WHIRL BURNER Russian patent published in 2006 - IPC F23D14/24 

FIELD: the invention refers to arrangements in which components of fuel are given rotational motion.

SUBSTANCE: the burner is designed for combustion chambers of stationary gas turbine engines and provides reduction in forming nitric oxide Nox and their rejections into the atmosphere. The whirl burner has a pipeline of feeding of gaseous fuel with a cylindrical mixer of fuel and air coaxially located on it behind its output with an air wane swirler on the input into the mixer and a diffuser at the output. The pipeline of feeding of gaseous fuel has in series connected a fuel collector, a swirler and an output section in the shape of a cylindrical bushing closed from one butt-end and connected from the side of the other butt-end trough the output bushing of the smaller diameter with the mixer of fuel and air, the cylindrical bushing is additionally connected through the water swirler and the water collector with the pipeline of feeding water. At that the fuel and water collectors are located on the cylindrical mixer of fuel and air in the area of the air wane swirler, the fuel and water swirlers are fulfilled in the shape of channels in the blades of the air swirler directed crosswise the longitudinal axle of the burner at a tangent to the inner diameter of the cylindrical bushing.

EFFECT: provides reduction in formation of nitric oxides Nox and their rejections in the atmosphere.
