How to calculate boiler efficiency by Direct Method
Nov 24, 2016 · Boiler Efficiency by Direct Method This is also known as ‘inputoutput method’ due to the fact that it needs only the useful output (steam) and the heat input (i.e. fuel) for evaluating the efficiency. This efficiency can be evaluated using the formula:

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,
