High Heat Consumption of Limestone Rotary Kiln

The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect-heated type. Often, indirect heated dryers are used when product contamination is a concern. In some cases, a combination of direct-indirect heated rotary dryers are also available to improve the overall efficiency.

To get off from the simplified the lining of the flake corrosion, can be found by the ultrasonic thickness gauge measurement, simplified have different degree of thinning, some will also appear in simplified the medial surface of the reversing non-uniform groove, such as front wheel of limestone rotary kiln is often find simplified inside groove, the simplified corrosion is most serious area is near the transition zone of large limestone rotary kiln simplified, annual corrosion rate is as high as 1 ~ 2 mm. Limestone rotary kiln belongs to building material equipment in the classification class.

But limestone rotary kiln in the equipment of large itself is also a kind of resource consumption, and also in the process of production of produce certain pollution, in order to prevent in the limestone rotary kiln production produce secondary pollution, in the whole manufacturing system, the limestone rotary kiln is equipped with dust removal system, coal equipment is equipped with three air duct or four duct burner.

Now that you have know the reasons of high heat consumption of cement rotary kiln, many manufacturer to study actively to improve the limestone rotary kiln. Reduce the exhaust gas temperature and unit clinker is to reduce the amount of exhaust gas heat loss is the main way.
