    The capacity of the condenser increases, since in the outlet pipe 3 there is a counterflow between the condensate, which drains down, and the residual steam, which goes up, and the heat exchange between them occurs due to direct contact, and thus provides additional condensation of the residual steam.
    The steam condenser, in addition to completely eliminating the conditions that can lead to the formation of a reverse flow, also provides additional protection against freezing, since the output coils of the coils 7 are washed by air, which is heated during the flow between two other coils of the same elements of the coils 7 and whose temperature is now well above ambient temperature.

    The invention relates to heat engineering and can be used in air-cooled steam condensers. The purpose of the invention is to increase the efficiency of the condenser. FIG. 1 schematically shows a vapor condenser. Cross-section; Fig, 2 - the same, side view, section; FIG. 3 is a section A-A in FIG. 1. An air-cooled steam condenser contains installed inclined distribution pipe 1, for condensable steam, connected to dispensing manifold 2 in the lower part, exhaust pipe 3, connected in the lower part to collector collector 4, and in the upper part to pipeline 5 for release of non-condensable gases. and steam residues through an ejector (not shown), a bundle of 6 parallel finned heat exchange tubes made in the form of a horizontally installed three-turn coil 7 with turns placed horizon flax and parallel to one another in successive rows relative to the flow of cooling air supplied by blower 8 perpendicular to the beam placed under the beam 6, the coils are connected in series along the condensed pair using two elbows 9 and 10 placed at an angle with a positive slope, heat exchangers the pipes are connected at one end with pipeline 1, and the other with pipeline 3, each of the coils 7 is connected to pipeline 1 with its turn, which contacts first with the cooling air flow, and from pipes by the conduit 3 with its turn, which comes in contact with the cooling air flow, with the possibility of forming a device with a cooling air device, and the steam condensers are mounted on the frame 11 in pairs with power from the common collector 2. The steam condenser works with a trace: this way. The steam enters from the collector 2 to the steam distribution pipe 1 and then to the coils 7, where the coolant is. is given and condensed, the condensate is discharged through inclined elbow fittings 9 and 10 into the exhaust pipe 3 and further into the collecting manifold 4. The condensable gases and steam residues enter the pipeline 5 and are sucked out of it. The air for cooling the bundle 6 of heat exchange tubes is supplied by the blower 8 from below and goes to the coils connected to the pipeline, then to the next and goes outside. The capacity of the condenser increases as in the outlet pipe 3 there is a countercurrent between the condensate that drains down and the residual steam that goes up, and the heat exchange between them occurs through direct contact, and thus additional condensation of the residual steam is ensured. In addition to completely eliminating conditions that can lead to reverse flow, the steam condenser also provides additional protection from freezing, as the output coils of the coils 7 are washed by the air that is heated by the other two coils of the same coils 7 and the temperature of which is now significantly higher ambient temperature. Claim 1. Air-cooled steam condenser containing a distribution pipe for condensable steam, an exhaust pipe, a bundle of finned heat exchanging pipes placed parallel to one another and connected at one end to a distribution pipe, and at the other end to an exhaust pipe, blower to create cooling air flow perpendicular to the beam, characterized in that, in order to increase -. ECOPOM1GCHNOSTI., Each pipe is curved to form a three-coil coil, the coils of which are placed horizontally and parallel to one another, the coils of each coil being connected sequentially, but along a condensable pair, by means of elbows placed at an angle with a positive slope.
