### Calculating Boiler Efficiency - Forbes Marsha

In actual practice, two methods are commonly used to find out boiler efficiency, namely direct method and indirect method of efficiency 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…
