Heat Balance Of Rotary Kiln

Dec 01, 2005 Rotary kilns are used ubiquitously in the chemical and metallurgical industries. The mechanism of heat transfer in a rotary kiln is discussed in this paper, in which the effect of rotation is considered in determining heat transfer coefficients. In particular, an extended penetration theory is successfully developed to describe the heat transfer coefficient of the covered wall to the bulk.

These two zones serve to increase the temperature of the pellets prior to the kiln, and here the main part of the oxidation to hematite takes place [9]. Oxidation of the pellets releases a large amount of heat – this is the main heat source in the process[5]. The heated pellet bed then enters the rotary kiln, shown schematically in Figure 2.2.

Lime kilns can be categorized into three groups rotary kilns, vertical kilns, and miscellaneous. About 90 percent of commercial lime capacity in the U.S. is calcined in rotary kilns. Most of the remaining capacity is processed with vertical kilns (vertical kilns are common in captive supply facilities), and small quantities are processed.
