The losses caused by the sensible heat of flue gases can be calculated as: m& i L 3 = m& fuel hi (11) i m& fuel where m& fuel is the fuel mass flow [kg/s] m& i the mass flow of a flue gas component and hi the specific enthalpy of a flue gas component (e.g. CO2) [kJ/kg]. Heat loss due to wasted heat in ashes Ash can exit the furnace either as bottom ash from bottom of the furnace or as fly ash with flue gases.

The fuel is considered to be Standard Natural Gas (1040 Btu/std. ft3 ) the fuel consumption is 100000 Btu/hr (HHV Basis) and the heat delivered to the home is 80000 Btu/hour. The percent excess air for this combustion system is 10 %. The combustion air is drawn from
