In the present embodiment, the exhaust duct 19 is configured to discharge the exhaust gas G1 upward.

Exhaust gas G1 discharged from the exhaust duct 19 of the gas turbine 11 is supplied to the boiler 5. The boiler 5 uses the exhaust gas G1 as a heat source to generate steam. The steam generated in the boiler 5 is sent to the steam turbine of the steam turbine power generator to drive the steam turbine.

As shown in FIG. 1, the combined cycle power generation system includes a plurality of gas turbine power generation devices 9 (two in this example). In the present embodiment, one boiler 5 is provided for one gas turbine power generation device 9. Therefore, as described above, the water boiler equipment 1 includes a plurality of (two in this example) boilers 5.

As shown in FIG. 3, each boiler 5 has an elongated shape in a plan view. These two boilers 5 are respectively in the longitudinal direction (hereinafter referred to as "boiler longitudinal direction") L1 of each boiler 5 and the width direction (hereinafter referred to as "boiler width direction") W1 orthogonal to the height direction H. The boilers are installed side by side so that the longitudinal directions L1 of the boilers are parallel to each other. In other words, each boiler 5 is arranged on the side of the other boiler 5 (direction facing W1 in the boiler width direction). Further, in this example, each boiler 5 is arranged so that the respective boiler longitudinal direction L1 is parallel to the longitudinal direction L2 of the hull 3 (hereinafter, referred to as “hull longitudinal direction”).

More specifically, in the illustrated example, the two gas turbine power generation devices 9 are arranged so that the axis C is parallel to the hull longitudinal direction L2, and are arranged in the width direction W2 of the hull 3.

As will be described in detail later, each boiler 5 is arranged above each gas turbine power generation device 9 so that the longitudinal direction L1 of the boiler 5 and the axial center C direction of the gas turbine power generation device 9 are parallel to each other. The arrangement direction of each boiler 5 with respect to the hull 3 and the gas turbine power generation device 9 is not limited to this example.

As shown in FIG. 4, specifically, the boiler 5 according to the present embodiment includes a boiler main body 21 configured as a heat exchanger that generates steam using exhaust gas G1 as a heat source, and a boiler support that supports the boiler main body 21. It includes a structure 23. The boiler main body 21 includes an evaporation pipe 25 for evaporating water and a drum 27 which is arranged above the evaporation pipe 25 and separates steam generated in the evaporation pipe 25 from water. In this example, each boiler 5 includes two drums 27, a high-pressure drum 27A and a low-pressure drum 27B. Although not shown, the boiler main body 21 may be appropriately provided with various known heat exchangers such as a superheater and an economizer in addition to the evaporation pipe 25 and the drum 27 described here. Further, the specific configuration of the boiler 5 is not limited to this example, and may be, for example, a once-through boiler without a drum.

The evaporation pipe 25 is covered with a boiler wall body 29 that forms a passage (flue) for the exhaust gas G1 that passes through the boiler 5. An exhaust stack 31 that opens upward is provided above the boiler wall 29. In this example, the exhaust stack 31 is provided substantially at the center of the boiler wall body 29 in the boiler longitudinal direction L1. The exhaust gas G2 that has passed through the inside of the boiler main body 21 (inside the boiler wall 29) is discharged to the outside from the exhaust stack 31. The boiler support structure 23 will be described later.

The boiler wall body 29 has an introduction portion 29a, a body portion 29b, and a lead-out portion 29c in this order from the bottom. The introduction unit 29a introduces the exhaust gas G1 from the exhaust duct 19 of the gas turbine 11. An evaporation pipe 25 is arranged inside the body portion 29b, and the evaporation pipe 25 and the exhaust gas G1 are brought into contact with each other. The lead-out unit 29c leads out the exhaust gas G1 to the exhaust pipe 31 connected to the upper portion thereof. The introduction portion 29a is formed in a substantially trapezoidal shape that gradually expands from the lower side to the upper side in a side view. The body portion 29b is formed in a substantially rectangular shape extending upward from the upper end of the introduction portion 29a in a side view. The lead-out portion 29c is formed in a substantially trapezoidal shape that gradually narrows upward from the upper end of the body portion 29b in a side view. Further, as shown in FIG. 1, in this example, the boiler wall body 29 has a shape in which the dimension in the height direction H is larger than the dimension in the boiler width direction W1. However, the shape of the boiler wall body 29 (boiler body 21) is not limited to this example.

Hereinafter, the support structure and the connection structure of the plurality of boilers 5 will be described in detail.

As shown in FIG. 1, the hull 3 has an upper deck 33. A closed space is formed below the upper deck 33, that is, between the upper deck 33 and the bottom of the ship, and the upper part of the upper deck 33 is an open space. In this embodiment, the boiler 5 and the gas turbine power generation device 9 are installed above the upper deck 33. Specifically, the gas turbine power generation device 9 is installed directly on the upper deck 33, and the boiler 5 is installed above the gas turbine power generation device 9.

The installation position of the boiler 5 with respect to the hull 3 and the gas turbine power generation device 9 is not limited to this example. For example, the boiler 5 may be installed directly on the upper deck 33 like the gas turbine power generation device 9, or may be installed below the upper deck 33.

In the illustrated example, a pedestal 35 for the boiler 5 is installed on the upper deck 33, and the boiler 5 is installed on the pedestal 35. The height dimension and width dimension of the gantry 35 are set to be larger than the height dimension and width dimension of each gas turbine power generation device 9, and the gantry 35 is arranged so as to straddle each gas turbine power generation device 9 in the width direction. There is. In this example, the gantry 35 is made of steel.

Specifically, in the present embodiment, each pedestal 35 (two pedestals 35 in this example) supporting each boiler 5 of the plurality of boilers 5 is formed as an integrated shared pedestal 37. More specifically, in this example, as shown in FIG. 5, the common pedestal 37 is a total of four pedestal side portions, two each arranged on both sides of two adjacent gas turbine power generation devices 9. It has a pillar member 39A, two pedestal intermediate pillar members 39B arranged between these two gas turbines 11, and a pedestal frame member 41 connected to the upper part of these six pedestal pillar members 39. ing. The gantry frame member 41 consists of a total of seven beams, three beams connecting two column members 39 on both sides and intermediate positions, and four beams connecting adjacent column members in the boiler width direction W1. It is formed from beams. Each boiler 5 is installed on two beams extending in the boiler width direction W1 of the frame member 41. In FIG. 5, the internal space of the boiler main body 21 of the boiler 5 is shown by hatching. In this example, the common gantry 37 is not provided with any beams other than the seven beams forming the gantry frame member 41.

In this way, by integrating the plurality of pedestals 35 corresponding to the plurality of boilers 5 into a shared pedestal 37, the entire pedestal 35 is formed as compared with the case where the pedestals 35 corresponding to each boiler 5 are separately provided. It is possible to reduce the total number of members and space required. However, the plurality of mounts 35 may be formed separately.

The boiler support structure 23 includes a plurality of column members 45 extending in the height direction H of the boiler 5 and a beam member 47 connecting adjacent column members 45. More specifically, as the pillar members 45 of each boiler support structure 23, two front pillar members 45A arranged on both sides of the boiler main body 21 at one end (left end in FIG. 5) of the boiler longitudinal direction L1. And two rear pillar members 45B arranged on both sides of the boiler main body 21 at the other end (the right end in FIG. 5) are provided. These front pillar members 45A and rear pillar members 45B are from the installation surface of the boiler 5 (in this example, the upper surface of the frame member 41 which is the installation surface on the frame 35) to the body portion 29b and the lead-out portion 29c of the boiler wall body 29. It extends to a position that almost corresponds to the boundary.

In the illustrated example, as the pillar member 45, a first intermediate pillar member 45C1 and a second intermediate pillar member 45C2 arranged at the L1 position in the longitudinal direction of the boiler sandwiching the exhaust stack 31 in a side view are further provided.

Further, as shown in FIG. 5, as the beam member 47 of each boiler support structure 23, the front beam member 47A connecting the two front column members 45A in the boiler width direction W1 and the two rear column members 45B are connected to the boiler width. A rear beam member 47B connected to the direction W1 is provided. Specifically, in the illustrated example, the front beam member 47A and the rear beam member 47B are located at substantially the center of the body portion 29b of the boiler wall body 29 in the height direction H, respectively, as shown in FIG. It is provided. In the illustrated example, the front beam member 47A and the rear beam member 47B are also provided at a plurality of height direction positions other than substantially the center of the body portion 29b of the boiler wall body 29 in the height direction H.

In the illustrated example, as beam members 47, a plurality of side beam members 47C connecting between the front column member 45A and the rear column member 45B are further provided on both sides of the boiler main body 21 in the height direction H. ing. In this example, each side beam member 47C is provided at the same height direction position as the corresponding front beam member 47A and rear beam member 47B.

The positions and numbers of the column members 45 and the beam members 47 constituting the boiler support structure 23 are not limited to this example, and may be arbitrarily selected.

The connecting member 7 is integrally formed with the beam member 47 of the boiler support structure 23, and a plurality of adjacent (two in this example) boilers 5 are connected to each other in the boiler width direction W1. In the illustrated example, as the connecting member 7, the front connecting member 7A integrally formed by being connected to each front beam member 47A of the two boilers 5 and the rear beam member 47B are integrally formed. A rear connecting member 7B is provided.

More specifically, as shown in the figure, each of the front and rear connecting members 7 and each beam member 47 integrally formed by being connected to the connecting member 7 are single. It is formed as a rod-shaped member 49 extending in a straight line.

However, the mode in which the connecting member 7 and the beam member 47 are integrally formed is not limited to this example. For example, as shown by the alternate long and short dash line in the figure, the connecting member 7 is provided at an intermediate position between both ends of the boiler 5 in the longitudinal direction L1, and each side provided on the opposite side of the two adjacent boilers 5. The boiler member 47C and the connecting member 7 may be integrally formed. In the illustrated example, a plurality of (two in this example) connecting members 7 are arranged at equal intervals in the boiler longitudinal direction L1, but one connecting member is located at the center position of the side beam members 47 in the boiler longitudinal direction L1. Only 7 may be provided. The integrally forming member of the side beam member 47 and the connecting member 7 may be provided in place of the integrally forming member at both ends, or may be additionally provided.

As shown in FIG. 1, the drum 27 of each boiler 5 is installed on a drum support 51 connected to two boilers 5 connected to each other by a connecting member 7. Specifically, as shown in FIG. 1, the drum support 51 is provided between the boiler main bodies 21 of the two boilers 5. Further, as shown in FIG. 4, the drum support 51 is a flat plate-shaped member provided on the front pillar member 45A and the rear pillar member 45B. In this example, the drum support 51 is provided at a position substantially corresponding to the boundary between the body portion 29b and the lead-out portion 29c of the boiler wall body 29. Further, the drum support 51 also serves as a beam member 47 that connects the plurality of column members 45 and the connecting member 7 that is integrally formed with the beam member 47.

Returning to FIG. 1, in the present embodiment, a drum support column 53 for supporting the drum support 51 is provided directly below each drum 27 in the drum support 51. In this example, each boiler 5 includes two drums 27, a high pressure drum 27A and a low pressure drum 27B. Therefore, a total of four drums 27 are installed on the drum support base 51, and a drum support pillar 53 is provided directly below each drum 27. Each drum support column 53 extends from the installation surface of the boiler 5 (in this example, the upper surface of the gantry frame member 41 which is the installation surface on the gantry 35) to the lower surface of the drum support pedestal 51.

By installing the drums 27 of each boiler 5 on the drum support 51 configured in this way, the entire boiler equipment B is connected so as to support each other in the upper part between the adjacent boiler bodies 21. The dimension of the height direction H can be suppressed. Therefore, the boiler 5 and the drum 27 included in the boiler 5 can be supported by a simple and compact structure.

The position where the boiler support 51 is provided is not limited to the above example as long as the drum 27 located above the evaporation pipe 25 can be installed. For example, the drum support 51 may be provided above the boiler main body 21. Further, the drum support column 53 may also serve as a precipitation pipe. When the drum support pillar 53 also serves as a precipitation pipe, for example, the upper end of the drum support pillar 53 penetrates the drum support base 51 and is directly connected to the drum 27, and the lower end of the drum support pillar 53 is installed on the boiler installation surface. It may be connected to a water pump. However, the structure supporting the drum 27 is not limited to these examples.

As shown in FIG. 4, in the present embodiment, in each boiler 5, the evaporation pipe 25 is extended along the boiler longitudinal direction L1 and along the hull longitudinal direction L2, and is in the boiler longitudinal direction L1. It is provided so as to incline from one side to the other. The reason why the evaporation pipe 25 is extended along the boiler longitudinal direction L1 is to reduce the number of joints of the evaporation pipe 25 as much as possible to reduce the cost. Further, the evaporation tube 25 is tilted in order to efficiently separate the gas-liquid mixed phase (saturated water), or the gas-liquid mixed phase is separated in a large circulation loop formed by the drum 27 and the evaporation tube 25. This is to circulate naturally.

FIG. 6 shows the water boiler equipment 1 according to another embodiment of the present invention. The water boiler equipment 1 according to the present embodiment is different from the embodiment shown in FIGS. 1 to 5 in the relative arrangement configuration of the two adjacent boilers 5. That is, in the present embodiment, the other boiler 5 (hereinafter referred to as "second boiler 5B") arranged on the side of one boiler 5 (hereinafter referred to as "first boiler 5A") is the second boiler. The longitudinal direction L1B of 5B is arranged in a direction substantially orthogonal to the boiler longitudinal direction L1A of the first boiler 5A. Hereinafter, this point will be mainly described with respect to this embodiment, and the description of the configuration common to the embodiments shown in FIGS. 1 to 5 will be omitted.

More specifically, the second boiler 5B is arranged on the side of the first boiler 5A at a substantially central position in the boiler longitudinal direction L1A of the first boiler 5A. In other words, these

boilers

5A and 5B are arranged in a T shape in a plan view. In this case, as shown in the figure, for example, the drum support 51 can be arranged at each of the two corners formed by the first boiler 5A and the second boiler 5B.

The position of the second boiler 5B with respect to the position of the first boiler 5A in the longitudinal direction of the boiler L1A is not limited to the central position. For example, as shown in FIG. 7 as a modified example of the present embodiment, even if the second boiler 5B is arranged at the end position of the first boiler 5A in the boiler longitudinal direction L1A on the side of the first boiler 5A. good. In other words, these

boilers

5A and 5B may be arranged in an L shape in a plan view. In this case, as shown in the figure, for example, the drum support base 15 can be arranged at one corner formed by the first boiler 5A and the second boiler 5B.

In the present embodiment, the first boiler 5A is arranged so that the boiler longitudinal direction L1A is parallel to the hull longitudinal direction L2.

According to the water boiler equipment B according to each of the above-described embodiments, at least one of the plurality of boilers 5 installed on the hull 3 that is constantly shaking is structurally constructed by using the other boiler 5. By adopting a structure that supports in the width direction, which is weak against the hull, it is possible to efficiently support the narrow hull 3 with a compact and simple structure.

In particular, as in the embodiment shown in FIGS. 1 to 5, two boilers 5 are arranged side by side so that their longitudinal directions are parallel to each other in the width direction, and these two boilers 5 are both. When the boilers are connected in the width direction by a connecting member integrally formed with the beam member of the boiler, the boilers 5 support each other in the structurally weak width direction, so that the boiler 5 is compact and compact on the narrow hull 3. A simple structure can provide a stronger support structure.

As shown in the embodiments of FIGS. 6 and 7, the two

boilers

5A and 5B may be arranged so that the respective longitudinal directions L1A and L1B are orthogonal to each other. According to this configuration, the hull 3 may be arranged. It becomes easy to adjust the arrangement of the boiler equipment B according to the arrangement of other equipment and equipment to be installed.

In the embodiment of FIGS. 1 to 5, as described above, the plurality of pillar members 45 of each boiler support structure 23 are the two front pillar members 45A arranged on both sides at one end in the longitudinal direction of the boiler. The beam member 47 of each boiler support structure 23 includes a front beam member 47A connecting the two front pillar members 45A, including two rear pillar members 45B arranged on both sides at the other end. The connecting member 7 includes a rear beam member 47B that connects the two rear column members 45B, and the connecting member 7 includes a front connecting member 7 integrally formed with the front beam member 47A of the plurality of boilers 5, and the rear beam. It includes a rear connecting member 7 integrally formed with the member 47B. With this configuration, while each boiler 5 is effectively supported by the boiler support structure 23, the boilers 5 are connected to each other at both ends of the boiler longitudinal direction L1 to effectively suppress the number of connecting members 7. 5 can be supported. Further, in the installation work of the boiler equipment B, since the beam member 47 and the connecting member 7 can be attached at the same height, the installation work is made more efficient and the installation cost is reduced.

In the embodiment of FIGS. 1 to 5, the connecting member 7 and each beam member 47 integrally formed on the connecting member 7 are formed as a single linear rod-shaped member 49. Therefore, the boiler 5 can be supported with a more compact and simple structure. Further, the common use of the members makes the installation work of the boiler equipment B more efficient.

In each of the above embodiments, the drum 27 of the boiler main body 21 is installed on the drum support 51 connected to the two boilers 5 connected to each other, and the drum support is directly below the drum 27 on the drum support 51. A drum support column 53 that supports the base 51 is provided. With this configuration, it is possible to both connect the boilers 5 and support the drum 27 while effectively utilizing the limited space above the adjacent boilers 5.

In the embodiments of FIGS. 1 to 5, each boiler 5 is parallel to the longitudinal direction L1 of each boiler 5 in the hull longitudinal direction L2, that is, the direction in which the swing angle is smaller than the width direction W2 of the hull 3. It is arranged like this. Therefore, the boiler 5 can be supported by a compact and simple structure while suppressing the influence of the shaking of the hull 3 on the boiler 5. However, the installation direction of each boiler 5 with respect to the hull 3 is not limited to this.

In each of the above embodiments, the boiler body 21 of at least one boiler 5 of the plurality of boilers 5 includes an evaporation pipe 25 for evaporating water, and the evaporation pipe 25 is along the longitudinal direction L1 of the boiler 5. And is provided so as to incline from one of the longitudinal directions L1 of the boiler 5 toward the other. According to this configuration, the evaporation pipe 25 is extended along the longitudinal direction of the hull 3 which is less affected by the swing of the hull 3, and is inclined in this direction. It is possible to suppress the influence of the fluctuation of.

In each of the above embodiments, a plurality of boilers 5 are arranged above the upper deck 33 of the hull 3. According to this configuration, the hull 3 can be efficiently supported by a compact and simple structure on the upper deck 33 where the hull 3 has a large sway and there is no ship wall around it.

In each of the above embodiments, since the boiler 5 is arranged above the gas turbine power generation device 9 via the gantry 35 as described above, the boiler equipment B sways due to the sway of the hull 3 on the water. Therefore, it is particularly necessary to firmly support each boiler 5 in the width direction W1. Therefore, in this case, by connecting the adjacent boilers 5 with each other by the connecting member 7 and supporting the boilers 5 with each other, there is a great merit that the boilers 5 can be supported with a compact and simple structure. The boiler 5 may be provided above not the gas turbine power generation device 9 but another device installed on the hull 3, for example, a steam turbine power generation device. Further, as long as each boiler 5 of the boiler equipment B is installed on the hull 3 (for example, even if it is installed directly on the upper deck 33 or on the bottom of the ship), the hull 3 is always shaken. Since it is affected by the motion, even if the boiler equipment B is not arranged above the gas turbine power generation device 9, it is an advantage that the boilers 5 are supported by connecting a plurality of boilers 5 by a connecting member 7. Is obtained.

Further, in each of the above embodiments, the boiler equipment B is shown as an example of being one component of the combined cycle power generation system, but the configuration of the combined cycle power generation system is not limited to the above example. Further, the system including the boiler equipment B installed on the hull 3 is not limited to the combined cycle power generation system.

As described above, the preferred embodiment of the present invention has been described with reference to the drawings, but various additions, changes or deletions can be made without departing from the spirit of the present invention. Therefore, such things are also included within the scope of the present invention.
