Description

The present acquisition is related to surface condensers for thermal installations.

A feature of the proposed: condenser is the use of a shield with holes and passing heating steam through the condensate in order to free it from air.

FIG. 1 shows the proposed capacitor; FIG. 2-scheme of steam supply.

In the upper part of the condenser housing 1, spent steam from a low-pressure turbine is supplied through a pipe 2. In the front and rear walls of the hull, bundles of cooling pipes 3 and water chambers with connections for supplying and discharging cooling water are reinforced.

The steam-air mixture is sucked from two sides through special nozzles 5.

In the lower part of the body there is a shield 6 with openings that are continuously filled with condensate. A deaeration chamber 4 is placed under the shield, also always filled with condensate, through which heating steam passes from a pipe system consisting of a main steam supply pipe 7 (Fig. 2) and processes 8 with three rows of holes 9.

Condensate-free condensate is discharged through nozzle 10. Condensate level in chamber 4 is maintained by a float regulator 11 connected to a valve 12 regulating the supply of additional warm water through pipeline 14. The lower part of the float chamber 13 communicates with water and the top part with steam chamber / condenser cavity.

The turbine short circuit steam enters through the nozzle 2 into the condenser body, passes between the cooling tubes 5, and in the form of condensate continuously fills the shield 6. Next, the condensate through the holes in the shield merges as a rain curtain into the chamber 4.

Heating steam (exhaust steam from auxiliary mechanisms), flowing from the holes of the processes 8, passes through the condensate: i heats it to the boiling point. The amount of heating steam corresponds to the amount of condensate supercooling. This correspondence is maintained by means of a thermostat.

Excess steam condenses when it comes in contact with streams of condensate flowing out of the openings of the shield 6.

The subject of the invention is a surface condenser, characterized in that, for the purpose of de-aeration, there is condensate in it by passing heating steam through condensate under cooling beams.

A perforated shield mounted continuously; condensate draining through its openings in the form of rain, condensing an excess amount of heating steam.
