Calculating Boiler Efficiency  Forbes Marshall
Direct efficiency. This method calculates boiler efficiency by using the basic efficiency formulaη=(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 efficiencyE= [Q (Hh)/q*GCV]*100. Where,
