Description

  The present invention relates to a condenser installation for bypassing a steam turbine and directing a steam flow directly to the condenser.

  Generally, in a condenser used in a power plant, in addition to steam discharged from a turbine during normal operation, steam bypassing the turbine may be directly introduced to be cooled and condensed. Bypass steam from such a turbine bypass system is introduced into the condenser as surplus steam when the boiler is started up or when a load interruption of the generator occurs due to an accident in the power transmission system during operation of the power plant. .

  At the start of the power plant, steam from the boiler is directly introduced into the condenser and condensed in the turbine bypass system until steam conditions that allow ventilation to the turbine are obtained. This is because it is advantageous for quick start-up to recover the steam generated in the boiler without throwing it out of the system as much as possible. Also, when a load trip is performed due to an accident in the power transmission system and a turbine trip occurs, steam generated in the boiler is directly guided to the condenser to prevent the turbine from accelerating. In these cases, the condenser needs to condense large volumes of turbine bypass steam.

  FIG. 7 is a system configuration diagram showing a schematic system of the turbine bypass device. The high-pressure and high-temperature steam generated in the steam generator (boiler) 1 passes through the main steam pipe 2 and is supplied to the turbine 4 through the steam control valve 3. The steam supplied to the turbine 4 performs work in the turbine 4 and drives the generator 5. The steam that has performed the work is discharged to the condenser 6, where it exchanges heat with seawater or the like passing through the inner surface of the cooling pipe 7. It is condensed and becomes condensate. This condensate is boosted by a condensate pump 8 and sent to a low-pressure feed water heater 9, and further boosted by a feed water pump 11 driven by a feed pump driving turbine 10, and then steam is generated through a high-pressure feed water heater 12. Reflux to vessel 1.

  Further, a turbine bypass steam pipe 13 that bypasses the turbine 4 is provided between the main steam pipe 2 and the condenser 6, and the turbine bypass steam pipe 13 is provided with a bypass valve 14 and a pressure reduction and temperature reduction device 15. . Although only one system is shown in FIG. 7 for the turbine bypass steam pipe 13, a plurality of turbine bypass steam pipes 13 are usually provided. The temperature reducing and decompressing device 15 decompresses and reduces the temperature of the turbine bypass steam flowing through the turbine bypass steam pipe 13, and includes a porous tube type, cone type, and shower type temperature reducing and decompressing device 15.

  FIG. 8 is a structural diagram of a perforated tube type pressure reducing and reducing device 15 a installed in the condenser 6. A plurality of through holes 18 having a size of 0.5 mm to 30 mm are provided in the pipe 17 introduced into the condenser 6, and the steam flow in the pipe 17 is passed from the through holes 18 to the outside of the pipe 17 (inside the condenser 17 ) To reduce the temperature of the turbine bypass steam flow under reduced pressure. In the perforated tube type pressure reducing and temperature reducing device, the introduction of the turbine bypass steam flow into the condenser 6 has a simple structure because only the perforated tube is used.

  FIG. 9 is an explanatory view of a cone-type decompression and temperature reduction device 15b installed in the condenser 6, FIG. 9 (a) is a structural view, and FIG. 9 (b) is a perspective view of a sacrificial material. As shown in FIG. 9 (a), the cone-type decompression and temperature reduction device is provided with a cone pipe part 19 at the connection part of the turbine bypass steam pipe 13 into the condenser 6, and the cone pipe part 19 is The cross-sectional area of the pipe at the junction with the condenser shell (condenser wall) is formed so as to expand toward the downstream of the flow path. This reduces the temperature of the turbine bypass steam flow under reduced pressure. Furthermore, the turbine bypass steam flow collides with the sacrificial material installed in the condenser 6 to reduce the temperature under reduced pressure. As the sacrificial material, as shown in FIG. 9B, a tubular sacrificial material 20a, a shaped steel sacrificial material 20b (for example, an H-shaped rope), a plate-shaped sacrificial material 20c, and the like are used. In addition, although the shape rope sacrificial material has shown the H shape rope in the figure, the shape in particular is not ask | required.

  FIG. 10 is a structural diagram of a shower-type decompression and temperature reduction device 15 c installed in the condenser 6. The pipe 17 introduced into the condenser 6 is provided with a plurality of through holes 18 having a size of 0.5 mm to 30 mm, and the pipe 17 is partitioned in the condenser 6 by using, for example, a steel plate. It is installed in the part 21. The steam flow in the pipe 17 is discharged from the through-hole 18 to the outside of the pipe 17 (inside the condenser) and diffused into the partition portion 21. Furthermore, a plurality of through holes 22 having a size of 0.5 mm to 30 mm are provided on one or more of the outer surface and the inner surface of the partition part 21, and the steam flow in the partition part 21 from the through hole 22. Is discharged into the condenser 6. This reduces the temperature of the turbine bypass steam flow under reduced pressure.

  By the way, also in the above-described perforated pipe type pressure reducing and reducing device 15a, the turbine bypass steam flow in the turbine bypass pipe 13 is discharged directly from the through hole 18 into the condenser, so that the steam flow rate when released is high. In addition, since the steam pressure is high, it is difficult to install structural members inside the condenser in the vicinity of these through-holes 18 although the sacrifice materials 20a, 20b, and 20c are not installed as in the cone type.

  Therefore, in the shower-type decompression and temperature reduction device 15c, the vapor discharged from the through hole 18 of the perforated pipe is once reduced in the flow rate and pressure in the partition part 21, and then again from the through hole 22 into the condenser. It is intended to be released. By doing in this way, even if the vapor flow discharged from the through hole 22 of the partition part 21 directly collides with the structural member inside the condenser, the flow rate and pressure are reduced so as not to damage the structure. It is done.

  However, in the perforated tube pressure reducing and reducing apparatus 15a shown in FIG. 8, a sufficiently wide space is required in the condenser 6 to decelerate the turbine bypass steam flow discharged from the plurality of through holes 18. . Normally, the turbine bypass steam flow discharged from the pipe 17 has a structure that directly collides with the condenser body plate, and a main structure cannot be installed around the pipe 17. Therefore, although the structure of the perforated tube itself is simple and rational, the perforated tube type pressure reducing and temperature reducing device creates a useless space used only for decelerating the turbine bypass steam flow inside the condenser 6.

  Further, in the cone type decompression and temperature reduction device 15b shown in FIG. 9, the structure itself is simple and rational like the perforated pipe type, but the turbine bypass steam flow introduced into the condenser 6 is sufficiently decelerated. Therefore, it is necessary to install the sacrificial material 20 for making the turbine bypass steam flow collide with the condenser 6. In many cases, the sacrificial material 20 also serves as a reinforcing material for the condenser 6. In this case, the sacrificial material 20 is worn or thinned by collision with the turbine bypass steam flow. A thick-walled member is used. Therefore, in the cone type, the structure itself is simple and reasonable, but the members in the range where the turbine bypass steam flow collides are thinned by the turbine bypass steam flow. I have to be.

  Furthermore, in the shower-type decompression and temperature reduction device 15c shown in FIG. 10, the turbine bypass steam flow discharged from the perforated pipe is further diffused in the partition portion 21, and therefore the decompression and temperature reduction capability is sufficient. As compared with the perforated tube type or the cone type, a complicated structure is obtained because the partition portion 21 is installed in the interior of the unit 6.

  On the other hand, when the turbine bypass steam flow is introduced into the condenser 6, the turbine bypass steam flow is introduced into the condenser 6 by using all of the plurality of turbine bypass steam pipes 13 and the pressure reduction and temperature reduction devices 15. However, an appropriate amount of turbine bypass steam flow is adjusted by opening and closing the bypass valve 14 according to the load of the plant and introduced into the condenser 6. Therefore, the plurality of turbine bypass steam pipes 13 and decompression / temperature reduction apparatuses 15 are used differently, and the turbine bypass steam pipe 13 and the decompression / temperature reduction apparatus 15 that are frequently used are frequently deteriorated by steam, and the turbine bypass that is less frequently used. The steam pipe 13 and the decompression and temperature reduction device 15 are less deteriorated by steam.

  Conventionally, the turbine bypass steam flow is introduced into the condenser 6 by using any one of a multi-pipe type, a cone type, and a shower type regardless of the frequency of use. It was. In this method, regardless of the frequency of use, since all the decompression and temperature reduction devices 15 have the same structure, the decompression and temperature reduction devices 15 that are less frequently used have an over-specification structure.

  The objective of this invention is providing the condenser equipment which can aim at rationalization of the pressure reduction and temperature reduction apparatus of a turbine bypass steam flow.

  The condenser equipment of the present invention discharges a turbine bypass steam flow from a plurality of through holes provided in a pipe for introducing the turbine bypass steam flow bypassing the turbine into the condenser. Turbine bypass steam is produced by a cone pipe part where the cross-sectional area of the joint between the condenser pipe shell and the perforated pipe type pressure reduction and temperature reduction device that reduces the temperature and introduces it into the condenser is expanded in the downstream direction of the flow path. Cone-type depressurization and temperature reduction device that reduces the temperature of the flow and lowers the pressure of the turbine bypass steam by causing it to collide with the sacrificial material installed in the condenser to reduce the temperature of the turbine bypass steam and introduce it into the condenser And the turbine bypass steam flow is discharged from a plurality of through holes provided in a pipe for introducing the turbine bypass steam flow into the partition section partitioned in the condenser, and the temperature of the partition section is reduced.

Or two decompression / temperature reduction devices.

  According to the present invention, a turbine tube bypass steam flow decompression and temperature reduction device is combined with a perforated tube type, a cone type, and a shower type, and a turbine bypass steam flow decompression and temperature reduction device suitable for the frequency of use is installed. Since the flow is introduced into the condenser, it is possible to provide a condenser facility in which the decompression and temperature reduction device is rationalized.
