The presence of yellow or orange flames in a low-pressure boiler is a strong indicator of poor combustion. In an ideally functioning boiler, the flames should be blue, which indicates that combustion is occurring efficiently with a proper air-to-fuel ratio. When flames are yellow or orange, it suggests incomplete combustion, which can be caused by insufficient air supply or excess fuel. This incomplete combustion can lead to the production of carbon monoxide, soot buildup, and overall inefficiency in the boiler system.

Recognizing the color of the flame is an important skill for those operating boilers, as it not only signals a potential problem with combustion but also indicates that adjustments may be necessary to ensure safe and effective operation. Monitoring flame color allows operators to take timely action to prevent more serious issues, such as equipment damage or safety hazards.
