Patent
CA 2085504
A gas burner is described having a cylindrical combustion chamber having at least two spaced apart counter-rotation stationary tangential air injectors and at least three sets of radial injection holes in between for admitting air under pressure in the combustion chamber to cause adjacent counter-rotation air turbulence regions in said combustion chamber. The combustion chamber has a closed end and an open end with a gas injector tube extending in the chamber from the closed end and disposed centrally therein. The injector tube has combustion gas injection ports at least upstream and downstream of the at least two air injectors to create a combustion mixture which is initially fuel-lean to generate a flame having a lower temperature and producing less nitrogen oxide than with conventional gas burners of this type. An air chamber is provided about at least a portion of the combustion chamber and communicates with the tangential air injectors.
