CENTRIFUGAL ATOMISER WITH OPPOSITE SWIRL FLOWS OF VZP TYPE Russian patent published in 2011 - IPC F23D11/04 B05B1/34 

FIELD: power industry.

SUBSTANCE: centrifugal atomiser with opposite swirl flows of vzp type includes housing with vortex chamber and nozzle; housing is made in the form of connection pipe with liquid supply hole from main line and cylindrical coaxial sleeve with outer thread, which is rigidly connected to the above connection pipe, and nozzle made in the form of centrifugal swirler of the second stage in the form of cylindrical cavity at least with three tangential inputs in the form of cylindrical holes is connected coaxially to housing in its lower part by means of sleeve with inner thread; at that, sleeve is a part of nozzle and installed coaxially and in-line in relation to centrifugal swirler of the second stage, which is equipped in upper part with cylindrical part continued to conical part forming an annular conical gap with housing; and cylindrical vortex chamber being the first stage of liquid swirler and made in the form of stock coaxially arranged in it with screw plate fixed on it is installed above centrifugal swirler of the second stage. At that, stock is fixed on three bars connected to conical chamber attaching swirlers of the first and the second stages; at that, centrifugal swirler is installed in housing so that annular cylindrical chamber is formed for liquid supply to tangential inputs of centrifugal swirler the cylindrical cavity of which is connected to output conical chamber of nozzle.

EFFECT: higher atomising efficiency by increasing atomising flame and fine atomised liquid.
