Nowadays, large scale production has been carried out in eight high-quality water sources.  Our Product Type

• Calculating Boiler Efficiency - Forbes Marshall

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-E= [Q (H-h)/q*GCV]*100. Where,
