VORTEX BURNER Russian patent published in 2007 - IPC F23D14/24 

FIELD: combustion.

SUBSTANCE: vortex burner comprises central pipe for supplying oxidizer and outer pipe for supplying fuel. The central oxidizer supply pipe and fuel supply pipe are axially aligned. The oxidizer supply pipe is provided with the deflecting housing that is coaxial to the pipe and is provided with the blades of static swirler and central coaxial cylindrical passage. The outlets of the deflecting housing, the pipe for oxidizer supply, and the pipe for fuel supply are U-shaped to turn around the burner. The surface of the deflecting housing traces the inner wall of the pipe for supplying oxidizer, and the blades of the swirler pass from the surface of the body having no aerodynamic form to the surface of the deflecting housing. The inner and outer blades of the swirler are mounted inside the swirler with an inclination of from 15 to 75 degrees, preferably 20-45 degrees. The outlet cone angle of the central pipe for supplying oxidizer and outer pipe for fuel supply ranges from 15 to 60 degrees, preferably from 15 to 40 degrees.

EFFECT: enhanced reliability.
