WHIRL INJECTOR FOR SPRAYING BLACK OIL WITH STEAM Russian patent published in 2006 - IPC F23D11/10 

FIELD: the invention refers to arrangements for fluid combustion and may be used in pipe furnaces in chemical, petrochemical and petroleum industries and in heat engineering arrangements of different purposes in other branches of industry.

SUBSTANCE: the whirl injector for spraying black oil with steam has a body provided with channels for feeding fuel and a sprayer, a whirl chamber with an output contraction nozzle and a central opening in the bottom connected with the channel for feeding of the injector, unilateral tangential openings in the wall of the chamber. The technical result is achieved due to the fact that one of the tangential openings at a tangent to the bottom is connected with the channel of feeding fuel and other tangential openings connected with the channel of the feeding of spray are evenly distributed along the circumference and evenly spaced along the whirl chamber. At that the diameter of the whirl chamber in the point of feeding fuel is less than the diameter of whirl chamber in the point of feeding spray and at the point of passing of the part of the chamber with lesser diameter into the part with larger diameter a number of radial openings evenly distributed along the circumference and connected with the channel of feeding spray is made.

EFFECT: allows to improve quality and efficiency of spraying black oil with steam due to preliminary spraying fuel on drops, mixing them with the spray and breaking up of the drops with the interlaminar tensions of the shift in the whirling flow of emulsion.
