What can adjusting the fuel oil header pressure during a white smoke condition lead to?

Adjusting the fuel oil header pressure during a white smoke condition can lead to a boiler explosion due to the fact that proper combustion relies on the right balance of fuel and air. White smoke usually indicates incomplete combustion, often caused by excess fuel entering the combustion chamber without enough air to burn it completely.

When the fuel oil header pressure is adjusted, it can exacerbate the issue by increasing the amount of unburned fuel if the combustion process is not adequately controlled. If this unburned fuel accumulates and the conditions in the boiler fluctuate, it can potentially lead to an explosive situation if there's a sudden ignition of the fuel-air mixture.

Maintaining the correct fuel oil header pressure is crucial for ensuring that the combustion process remains stable and safe. Therefore, inappropriate adjustments during a condition like this can significantly increase the risk of hazardous outcomes, including a boiler explosion.
