One section of the converter in this unit is a negative-pressure top-fired furnace; please discuss ways to prevent uneven burning at the top burners
There is uneven burning at the top; you must be using natural gas.
Uneven burning is caused by problems with the burner; factors such as the angle at which the gas holes and air holes in the burner are positioned play a role, and carbon deposition may also occur within these holes. To determine the exact cause, it’s necessary to remove the burner and examine it in detail.
