Air Flow Rate Calculation (Flue Exhaust Gases). 1 volume of gas requires So 12.5 times the gas volume are approx exhausted from the chimney. Example,. 1,000 kW boiler operating at 90% efficiency gives burner firing rate of 1,099 kW.
Mar 05, 2019 · Flue Gas Dilution the calculation is: Flow rate in l/sec = 4.44 x rated input of boiler in kW. The volume flow rate provided by the fan will depend on the static pressure imposed by the size and length of flue …
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

How to Calculate Boiler Steam Flows | Hunker
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. The composition of the dry flue gas leaving the boiler at

Assuming that flue gases contain only these two gases, the losses [kW]can be calculated as: φ L1 = m& CO ⋅ H l,CO + m& H 2 ⋅ H l, H 2 (9) where m& CO is the mass flow of carbon monoxide [kg/s], m& H 2 the mass flow of hydrogen, H l,CO the lower heating value (LHV) of carbon monoxide (10,12 MJ/kg), and H l,H 2 the lower heating value (LHV) of hydrogen (119,5 MJ/kg).
