Lean gas heating problem
Thread Content
A 65-hole coke oven in our factory is currently heated with lean gas. The temperature of some combustion chambers cannot rise. After inspection, it was found that the distribution ratio of air and gas seems to be wrong. When rising, some combustion points are biased toward the air chute opening, and some are biased toward the gas chute opening. May I ask what this phenomenon means? How to deal with this phenomenon?
The normal situation is not that the flame is exactly in the middle, but slightly biased towards the air chute mouth. If the normal phenomenon is biased toward gas, what is the temperature of the fire channel? If the temperature is low, there is less gas or more air. At the same time, it should be considered based on whether the fire channel is burning and turbid, adjusting the position of the bricks, leakage, and blockage of the chute.
Thanks for the tip. The current situation is: The temperature in the row on the side of the machine is low, and the combustion point is biased toward the gas chute opening. The situation is better at the burner on the machine side. There are 12 to 14 holes inside. This phenomenon is very obvious, resulting in uneven temperature distribution on the machine side, high burner temperature, and low temperature inside. Now the gas volume has been increased. How to reduce the opening of the damper. Is this appropriate to handle?
