CENTRIFUGAL-PNEUMATIC JET Russian patent published in 2009 - IPC F23R3/28 F23D11/00 

Abstract RU 2374561 C1

FIELD: machine building.

SUBSTANCE: centrifugal-pneumatic jet is provided for operation in combustion chambers of gas-turbine units and jets. Centrifugal-pneumatic jet contains hollow casing of air channel with section of taper, outfitted by scapular swirler of air at inlet, installed by axis of casing up to its minimal cross section fuel nozzle with centrifugal jet, including fuel-feed canal to inlet into centrifugal jet. Centrifugal jet allows swirl combustion chamber with air swirler at inlet and nozzle at outlet. Blades of air swirler are implemented as hollow and its outlet edges by radius of channel allows reach-through holes. Swirlers of fuel at inlet to swirl combustion chamber are implemented in the form of screw with through helical grooves on its external surface. Swirl combustion chamber through equispaced by circle though inclined to axis holes of spill in screw and main, in which it is installed diverter valve with casing, is connected to hollows of blades of air swirler. Wall of swirl combustion chamber from the side of nozzle is implemented of type of conical or spherical and is outfitted by equispaced by circumference inclined to axis through holes.

EFFECT: reduction of fuming level and emission of harmful substances in fuel combustion materials, high efficiency and steadiness of burning in combustion chamber and excluding of unproductive bypassing of fuel from jet into tank.
