Temperature Control of Rotary Kilns

As a professional high-temperature calcination equipment, rotary kilns are essential building materials equipment for cement and other production lines, temperature control for the rotary kiln calcined clinker is very important. ZK Corp machine analyze this in order to ensure the safety of rotary kiln calcination process, stability and efficiency, which temperature need to be controlled?

1. The stability of a cylinder outlet gas temperature control
The gas temperature produced by the primary cylinder reflects the effect of the heat exchange between the material and the gas in the preheater, the incoming situation, the temperature of the whole system, and the presence of air leakage.
Temperature is too high, it will affect the exhaust fan, dust collector safe operation, so that increased heat consumption; temperature is too low, the raw material of the preheating effect is not good.
General control in the range of 320 to 360 degrees, when the feed is normal, the other points of the system temperature is normal, the system ventilation is normal, the parameters will change within the normal range.

2. Stable C5 inlet gas temperature
It can reflect the rotary kiln, decomposition furnace fuel combustion is complete and the size of the system ventilation. When the temperature is too high will cause the furnace after the system crust, plug the phenomenon. The temperature should be lower than the outlet gas temperature of the decomposition furnace. In the normal production, usually do not change the system ventilation, this time by improving the combustion conditions so that the parameters in the normal range.

3. Stable decomposition furnace outlet temperature
It can be reflected in the decomposition furnace fuel combustion and material decomposition. When the temperature is high, it may cause the furnace system material overheat crust blockage, and even burn the decomposition furnace. General control is the 850-890 degrees, can be adjusted by the incoming situation, fuel fineness and moisture, rotary kiln fan pull the size of the wind so that the normal range of changes.

4. Stable rotary kiln flame temperature
It can reflect the rotary kiln fuel combustion conditions. High flame temperature will lead to over-burning material or knot large, and even burned rotary kiln skin and lining material; flame temperature will lead to raw materials, burning, so that free calcium content increased. The general control range is 1600-1800 degrees, by adjusting the rotary kiln kiln feed coal, fuel quality, primary air volume, internal and external air ratio, the location and angle of the coal pipe so that the parameters in the normal range.

Well control the above aspects of the temperature, will be able to guarantee a large degree of rotary kilns calcination process of security, stability and efficiency.
