ABSTRACT:
A fuel burner adapted to produce a stable, non-contaminating blue flame throughout a broad operating range. The burner includes a combustion zone into which is directly fed the combustion air. Air-atomized liquid fuel is fed into the combustion zone through a Venturi whose constricted throat communicates by way of a feedback passage to the combustion zone, whereby the ejector effect produced by the atomized fuel passing through the Venturi causes a portion of the hot combustion gas generated in the combustion zone to be drawn into the throat to intermix with the atomized fuel therein, thereby pre-vaporizing the fuel to insure full combustion thereof.
