Disclosed is an indigenous LPG gas burner with improved combustion and higher thermal efficiency and reduced emissions. Further the burner is designed to have a co-axially placed second venturi tube inside of the main venturi tube which is pulled up during slow cooking and thus less cross sectional area of the inner venturi tube creates comparatively higher rate of pressure drop inside of the tube for which sufficient air is available for blue flame combustion.
The burner design enhances high velocity pre-flame mixture from the mixing tube into the burner barrel tangentially at about 30 degree inclination with the barrel horizontal axis so that perfect homogeneous mixing can be achieved due to the swirling motion of the pre-flame mixture inside of the barrel.
