Product FEATURE

Vertical preheater is one of the main equipment in active lime production. And its main function is to send limestone from the upper part to the body of preheater. Making use of high-temperature exhaust gas (950℃--1100℃) discharged from the calcinations kiln to make heat exchange and the preheat the materials evenly into 900℃ in the preheater.
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. Refractory bricks liner with good design and sealing, 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. If vertical preheater used in calcination system, the capacity will be increased 30%, thermal efficiency will be increased 40%.
