Introduction

The vertical preheater is a vertical preheating device that preheat calcined material, it’s developed on the basis of import and absorb advance technology from abroad and combine with dolomite and limestone calcination features, with characteristics such as rational structure, high rate of heat exchange, high level of automatic.

It main used to preheat raw material with poor thermal stability (such as limestone, dolomite and so on). The vertical preheater is used with rotary kiln, make the high temperature air from kiln tail fully utilize, play a role in saving energy and reducing consumption, it’s a energy saving and environment - friendly product.

Features

1. Push head and main parts of body is made of heat resistance steel, so it can work in 1000~1100℃ high temperature, and have long operation life.

2. Effectively recycle heating energy in waste gas from kiln inlet , to insure the material is preheated equally and reach to preheating temperature.

3. Recycle the heat energy in waste air that discharge from kiln tail effective, increase utilization ratio of fuel, at the same time, it's benefit to dedust;

4. The vertical preheater is used in calcination system, the length of rotary kiln will be shorten, to reduce the heat loss on the surface of rotary kiln and floor space;

5. With good combined revenues, the capacity will be increased 30%, thermal efficiency will be increased 40% after use vertical preheater.
