Formula for Calculating Fuel Consumption of Steam Boiler

When purchasing industrial steam boilers, customers pay more attention to the cost of steam boiler, especially the fuel consumption in operation costs. The following are the fuel calculation formulas for saturated steam boiler and superheated steam boiler.

For saturated steam boilers

Bj = B (1-q4/100)
Bj - Calculate fuel consumption, kg/h
B-Fuel consumption, kg/h
q4-Boiler machinery incomplete combustion loss,%

B = 100Q/(Qdw*η)
B-Fuel consumption, kg/h
Q-Boiler effective utilization of heat, kj/h
Qdw-Low calorific value of fuel, kj/kg
η - Boiler thermal efficiency,%

Q=D(Ibh-Igs-rω/100)+Dpw(Ibs-Igs)
Q-Boiler effective utilization of heat, kj/h
D-Boiler rated evaporation, kg/h
Ibh-Saturated steam enthalpy of boiler at rated pressure, kj/kg
Igs-Enthalpy of boiler feed water, kj/kg
r-Latent heat of vaporization ofsaturated steam, kj/kg
ω-Steam humidity,%
Dpw - Boiler discharge, kg/h
Ibs - Saturated enthalpy of water of boilers at rated pressure, kj/kg

For superheated steam boilers

Q = D (Igr-Igs) +Dpw (Ibs-Igs)
Igr-Enthalpy of superheated steam, kj/kg
