Description

In the proposed friction steam turbine with provided plates, the disks mounted on the axis of the turbine are reinforced with concentrically arranged annular plates, and the nozzles supplying steam are mounted so that they direct the strings to the inner and outer circles of the plates; exhaust steam through the holes in the disks and the cavity between them enters the discharge pipe.

In FIG. 1 schematically depicts a vertical section of a friction steam turbine; FIG. 2 is the same in another plane of it; FIG. 3 is a perspective view of a part of a disk with plates; FIG. 4-location of nozzles near the plates.,

On the shaft that passes through the casing, there are disks L (Fig. 1), on the outer sides of which there are reinforced concentrically arranged flat, honed from two sides and assembled annular plates (Fig, 3) assembled with necessary gaps with holes, forming a system of channels for a pair of channels turned by outlet openings into the cavity between the disks l.

communicating with a branch pipe; Steam enters through a system of pipelines g connected to stationary: guiding nozzles B (Figs. 1 and 2) arranged sequentially around the circumferences between the rows of working ring plates d, and the nozzles directed to the plates d so that the steam jets are parallel to their planes and dissected by their outer and inner circles. The jets aimed at the outer circumference of plate d are tangents of an imaginary circle e ,. and jets acting from the inside, come at an angle to the tangent circle e (Fig. 4).

The subject matter of the invention.
