Computer Simulation of Heat Transfer in a Rotary Lime Kiln
The kiln length predicted by the present model is 5.74 m as compared to 5.5 m of the pilot kiln used in the experimental study of Watkinson and Brimacombe (1982, Watkinson, A.P. and Brimacombe, J. K., "Limestone Calcination in a Rotary Kiln," Metallurgical Transactions B, Vol. 13B, pp. 369–378).

combustor of rotary kiln in south africa
The high temperature typically encountered in the secondary combustor/boiler chamber of a rotary kiln (1200–1400 °C) likely destroyed any PCDD/F on the ash. The ash was sampled upstream of the post-combustion zone, preventing re-formation of these compounds at lower temperatures (T . 600 °C). However, our work …

Coal desulfurization in a rotary kiln combustor. Final report, …
The results suggest that the rotary kiln boiler, as designed, is ill-suited with respect to low-grade, hard to burn solid fuels, such as anthracite culm. Indeed, data from combustion of bituminous coal in the PEDCO unit suggest that with respect to coal in general, the rotary kiln boiler appears inferior to the circulating fluid bed boiler.

Modeling of Pulverized Coal Combustion in Cement Rotary Kiln
In this paper, based on analysis of the chemical and physical processes of clinker formation, a heat flux function was introduced to take account of the thermal effect of clinker formation. Combining the models of gas−solid flow, heat and mass transfer, and pulverized coal combustion, a set of mathematical models for a full-scale cement rotary kiln were …
