What are the effects of inappropriate boiler burner position on calcination?
What impact does improper positioning of boiler burners have on calcination? I believe many of our companies are so particular, there is no need to deny it, there must be! What are the hazards if the position of the boiler burner is not suitable? Let me hear from the editor below!
The hazards caused by several abnormal burner positions on kiln calcination are described as follows:
1. The position of the boiler burner is too high, the flame is long, and it burns far, which can easily damage the kiln skin and make it difficult to control the operation. In addition, due to the high height of the coal pipe, the material cannot be burned. Often, when there is a shortage of incoming materials, it cannot be burned. Once there is a large amount of incoming materials, the black shadow is easily washed over the ignition point, causing slow driving. After slow driving, the temperature is not easy to rise, and once it starts burning, it is easy to overheat. Often, the temperature in the front is just right, but it has already overheated in the back, resulting in passive fast kiln air, significant coal reduction, unstable thermal system, passive operation, and affecting production quality.

2. The position of the boiler burner is too low, and it can still burn when there is less material. However, once there is more material, the flame will burn down and directly come into contact with the material, causing the coal powder to be trapped in the material and incomplete combustion. The surface of the material layer will emit blue flames, the ignition point will become turbid, and there will be more yellow core material, which will affect the color. At the same time, when burned close, the flame is short, and it is easy to form local high temperatures, causing clumping in the front and black shadows to follow closely behind. When driving slowly, it looks like it is burning, and as soon as it drives faster, the material rushes over from one side, forming a sandwich material that is raw on the surface but cooked inside, seriously affecting the quality of cement.
3. The boiler burner is located outside, and the flame is generally coarse and unstable. The ignition point moves forward, the black shadow is close, and the operation is difficult to control. It is easy to slow down and burn out the front kiln skin.
4. Too many burners are fed into the boiler, resulting in poor flame expansion and contraction at the beginning, thickening of the material layer without top material, making the kiln appear turbid and difficult to observe, operate and control. When the flame elongates, it is easy to burn out the kiln skin behind.
