SWIRLER Russian patent published in 2011 - IPC F23D11/04 

FIELD: machine building.

SUBSTANCE: swirler consists of case with swirling chamber and of nozzle. The case is made as a supply connecting pipe with the central orifice and a coaxial cylinder sleeve with external thread rigidly jointed to the connecting pipe. The nozzle is connected to the case in its lower portion and coaxially to it by means of a sleeve with internal thread. The nozzle is made as a centrifugal swirler of liquid flow and corresponds to a cylinder insertion with at least three tangential inputs in form of cylinder orifices. Also, the sleeve is a part of the nozzle and is installed coaxially and axially relative to the centrifugal swirler with a cylinder throttle orifice on its end surface. The centrifugal swirler is positioned in a cylinder chamber of the case forming a circular cylinder chamber for supply of liquid to tangential inputs of the centrifugal swirler; the latter is connected to a diffuser outlet chamber.

EFFECT: raised efficiency of spraying by increased spray.
