What can result from poor control of air in a boiler system?

Poor control of air in a boiler system can lead to flame impingement, which occurs when the flame touches the surfaces of the boiler or other components. This situation can arise when there is insufficient air for combustion or when the air-fuel mixture is not properly balanced. An improper air-fuel mixture can create areas of excess heat and lead to localized hot spots. When flames make contact with the boiler surfaces, it can cause damage through overheating, ultimately resulting in reduced efficiency and potential safety hazards.

Maintaining optimal air control helps ensure complete combustion and even heat distribution. It also prevents issues like flame distortion that can cause it to behave erratically. Proper air management is essential for ensuring the longevity and safe operation of the boiler system, along with maintaining the desired levels of steam production and fuel efficiency.
