rotary kiln. This is determined by (i) the maximum flow rate of the proposed burden through a kiln, and (ii) the residence time at temperatures that would allow sufficient reduction to take place. A calculation method was developed that allows for the prediction of the bed profile and residence time in a rotary kiln.

heat transfer calculations useful for estimating the effects of kiln design and operation on burden temperature. This pa-per presents a mathematical model of heat transfer in direct-ly-fired rotary kilns. The model uses one-dimensional zon-ing along the kiln axis with a mean beam length radiation model.

Abstract This paper deals with the mathematical modelling of a rotary kiln, which is used for the recycling of aluminium waste. This model is mainly based on the coupling between • “a bed model” describing the processes occurring within the bed of aluminium waste flowing inside the kiln, • “a kiln model” describing heat transfer within the kiln itself, • “a gas model
