Description

In the proposed mechanical nozzle, in order to communicate the rotational and translational motions to the liquid fuel, the rotation is attached to the outer tube in which the fixed

BANDAGE.

The mechanical nozzle shown in the vertical section of the drawing consists of a rotating tube L and a fixed screw E with a pointed end placed inside it. The screw E has a square cut and is kept from rotating by a square shank d. The gap between the inner surface of the tube and the outer surface of the screw thread is made according to the pressure that is required to be created in the constricted portion of tube A. When the tube A rotates from the steam turbine B, screw E transfers oil or other liquid fuel from the box D to the spray hole / , on the narrowed end of the tube. Liquid fuel enters the box through the pipe and through valve C

At the narrowed end of tube A, a fan G is mounted on it, forcing air into the housing H and calculated so that the air passing to the nozzle / C of which passes into the diffuser L acquires, in the narrow part of the nozzle, the speed necessary for its initial carburization . The narrow section of the nozzle K is in the plane of the spray hole.

Sprayed fuel approaches the end edge of the diffuser L from the inside, and air enters the channel h from the outside, due to natural thrust. At the edge of the diffuser L, vortex formation and secondary mixing of the fuel with a new amount of air occurs. The air required for the complete combustion of the fuel enters through the openings of the air register and approaches the torch of burning fuel outside the truncated cone O, lined with refractory bricks. The air register consists of two parts: a fixed truncated cone M attached to the front of the firebox and a movable

 N, entering tightly into the still. By turning the cone A, the holes of the register can be enlarged or reduced.

The fire chamber is closed by a door P, lined inside with refractory bricks and hanging on hinges, the paws of which are cast together with the cone W On the same hinges x the case fi also has a fan G, to which the case of the steam turbine 5 with its bearings and generally everything fixed parts of the device.

During the inactivity of the nozzle, it is possible to turn the entire device on the hinges by 90 ° and close the opening in the door. I use a special plug.

The subject of the patent.

1. A mechanical nozzle, characterized by the use of a rotating tube A, within which a fixed screw E. is placed.

2. The form of execution of the nozzle indicated in paragraph 1, characterized in that a steam turbine B serves to bring the tube A to rotate.

3. The form of execution of the nozzle, indicated in clause 1, characterized with the use of the fan G, mounted on the rotating tube A and used to supply air to the diffuser KL.
