Example #1 - Determination of the Flue Gas Temperature from a Natural Gas Furnace In this specific example the combustion device is an older lower efficiency Natural Gas Home Furnace. The fuel is considered to be Standard Natural Gas (1040 Btu/std. ft3 ), the fuel consumption is 100,000 Btu/hr (HHV Basis), and the heat delivered to the home is

analyses. The calculated flue gas flow is compared with the reference flue gas flow calculated from the elemental composition. It is shown that, for a wide range of coal and biomass compositions, the above formula performs very well. For light fuel oil the formula is: V God = 1.76435 + 0.20060 H (N) (m 3/kg) and for natural gas: V God

Example 5 Methane is burned with air in a PA Hilton boiler to produce hot water oof 55oC. The fuel is fed at a rate of 7 kg/hr at 25 C, the air enters the boiler at a rate of 130 kg/hr at 42.5oC, and the water enters the boiler at a flow rate of 1000 kg/hr at 10oC.
