Abstract
ABSTRACT
Rotary Kilns are one of the most widely used pieces of processing equipment. They are used for drying or calcinng a variety of products including sand, aggregates, limestone and food products. Heat transfer in rotary kilns encompasses all the modes of transport mechanisms, that is conduction, convection and radiation. In rotary kiln operations the chemical reactions in the bed required high temperatures. The energy to raise the temperature and drive endothermic reactions is from the combustion of a range fuels such as heavy oil, natural gas, coal and more alternative fuels. Heat transfer from the gas to the bed is complex and occurs from the gas to the bed surface and kiln wall to bed surface via conduction, convection and radiation. The study concerned to perform a mathematical modeling to simulate of the heat transport in the cement rotary kiln to predict the temperatures at internal and external wall surfaces of the rotary kiln to preventing many industrial problems through the operation process such as (loss of coating, red spots formation, ….) also to predict the optimum range conditions for safe operation. The results obtained show that, the predicted data using a mathematical model satisfied with industrial data for burning zone. The study showed a derived mathematical model can be used with a good reliability to description of heat transfer in burning zone of rotary cement kilns.
