Vertical Preheater / Metallurgy Calcination Equipment Durable For Active Lime Processing Plant

Vertical Preheater / Metallurgy Calcination Equipment Durable For Active Lime Processing Plant

Vertical Preheater 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.

Vertical Preheater Working Principle:
The Working Principle Of preheater: According to the place of Preheater in rotary kiln system, and negative pressure working principle of Preheater. Heat emission is heat convective, the material and air is convection movement. When the raw materials feeding into the preheater, under the negative pressure condition, to prevent cold air into the preheater, the inlet of raw materials must take effective seal. This is to ensure the effective use of heat and material preheating effect. The standard of preheating quality in the preheater, is the feeding room's temperature which is in the bottom of preheater. Kiln temperature is: Detected by thermocouple in the side wall of feeding room, including the flame radiation and air temperature. It reflects the firing temperature when feed into kiln, but also the degree of feedback the final warm-up temperature of the material. To Preheater, Truly reflects the effective temperature of the material is outlet temperature of the Preheater top. Temperature control on this point is more important than the end of the rotary kiln temperature control. Within preheater, materials after preheating and pre-decomposition, pushing out from Preheater to Rotary kiln by hydraulic plunger device.
