A recirculating vortex burner wherein liquid fuel is vaporized in suspension by recirculating hot products of combustion and is thoroughly mixed with air in order that substantially carbon-free combustion occurs. The burner employs a combustion chamber into which air is supplied at one end by a plurality of fixed orifices that provide air jets for producing a spiraled swirling flow pattern in the chamber. Such flow pattern establishes a stable vortex with a relatively low pressure region in the chamber central portion and results in substantial recirculation of the products of combustion. The air jets intersect fuel sprayed into the chamber and entrain such fuel together with the recirculating products of combustion so that air, fuel and products of combustion are thoroughly mixed and the fuel is substantially gasified prior to combustion.

A recirculating vortex burner comprising in combination: a substantially cylindrical combustion chamber having an intake port forming a portion of one end and at least one exhaust port at or near an opposite end; a conduit means leading to the intake port of said chamber; a swirl member disposed in the intake port of the combustion chamber to restrict air flow from said conduit means to said chamber, said swirl member having a central opening and a plurality of spaced apart inlet orifices circumferentially disposed around said opening and directed through said swirl member tangentially to said opening and at an incline to the longitudinal axis of said central opening to communicate between said conduit means and said combustion chamber whereby air can be directed through said orifices in said swirl member into said combustion chamber; and a fuel nozzle disposed in the central opening of said swirl member for providing a conical fuel spray that intersects the air flow entering said combustion chamber through said swirl member orifices, said fuel nozzle and said swirl member cooperating together to seal off the intake port of said combustion chamber whereby air from said conduit enters said chamber solely through said orifices.
