Boiler Efficiency: Introduction and Methods of Calculation

Direct efficiency. This method calculates boiler efficiency by using the basic efficiency formula-. η= (Energy output)/ (Energy input) X 100. In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. Calculation of direct efficiency-.

Boiler Types: Standard vs. High Efficiency - YouTube

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.
