    4 Apr 2017 The device, which comprises a rotary kiln equipped with an external electrical heating To calculate the heat balance, it is necessary to 2.5 kg h-1, a rotational speed of 3 rpm, a 23.5 mm dam and an inclination angle of 2 .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.Because rotary kilns use heat to cause a physical change or chemical reaction within the material, both direct- and indirect-fired kilns can be used to carry out a variety of processes. An explanation of some of the common applications are listed below. All of these processes can be tested in the FEECO Innovation Center.
