How to calculate the boiler efficiency by using Direct method.
Assume
Q = Quantity of steam generated (kg/hr)
H = Enthalpy of steam (Kcal/kg)
h = Enthalpy of water (kcal/kg)
GCV = Gross calorific value of the fuel.
1
E = [q(H - h)/Q * GCV] * 100
2
E = [Q(H - h)/q * GCV] * 100
3
E = [Q * GCV] * 100
4
E = [Q(h - H)/q * GCV] * 100
