Boiler Efficiency Improvement & Heat Loss Explained in

To measure boiler efficiency in this way, we divide the total energy production of a boiler by total energy input provided to the boiler, multiplied by a hundred. Calculation Formula of direct efficiency of boiler-E= [Q (H-h)/q*GCV]*100. Where, Q= Quantity of steam generated (kg/hr) H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg)
