Product Description

Vertical Preheater In Cement Production Line & Lime Calcination Plant

 

 

Vertical Preheater Introduction:

Vertical Preheater is one host device of the active lime production, and its main function is to sent limestone from the upper part to the body of preheater, while using high-temperature exhaust gas (950--1100 degrees Celsius) discharged from the calcinations kiln to make heat exchange, and the preheat the materials evenly into 900 degrees Celsius in the preheater. After preheating, there is 30% CaCO3 will decompose and then pushed into rotary kiln for burning by the hydraulic push rod. So such a calcinations process not only shorten the time of limestone burning in the kiln, but also get a high degree of the active lime.

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.
