So the stoichiometric air-fuel ratio of methane is 17.2. When the composition of a fuel is known, this method can be used to derive the stoichiometric air-fuel ratio. For the most common fuels, this, however, is not necessary because the ratios are known:

air/methane volumetric ratio is reported: that is the temperature needed from an assigned (air/fuel ratio) mixture to completely burn in the assigned duct length. 1000.0 1100.0 1200.0 1300.0 1400.0 1500.0 1600.0 5 7 9 1113 1517 19 Air/Fuel RATIO Temperature [K] 10 mm20 mm 200 mm 500 mm

2 ). The fuel–oxidizer ratio of this mixture based on the mass of fuel and air is. m C 2 H 6 m O 2 = 1 × ( 2 × 12 + 6 × 1 ) 1 × ( 2 × 16 ) = 30 32 = 0.9375 {\displaystyle {\frac {m_ { {\ce {C2H6}}}} {m_ { {\ce {O2}}}}}= {\frac {1\times (2\times 12+6\times 1)} {1\times (2\times 16)}}= {\frac {30} {32}}=0.9375}

CH 4 + 2O 2 → CO 2 + 2H 2 O + Heat (1,013 Btu/ft. 3) Air contains approximately 21% oxygen and 79% nitrogen. In this case, the reaction for complete combustion becomes: CH 4 + 2O 2 + 7.53N 2 → CO 2 + 2H 2 O + 7.53 N 2 + Heat (1,013 Btu/ft. 3) The amount of air required will vary depending on the type of fuel.

as the fuel (methane-hydrogen mixture) varies and as the fuel-air ratio varies. Analysis of the results obtained also provides information, over the whole range of flammable methane-hydrogen-air

This detailed mechanism for methane-air combustion is probably the most famous one. It is comprised of 325 reactions and 53 species. It is originally an optimized mechanism designed to model natural gas combustion, including NO formation and reburn chemistry. Detailed information about this standard mechanism can be found on this dedicated website.

Formula for fuel utilization efficiency: Fuel utilization efficiency (F.U.E) = -[{(air-fuel ratio +1)*(Specific enthalpy of products)} - {(air-fuel ratio)*(Specific enthalpy of air)} - (Specific enthalpy of CH4) ]/(L.H.V of methane) Air-Fuel ratio = [(stoichiometric mass of air/stoichiometric mass of fuel)]/(equivalence ratio)

If more air is supplied some of the air will not be involved in the reaction. The additional air is termed excess air, but the term theoretical air may also be used. 200% theoretical air is 100% excess air. The chemical equation for methane burned with 25% excess air can be expressed as. CH 4 + 1.25 x 2(O 2 + 3.76 N 2) -> CO 2 + 2 H 2 O + 0.5 O 2 + 9.4 N 2. Excess Air and O 2 and CO 2 in Flue Gas. Approximated values for CO 2 and O 2 in the flue gas as result of excess air are estimated in ...

METHANE MIXTURE IN AIR: flue gas composition A number of moles of flue gas N: N =1 mole CO 2 + 2 moles H2O + 7.52 mole N2 = 10.52 moles According to the wet (water is steam/liquid) analysis of flue gas the concentration of the components is as follows: [CO 2] =1mole CO 2/10.52 =9.5% CO 2 vol. [H 2O] =2 moles H2O/10.52 =19% H 2O vol.
