Description

In FIG. 1 shows a longitudinal section through the nozzle head along line ABGD in FIG. 2; FIG. 2 is an external view of the liner and FIG. 3 is a longitudinal section of a modified nozzle head.

In the case 2 of the nozzles, the tube 1 is centrally mounted with an insert 8 (Fig. 1) mounted on its end, having two grooves b around the circumference, connected to the mixing chamber 7 tangentially to it by the spaced channels 3. These last, with the help of the channels 5 drilled in them communicate with the tube. The oil coming through pipe 1 to channels 5 is carried by steam going through recesses 6 and channels 3 to mixing chamber 7, in which displaced steam and oil acquire rotational motion due to tangentially located channels and are thrown into the furnace through the nozzle tip outlet. In the embodiment of FIG. 3, the steam enters the displacement chamber 7 through a screw thread made on the cylindrical surface of the insert 8, and carries the oil out through the channels connecting the screw thread to the oil supply pipe 1.

The subject of the patent.

A steam-mechaic nozzle, characterized in that the channels L are located at the right angle to the steam channels 3 located on the end surface of the liner 8 tangentially to the chamber 7 (Fig. 1 and 2), and which form a screw thread on its cylindrical surface {FIG. 3).
