STRUCTURE, NOX EMISSION, AND EXTINCTION CHARACTERISTICS OF SYNGAS METHANE MIXTURE-AIR COUNTERFLOW DIFFUSION FLAMES
Conversion of coal to syngas has been envisioned to be an environmentally friendly way to utilize coal for power generation in the near to intermediate future. It is essential to know the fundamental combustion characteristics of syngas to design various syngas-fired combustion devices. Currently there is lack of such studies. This paper reports a detailed numerical study of the structure, NOx formation, and extinction of counterflow diffusion flames of CH4-, 50％CH4/50％syngas-, and syngas-air to gain insights into how these fundamental combustion characteristics vary as the fuel is switched from pure methane to pure syngas. The numerical calculations were carried out using CHEMKIN based codes and the combustion chemistry was modelled using GRI-Mech3.0.
