part II a second case study and suggestions for the utilization of AFR are presented.
Case study II
The second case study is selected from a natural gas fired plant operating at 40 % heat input in the kiln burner and 60 % in the calciner. The client wanted to replace natural gas by waste derived fuels, i.e., Solid Recovered Fuel (SRF) and biosolids in both calciner and kiln burners. A brief summary of the...
