Heat Transfer in the Non-reacting Zone of a Cement Rotary Kiln

Feb 01, 1996 This paper presents a steady-state heat transfer model for a rotary kiln used for drying and preheating of wet solids with application to the non-reacting zone of a cement rotary kiln. A detailed parametric study indicates that the influence of the controlling parameters such as percent water content (with respect to dry solids), solids flow

EVERYTHING YOU NEED TO KNOW ABOUT HEAT

Kiln burning can be defined as exercising control over all heat transfers that take place within and in the proximity of the rotary kiln. A kiln operator has little control over the type of heat exchange that takes place.Whether it will be radiation, conduction, or convection is primarily fixed and governed by the design of the equipment.But control over the amount of heat transfer that takes
