Boiler Efficiency : Introduction and Methods of Calculation

Boiler Efficiency : Introduction and Methods of Calculation

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. The indirect efficiency of a boiler is calculated by finding out the individual losses taking place in a boiler and then subtracting the sum from 100%.
