Description

Ship steam turbine module structure

The present disclosure relates to a steam turbine module structure for a ship having a steam turbine, a generator, and a condenser.

The main equipment required for a power plant using a steam turbine is, for example, a steam turbine, a generator, and a condenser. With respect to the installation of these major appliances, the steam turbine and the generator are installed on a common plate, and the condenser is generally installed below the steam turbine. For example, the condenser is installed separately below the steam turbine floor.

Generally, such a steam turbine generator is mounted on a LNG (Liquefied Natural Gas) line or a container ship, and is installed in the engine room by the layout.

On the other hand, there is a growing demand for installing a steam turbine generator on a deck of a ship in recent years. Depending on the type of ship, there are usually many devices mounted on the deck of the ship in general. Therefore, in order to mount the steam turbine generator system on the deck of the ship, it is necessary to simplify the installation work similarly to the riding machine.

In a conventional steam turbine generator in a terrestrial power generation plant, a technique for packaging a steam turbine power generation facility and a boiler as a reduction in installation space has been proposed (see Patent Document 1). In the power plant described in Patent Document 1, a steam turbine power generation facility (a steam turbine, a generator, and a condenser) is installed on the upper part of a steel-framed stand made of reinforcing steel, and a boiler And is packaged.

Japanese Patent Application Laid-Open No. 2003-106110

However, in the power plant described in Patent Document 1, the steam turbine and the condenser are arranged on the upper part of the steel-frame steel-frame stand. For this reason, it can not be applied to a downward exhaust steam turbine generally used in marine steam turbines. In the power plant described in Patent Document 1, a boiler is installed at the lower part of the steel-frame steel-frame foundation. However, in the ship steam turbine power generation facility, the boiler is often installed at a place different from the steam turbine facility installed on the deck, and the power plant described in Patent Document 1 can not be applied to such a case.

At least one embodiment of the present invention is an invention made under the circumstances of the prior art as described above and it is an object of the present invention to provide a steam turbine module for a ship which can simplify installation work on a deck of a ship of a steam turbine power generation facility Structure.

(1) According to at least one embodiment of the present invention, there is provided a marine steam turbine module structure,

A steam turbine module structure for a ship installed on a deck of a ship,

1. A steam turbine comprising: a steam turbine; a generator driven by the steam turbine; a condenser for condensing the steam discharged downward from the steam turbine; and a frame on which the steam turbine, the generator,

The above-mentioned frame is composed of a two-layer structure having an upper plate and a lower plate,

The steam turbine and the generator are installed on the upper plate and the condenser is installed on the lower plate so that the steam turbine, the generator, the condenser and the mount are modularized.

According to the steam turbine module structure for a ship described in (1) above, a steam turbine and a generator are installed on a top plate of a base of a two-layer structure, and a condenser is installed on a bottom plate of the base. It is possible to simplify the connection structure between the steam turbine and the generator by installing the steam turbine and the generator on the upper plate of the platform, and by installing the condenser on the lower plate of the platform, the steam exhausted from below the steam turbine Can be condensed. As a result, the steam turbine, the generator, and the condenser, which are main devices of the steam turbine power generation facility, are put into a single unit and can be modularized as a steam turbine power generation facility. This makes it possible to realize a ship steam turbine module structure that can simplify the installation work on the deck of the ship of the steam turbine power generation facility.

(2) In some embodiments, in the ship steam turbine module structure described in (1) above,

The condenser is configured to be installed on the lower plate so that the longitudinal direction of the condenser is along the axial direction of the steam turbine.

According to the embodiment described in (2) above, as compared with the case where the condenser is provided such that the longitudinal direction of the condenser is perpendicular to the axial direction of the steam turbine, the installation area have. This makes it possible to reduce the installation space of the steam turbine facility for ships installed on the deck of the ship.

(3) In some embodiments, in the ship steam turbine module structure described in (2) above,

Wherein the generator is provided on the upper plate so that the axial direction of the rotary shaft of the generator is parallel to the axial direction of the steam turbine,

In a case where one side is defined as one area and the other side is defined as the other area with respect to a line orthogonal to the axial direction of the steam turbine passing through the center position in the axial direction of the steam turbine of the upper plate, And the main body portion of the generator is configured to be installed in the other side region.

According to the embodiment described in (3) above, it is possible to dispose the generator along the longitudinal direction of the steam turbine when viewed in a plan view. Therefore, when viewed in plan, the width between one end in the width direction of the steam turbine and the other end in the width direction of the generator can be narrowed. In addition, although the steam turbine and the generator are heavy, the main body of the steam turbine is provided in one area of the line passing the center position of the top plate, and the generator is provided in the other area of the steam turbine and the generator. Weight balance can be easily made. Therefore, when viewed from the plane, the center of gravity of the entire structure of the steam turbine module for a ship can be brought close to the center position of the top plate, and the installation structure of the steam turbine module for a ship is suspended .

(4) In some embodiments, in the ship steam turbine module structure described in (3) above,

The turbine shaft of the steam turbine and the rotary shaft of the generator are connected through a reduction gear,

The synthetic center of gravity of the steam turbine, the generator, and the center of gravity of each of the reduction gears is configured to exist in the other area E2.

The main body of the condenser is disposed below the main body portion of the steam turbine. Therefore, the center of gravity of the lower plate side of the table is located in a region on one side where the main body portion of the steam turbine is installed than the center position of the upper plate. Accordingly, when the center of gravity of the composite gravity of the upper plate side is located in one side region, the center of gravity of the entire structure of the ship steam turbine module moves to one side rather than the center position of the upper plate together with the gravity center of the condenser. Therefore, as in the embodiment described in (4) above, since the center of gravity of the composite weight on the upper plate side is present in the other side region, it is possible to prevent the weight balance of the entire steam turbine module structure for the ship from being largely collapsed.

The outlet of the vapor introduction pipe is configured to have a circular shape.

According to the embodiment described in (5), when the steam outlet of the steam turbine extends in a direction orthogonal to the axial direction of the steam turbine, the longitudinal direction of the inlet of the steam inlet pipe is the same direction as the steam outlet of the steam turbine So that the steam discharged from the steam outlet can flow smoothly into the inlet of the steam inlet pipe. In addition, by making the outflow port of the vapor introduction pipe circular, it is possible to improve workability in connecting the connection pipe to the outflow port.

(6) In some embodiments, in the ship steam turbine module structure described in (5) above,

Further comprising a connecting pipe connecting an outlet of said steam inlet pipe and a steam inlet of said condenser,

The connection pipe is configured to be able to expand and contract in an axial direction and a radial direction of the connection pipe.

The temperature of the steam discharged from the steam turbine varies depending on the operating condition of the steam turbine. In addition, depending on the operating condition of the steam turbine, vibration may occur in the steam turbine. Therefore, according to the embodiment described in (6) above, it is possible to arrange the connecting tube, which is contractible and contractible in the axial and radial directions, between the vapor introduction pipe and the condenser, Can be absorbed in the connecting pipe, and also vibration from the steam turbine can be absorbed in the connecting pipe.

(7) In some embodiments, in the structure of a steam turbine module for a ship according to any one of (1) to (6) above,

Further comprising a gland condenser for condensing the gland steam of the steam turbine,

The gland condenser is provided on the upper plate so that the longitudinal direction of the gland condenser is along the axial direction of the steam turbine.

According to the embodiment described in (7) above, when the gland condenser is provided on the upper plate so that the longitudinal direction of the gland condenser is along the axial direction of the steam turbine, It can be arranged along the longitudinal direction of the turbine. Therefore, the width between the other end in the width direction of the steam turbine and the end in the width direction of the gland condenser can be narrowed, and the installation area of the stand can be reduced.

According to at least one embodiment of the present invention, it is possible to provide a ship steam turbine module structure that can simplify installation work on the deck of a ship of a steam turbine power plant.

Thus, the steam turbine 5 and the generator 10 are installed on the upper plate 21 of the two-layer structure supporting table 20, and the condenser 15 is provided on the lower plate 23. The steam turbine 5 and the generator 10 are provided on the upper plate 21 of the platform 20 so that the generator 10 can be driven by the power of the steam turbine 5, By installing the condenser 15 on the lower plate 23, the steam discharged from the lower portion of the steam turbine 5 can be condensed by the condenser 15. As a result, the steam turbine 5, the generator 10, and the condenser 15, which are the main devices of the steam turbine power generation facility, are put into one unit 20 and can be modularized as a steam turbine power generation facility. Thereby, it is possible to realize the ship steam turbine module structure (1) which can simplify the installation work on the deck (70a) of the ship (70) of the steam turbine power plant.

3, 4 and 5, the condenser 15 is arranged so that the longitudinal direction of the condenser 15 is the direction along the axial direction of the steam turbine 5, (Not shown).

[ The condenser 15 is located just below the steam turbine 5 and is disposed such that the longitudinal direction of the condenser 15 is parallel to the axial direction of the steam turbine 5. [ The condenser 15 is provided with a condenser main body portion 16 for condensing the steam discharged from the steam turbine 5 and allows cooling water for cooling the steam to flow at one longitudinal end portion of the condenser main body portion 16 And a cooling water pipe 17 is connected. The cooling water pipe 17 is connected to one longitudinal end portion of the condenser main body portion 16 and extends toward the other longitudinal end side of the platform 20 along the longitudinal direction of the condenser 15.

According to this embodiment, when the condenser 15 is provided on the lower plate 23 so that the longitudinal direction of the condenser 15 is along the axial direction of the steam turbine 5, It is possible to reduce the installation area of the table 20 when viewed from the plane as compared with the case where the condenser 15 is provided so as to be in a direction orthogonal to the axial direction of the steam turbine 5. [ Thus, the installation space of the steam turbine facility for a ship installed on the deck 70a of the ship 70 can be reduced. In addition, by making the condenser 15 parallel to the front and rear of the ship, it is possible to alleviate the influence on the inclination of the ship and to reduce the influence on the control of the liquid level.

In the above embodiment, the condenser 15 is disposed such that the longitudinal direction of the condenser 15 is parallel to the axial direction of the steam turbine 5. However, the present invention is not limited to this. At least the inclined angle of the longitudinal direction of the condenser 15 and the axial direction of the steam turbine 5 is less than 30 degrees so that the longitudinal direction of the condenser 15 is along the axial direction of the steam turbine 5.

Therefore, the center of gravity of the overall structure of the ship steam turbine module can be made closer to the center position of the upper plate 21 when seen from the plane, so that the ship steam turbine module structure 1 is hung up, It is possible to improve the installation property when installing it on the base 70a.

In some embodiments, the turbine shaft 5b of the steam turbine 5 and the rotary shaft 10a of the generator 10 are connected to each other through the reduction device 51. [ The decelerator 51 is connected between the tip end of the turbine shaft 5b connected to the rotor 5a2 of the steam turbine 5 and the tip end of the rotary shaft 10a of the generator 10 in the illustrated embodiment. The speed reducing device 51 is constituted by, for example, engaging a plurality of gears. For this reason, it is possible to adjust the generator rotation speed according to the frequency in the line.

In some embodiments, the synthetic center of gravity G1 obtained by synthesizing the center of gravity of each of the steam turbine 5, the generator 10 and the speed reducing device 51 is located in the other side region E2). ≪ / RTI > In the illustrated embodiment, the composite center of gravity G1 is at a position deviated from the line L to the other side region E2 as shown in Fig. The composite center of gravity G1 is located above the platform 20 as seen from the side of the ship steam turbine module structure 1 as shown in Fig. 4 and 5, the condenser main body portion 16 of the condenser 15 is disposed substantially directly below the main body portion 5a of the steam turbine 5. [ A cooling water pipe 17 along the longitudinal direction of the condenser 15 is connected to the other longitudinal side of the condenser body 16 of the condenser 15. The center of gravity G2a when viewed from the plane of the condenser main body portion 16 is located in the region E1 on one side with respect to the line L and the center of gravity G2b when viewed from the plane of the cooling water pipe 17 Is in the other-side area E2 than the line L. The center of gravity G2a of the condenser main body portion 16 and the center of gravity G2b of the cooling water pipe 17 are combined so that the center of gravity G2b of the condenser main body portion 16, G2 are displaced from the line L to the one side region E1. The composite center of gravity G2 is located below the base 20 as seen from the side of the ship steam turbine module structure 1 as shown in Fig. Therefore, the total composite center of gravity G3 of the equipment installed on the lower side of the platform 20 and the equipment installed on the upper side is located in the vicinity of the line L. Therefore, it is possible to prevent the weight balance of the entire steam turbine module structure 1 from being greatly collapsed.
