Abstract:
A liquid fuel combustion apparatus, comprising:a hollow cylindrical combustion chamber member having a first end and a cylindrical wall;an air swirler attached to said combustion chamber member first end and coaxial with said combustion chamber member, for introducing swirling air in a predetermined direction into said combustion chamber member, said air swirler including a hollow annular swirler body with a plurality of swirler vanes therein, each vane being angled with respect to the axis of said annular swirler body;a venturi located to project into said combustion chamber at said first end thereof, adjacent to said air swirler, wherein said venturi includes an opening in which a fuel injection nozzle is located including an elongated, hollow cylindrical nozzle body member having a first end with an inlet opening for flow of liquid fuel into said nozzle body member, and a second end with a single outlet opening positioned to inject the liquid fuel as a jet through said nozzle body member outlet opening into said combustion chamber at an angle of from about 50.degree. to about 60.degree. with respect to a tangential line of the combustion chamber member cylindrical wall in a direction opposite to the predetermined direction of the swirling air, to cause the liquid fuel and the air to mix abruptly and uniformly in a well stirred mixing mode.
