Vcf = (mf x LHV x ηsb) / hrf. Where: V cf = combustion furnace volume (m 3) m f = fuel consumption (kg/s) LHV = Low Heating Value (kJ/kg) η sb = steam boiler efficiency. h rf = heat release rate (kg/m 3 .s) From the above formula can be seen that the volume of combustion furnace can be known if the Lower Heating Value (LHV) is known.
