Abstract

The invention makes it possible to reduce the metal content of the preheater and increase its efficiency. The chamber (K) 7 is formed by a vertical partition 8 and a horizontal sheet 9 with flare 10 and part of the main perforated plate (PT) 6. K, serving as a evaporator cooler, is installed under the PT in the water supply zone, and the outlet 5 of the vapor-air mixture is located inside K. The size of the perforation of the plate is chosen from the condition that provides close to the optimal dimensions of the heater at its maximum performance. The presence of one PT, on which cold water is located, drastically reduces the possibility of boiling it and carrying moisture into the flow part of the turbine in the event of a vapor pressure drop. This allows refusal of check valves, increase of steam pressure and heating of water in the preheater. I il. G 75 SLE JV CO with “i

The invention relates to a heat power supply to sheet 9, finally to a horse, in particular to heat exchangers — is densed, and insoluble gases are cooled by a mixing type. They are discharged and vented through pipe 5. Thus

The aim of the invention is to reduce the image, the chamber 7 serves as the cooling of the metal content of the preheater and the rise of the evaporator. For pressure equalization

the effectiveness of his work. above the main plate 6 and under it, as well as

The drawing shows a regenerative ventilation of the vapor space of the heating heater, general view. Nozzles 11 are pressed.

Regenerative heater consists of the allocation of a certain area of the perforated housing 1 with pipes 2 and 3 according to the main plate (0.1–0.3% of all steam and water extraction, pipes of the perforation area) for the steam cooler and 5 respectively -determining taking into account the magnitude of the velocity of the ground mixture of the main perforated container at the entrance to the jet beam and the output of the reel 6, the chamber 7 installed under it, as well as the value of the steam velocity of the main perforated plate b in the zone of the entrance to the cooler (chamber 7) . The choice of the water inlet nozzle 3 and the specified up to 4 specified ratio provides for a near-installed vertical-to-optimal dimensions of the heater by a partition 8 and a horizontal perforated plate at its maximum capacity of sheet 9 with flared 10 and part of the base.

perforated plate 6, and the presence of a single plate, on which the cold water is perforated on the last perforation area, drastically reduces the potential of 1–0.3 of the perforation area of the main 20;

pipe 3 and enters the main per-Formula of the invention for a preformed plate 6. Most of the water 70-90% is discharged through perforations into the regenerative heater, plate 6 in the lower part of the body 1, the body with the steam inlets and the rest through the part of the perforation - water, water and steam-air mixture, plate 6 into chamber 7, then to the main perforated plate, a separate perforated sheet 9 with beads-chows, so that, in order to reduce metal 10 and also the lower part of the capacity and increased efficiency, it is housing 1. Steam enters the housing 1 packed with a chamber installed under the main branch pipe 2, washes water jets, a perforated plate flowing out into the zone forming from the perforation of the main tray 6, water of water and formed additionally condenses on them and together with the flow-restored vertical septum, the water is drained into the lower part of the housing 1 and the horizontal flared sheet and is discharged from the latter through the nozzle 4. A non-part of the main perforated plate condensed with a portion of the air-steam 40 than the perforation area of the last co-mixture enters the chamber 7 through the gap between -EtO, -0.3 of the perforation area by the flare 10 and the pipe of the subannular plate, and the outlet of the steam-water 3, where steam is, the passage through the water jets The air mixture is located inside the chamber.
