ig.1

The invention relates to energy and can be used for burning liquid fuels in thin power plants.

A centrifugal nozzle is known, comprising a housing with a nozzle and a twisting chamber with a conical recess in the end wall 1.

A disadvantage of the known nozzle is low efficiency due to high hydraulic resistance.

Closest to the technical entity, the proposed invention is a centrifugal nozzle comprising a fuel supply pipe with a conical axial divider, an intermediate chamber with inclined inlet openings placed around the divider, and a swirl chamber communicated with the intermediate chamber through tangential channels 2.

A disadvantage of the known nozzle is low efficiency due to high hydraulic resistance.

The purpose of the invention is to increase efficiency.

This goal is achieved by the fact that in a centrifugal nozzle containing a fuel supply pipe with a conical axial divider, an intermediate chamber with inclined inlet openings arranged around the dissector and a swirl chamber communicated with the intermediate chamber through tangential channels, the divider on the side surface is provided with guides - plates forming curvilinear channels connected to the corresponding openings of the intermediate chamber.

FIG. 1 shows a centrifugal nozzle, a longitudinal section; in fig. 2 is a section A-A in FIG. one; in fig. 3 - divider; in fig. 4 is a view B in FIG. 3. The centrifugal nozzle contains a fuel supply pipe 1 with a conical axial divider 2, an intermediate chamber 3 with inclined inlets 4 and a swirl chamber 5 communicated by tangential channels 6 with an intermediate

camera 3. Divider 2 is provided with guide plates 7 forming curved channels c. At the outlet of the swirl chamber 3, an axial outlet nozzle 9 is placed.

When the injector is operating, the fuel enters through the fuel feed pipe 1 and purchase. rotational movement in curvilinear channels 8 retreats, the entrance is almost without loss in the openings 4 of the intermediate chamber 3. Next, the fuel through the tangential

The channels 6 enter the swirl chamber 5, from where through the exit nozzle 9 a conical jet is fed into the combustion space.

The use of the pre-jar nozzle will increase the efficiency of fuel-burning devices.
