Boiler Efficiency: Introduction and Methods of Calculation

Combustion Efficiency. The combustion efficiency of a boiler is the indication of burners ability to burn fuel. The two parameters which determine the burner efficiency are unburnt fuel quantities in exhaust and excess oxygen levels in the exhaust. As the amount of excess air is increased, the quantity of unburnt fuel in the exhaust decreases.
