It is Important to Keep the Flame Temperature of Rotary Kiln

As everyone knows, when the large mechanical equipment has been operated for a long time, there will be a lot of heat loss. The relationship between temperature and the quality of the final products is close. When the fire is strong, the skin of rotary cement kiln will be naturally formed, it can better maintain the firing cycle of the refractory brick. Then, Hongxing Machinery will explain the effective ways for the control of flame temperature during the operation process of rotary kiln.

1. Strictly control the swirl air around the rotary kiln. We can transport the swirl air from the pulverized coal conveying tube to the outer tube. The small amount of swirl air will be formed inside the pulverized coal pipe, and it will form a certain peak difference. In this way, the outer tube of pulverized coal pipe will form a vortex, and it will maintain a uniform strength. Of course, the volatility of rotary kiln fuel and formation of the peak temperature will remain constant.

2. Increase the wind speed of rotary kiln and arrange a smoke collecting cover. If the wind is too large, the flame will extend naturally. But the effects of smoke cover mainly accelerate the diffusion speed of kiln flame to keep the uniformity of the flame intensity.

3. The swirl angle device of the rotary kiln also should be adjusted appropriately, which can change the shape of the flame.

4. The design of rotary kiln burner is very important. The burner has two forms, which are aimed at converging into a gas reflux, and producing a large amount of air outside of the flame. The return way is on the basis of the central part of the air flow in parallel manner. Air circumfluence will promote volatilization of coal powder, and it can reduce the temperature of peak steep at the same time.
