SU62727A1 - Steam separating device for locomotive boiler - Google Patents

Description

Already known steam separating devices with the use of fenders, devices for scouring the foam and subsequent fine separation inapa.

The proposed steam-separating device is distinguished by its use as a device for the fine separation of two pipes installed on both sides of the steam boiler and located outside the boiler.

Both pipes are connected to a central pipe, through which steam is supplied to the shut-off valve.

FIG. 1 shows a longitudinal section of the proposed steam-separating device; in fig. 2 is the same cross section and in FIG. 3 - device plan.

Breaker shields / serve to pre-release water particles from the steam flow. The lower breaker shield prevents moisture from being thrown into the suction bowl during longitudinal water level fluctuations.

To destroy the foam, four erosion troughs 3 are located on the plane of the highest water level. Feed pipe 2 is fed to the middle troughs through pipe 2, which is drained from them through the edges into the water space of the boiler. To be able to be placed between the pulls (not shown in the drawing), the troughs have a figured shape. The foam formed in the boiler, falling on the surface of the feed water that is cleaner and cooler than the boiler water, is destroyed. The main steam stream enters the wash troughs after it passes through the fenders. An insignificant share of the steam formed in the area of washing tanks does not have a noticeable effect on the separation process.

From the space above the scrubbing troughs, the steam enters the sukhoparnik.

For the final steam trap, a double separator is installed outside the boiler.

Steam rises to the upper part of the steam chamber, splitting into two streams, enters the side chambers formed by the shields 4. When

No. 62727-2

when entering the chamber, the container makes a sharp turn of 90 °, while some of the moisture should be separated and through drainage pipes 5 return to the water flow. From the chambers, the steam enters two pipes 6. At the ends of the pipes 6 there are cones 9 with drainage pipes // through which the separated moisture is directed into the water-space of the boiler.

From the pipes 6, the steam enters the pipes 7, and from them enters the pipe 8, which is connected to the shut-off 10. The moisture is separated from the steam in the pipes (5 occurs due to the formation of a water film on the walls.
