Boiler Efficiency Improvement & Heat Loss Explained in …

The combustion efficiency of a boiler signifies the burner's capacity to burn fuel. It has two parameters that determine the burner efficiency: unburnt fuel supplies in the exhaust and excess oxygen levels in the exhaust. As the value of excess air is increased, the amount of unburnt fuel in the exhaust decreases.
