CENTRIFUGAL NOZZLE WITH PROJECTING PARTS Russian patent published in 2015 - IPC F23R3/28 F23D14/02 

FIELD: machine building.

SUBSTANCE: centrifugal nozzle contains a ring casing with limiting walls, having input area and output area in direction of the main flow, at least two blades located in the ring-shaped casing. Each blade has streamlined profile of the cross-section that passes at right angle to the longitudinal direction or with slope towards the main flow direction prevailing in the centrifugal nozzle. The lead edge area of each blade has profile that is oriented parallel with the main flow direction prevailing at the lead edge. The blade profiles are turned relatively to the main flow direction prevailing on the lead edge to provided the flow vortex. In relation to the central plane of the blades the rear edges have at least two projecting parts that alternatively continue from the central plane in opposite transverse direction. Besides, invention relates to the work method of such torch.

EFFECT: invention ensures high effective centrifugal torch with low pressure drop.
