    Calculating Boiler Efficiency - Forbes Marshall

    The combustion efficiency of a boiler is the indication of burner’s 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.

    Boiler Efficiency - an overview | ScienceDirect Topics

    Boiler combustion efficiency is the suggestion of burner capability to burn fuel. The burning efficiency depends on two different parameters such as excess O 2 levels in the exhaust and unburnt fuel quantity in the exhaust. The unburnt fuel quantity in the exhaust decreases with an increase in the excess air amount.

    How to Run a Coal Fired Boiler at the Best Efficiency

    Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.
