On the use of alternative fuels in rotary kiln burners — An
Some modelling studies of the heat transfer in rotary kilns have been published [5], [6]. In the work by Gorog et al. [5] the heat transfer from the flame to the bed in a rotary kiln was modelled. The kiln was divided into a number of segments in which the temperature of the flame and the heat load on the bed were calculated.
