Aug 1, 2020 · Flux analysis for NH 3 /CH 4 mixtures indicates that CH 4 + NH 2 = CH 3 + NH 3 contributes substantially to the decomposition of methane early in the oxidation process, while CH 3 + NO 2 (+M) = CH 3 NO 2 (+M) is a significant reservoir of NO 2 at low temperature.

Toward a carbon-free economy, ammonia is proposed as an alternative with high capabilities to replace hydrocarbon fuels. In the present study, the fundamental combustion properties of the ammonia/methane mixture were investigated experimentally and numerically.

Nov 1, 2022 · Detailed and reduced methane/ammonia combustion mechanisms for gas turbines are proposed. Methane/ammonia combustion in an industrial gas turbine combustor is numerically studied. Increasing fuel’s ammonia content will lead to a longer, thinner, higher lifted flame.

Nov 10, 2019 · Ammonia (NH 3) is currently in the spotlight because of its potential in serving as an energy resource devoid of carbon. Combustion of NH 3, however, presents several drawbacks, such as high ignition temperature, low flame speed, and high NO x emissions.

Oct 4, 2024 · Ammonia (NH 3), as an ideal zero-carbon fuel, plays a positive role in mitigating global warming. By cofiring NH 3 with highly reactive small molecule fuels such as hydrogen (H 2), carbon monoxide (CO) and methane (CH 4), the reactivity of NH 3 combustion can be significantly enhanced.

CH4 + NH3 = HCN + H2 is a Double Displacement (Metathesis) reaction where one mole of Methane [CH 4] and one mole of Ammonia [NH 3] react to form one mole of Hydrogen Cyanide [HCN] and three moles of Dihydrogen [H 2]

Apr 21, 2003 · The rate coefficient for NH 2 + CH 4 → NH 3 + CH 3 (R1) has been measured in a shock tube in the temperature range 1591–2084 K using FM spectroscopy to monitor NH 2 radicals.

Jan 1, 2020 · This study aims to investigate the turbulent combustion characteristics in a bluff-body burner for CH4/NH3 mixtures with different ammonia blending ratios (15%, 30%, and 45% by mole fraction ...

Mar 23, 2024 · Extinction limits and structure of the nonpremixed CH4-NH3/air flames are measured and predicted. Results show that flames gradually become orange and the flame thickness increases with NH3 addn., compared with the pure CH4/air flames. Also, flames can sustain less NH3 at high strain rates.

Mar 11, 2021 · In particular, it was shown that the autoignition process starts with the formation of methyl (CH 3) and amine (NH 2) radicals, through dehydrogenation of methane and ammonia, respectively.
