Experimental and Numerical Study of Gas Injection Effect on the Methane–Air Combustion inside a Coaxial Burner

This paper is devoted to the analysis of effect gas injection on efficiency gaseous fuel burning. A coaxial burner with a perforated inner wall presented in which methane–air acceleration observed. With use numerical analysis, it demonstrated that flame related flow separation from that, turn, leads reduction heat losses as well vortex formation and momentum losses. On basis obtained results, new technology efficient burning fuels can be proposed and/or liquid injection.
