Description

one

The invention relates to a power system and can be used in the devices of steam generators with the evaporation of a liquid with a decrease in its pressure.

The purpose of the invention is to improve the quality of steam by reducing the spray drift.

The drawing shows the proposed steam generator.

The steam generator contains a cylindrical housing 1 with a steam discharge pipe 2 on the side surface and a conical partition wall 3 coaxially mounted in the housing 1 and the central evaporation nozzle with the inlet and outlet sections 4 and 5, respectively, in the form of truncated cones, coupled with smaller bases. The conical partition 3 is made double-walled with an inner annular cavity 6. The truncated cone of the output section 5, as well as the walls of the conical partition 3 are made perforated, and the steam discharge pipe 2 of the housing 1 is led into the cavity of the latter and connected to the annular cavity 6 of the partition 3, the perforations are made in the form of holes 7 in the exit section 5, as well as in the outer and lower walls of the partition 3. The inlet section 4 of the evaporation nozzle is tightly connected to the side wall of the housing 1 and forms with it a drainage chamber 8, providing hydrochloric drain pipe 9. A steam generator is also provided with inlet and outlet conductive conductive pipes 10 and 11 and between the outlet portion of the nozzle 5 and the side wall of the housing 1 there is formed a slit gap 12,

The steam generator works as follows.

The liquid 5, heated to a temperature close to the saturation temperature, is fed through the inlet pipe 10 into the inlet section 4 of the evaporation nozzle, accelerates and boils due to a decrease in static pressure. The steam through the holes 7 in the outlet section 5 of the nozzle and the outer wall of the conical partition 3 enters the cavity 6 and is discharged through the steam outlet 2 to the consumer. The vapor-separated liquid flows into the drainage chamber 8 and is discharged through the drainage port 9. The main water flow is discharged through the drainage pipe 11. Part of the liquid that enters the inner wall of the conical partition 3 is removed through the slit gap 12 and

then through pipe 11.
