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.

Read More2020-12-18 · Boiler efficiency may be indicated by. Combustion Efficiency - indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust; Thermal Efficiency - indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the boiler, exclusive radiation and convection losses; Fuel to Fluid Efficiency - indicates the

Read More2020-12-18 · To calculate the Carbon Dioxide - CO 2 - emission from a fuel, the carbon content of the fuel must be multiplied with the ratio of molecular weight of CO 2 (44) to the molecular weight of Carbon (12) -> 44 / 12 = 3.7. Carbon Dioxide emission from burning a fuel can be calculated as. q CO2 = c f / h f M CO2 /M m [1]. where. q CO2 = specific CO 2 emission [kg CO2 /kWh]

Read MoreWhere energy to steam is the heat transfer required to form steam. Let, h 2 =specific enthalpy of steam formed, [kJ/kg], h 1 =specific enthalpy of feed water, [kJ/kg]. Because the steam is formed at constant pressure, heat transfer required to form 1 kg of steam in the boiler is. Energy to Steam= (h 2-h 1) [kJ] Energy from fuel is computed from
