Experimental Study on Hyper-enthalpy Combustion of Low Concentration Coal Mine Gas in Porous Media
Aiming at the problem that low-concentration gas cannot be directly combusted,a low-concentration gas oxidation system was designed using the principle of porous media hyper-enthalpy combustion,and the combustion characteristics and pollutant emission levels of different concentrations of gas were explored.The results showed that:porous media hyper-enthalpy combustion The technology broadens the combustion limit of gas under normal temperature and pressure,and can realize safe and stable combustion of gas with a concentration higher than 3.5％.Porous media can strengthen the mixing and dispersion effect of gas,enhance combustion and make the temperature in the combustion area quickly become uniform,avoid local high temperature,and reduce the generation of CO and NOx.This technology responds to the national"double carbon"strategy and has huge economic and social benefits.
