Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ground-mounted or floating package type power generation equipment that can be transported by floating.

Traditionally, the construction of a thermal power plant starts with civil engineering work at the site where the power plant will be constructed, then constructs the foundation for the turbine generator,
Construction of the turbine building, construction of the boiler steel frame, raising of the boiler drum, and installation of various equipment The main components were installed in line with the progress of civil engineering and turbine building construction.

At sites with poor local installation conditions, these installation works require a long period of time and have a large impact on power plant construction prices.

Furthermore, it is important to transport and bring in each element of the power plant's component equipment in accordance with the installation period, which increases transportation costs.

In particular, securing skilled engineers is a problem for power plants built in underdeveloped areas.

In contrast, recently, power plant components such as boilers, turbines, generators, transformers, and their auxiliary equipment, as well as turbine buildings, have been installed on floatable platforms, manufactured and assembled in one huge package in a factory. This package is transported using a submersible purge system near the construction site of the power plant (by sea, rivers, etc.) and prepared in advance.
It was towed to the installation site where civil engineering foundation work was completed.

By injecting the ballast into the ballast tank installed on the ship's platform, and then backfilling the surrounding area and connecting it to electricity, water, fuel equipment, etc. outside the package, the on-site installation period can be greatly reduced. A packaged power generation plant system is being considered, which shortens the production time and allows the production of power generation equipment with sufficient quality control within the factory.

The package type power generation equipment will be explained below using the drawings.

It is a sectional view (front view) along ll-In.

In the figure, reference numeral 1 is a boat platform, which has a ballast tank 1' and is manufactured in a factory dock like a normal ship.
And above is the boiler 2, which is a component of the power plant. turbine 3

Most of the power plant components such as the emergency power generation equipment 19 are mounted and configured as one huge package P.

20 in the figure is a turbine generator building for protecting these devices.

Each of these devices constituting the cage is manufactured in a short period of time under strict control at a factory, and then assembled and mounted on the ship's platform 1.

FIG. 4 is a diagram showing a state in which the power generation package P is transported on water. In FIG. 91, P is the power generation package, and B is a submersible purge for mounting the power generation package P.

Further, T is a towing boat for towing this submersible purge B, and S is a waterway, such as the sea.

In this way, the power generation package is towed close to the power plant construction site by the tugboat T.

In this way, packaged power plants can be manufactured and assembled in bulk at the manufacturer's desired location, including the power generation plant equipment and the building that houses it, and can be installed anywhere in the world that can be transported by water. .

It is clear that the above-described power generation package can be used as a mobile power station, instead of being fixedly installed on land as described above, by being fixed floating on the water and transmitting the generated power to land for a desired period of time. be.

However, when installing multiple power generation packages equipped with generator buildings, each power generation package is equipped with an independent generator building, so it is difficult to install multiple power generation packages as a packaged power generation facility. However, there is a drawback that each generator building of a multiple power generation package does not become one shared power generation equipment building.

This means that, in addition to ensuring safe operation as a power plant with multiple units installed, it is impossible to monitor the entire power plant, and this results in extremely poor performance in maintenance and inspection.

That is, a skilled operator must be assigned to each power generation package for operation, and independent maintenance and inspection equipment is required for each power generation package.

It is nearly impossible to require a large number of such skilled operators and maintenance and inspection equipment for a power plant built in an underdeveloped area.

Therefore, these technical solutions have strong (desired results).

The present invention has been made in view of the above-mentioned problems, and enables safe operation of the entire power plant in a package type power plant in which a plurality of power generation packages are installed. The objective is to obtain a pancage-type power generation facility that can easily perform everything from monitoring to operation and maintenance inspection.

The control room, which is set up as a sub-package within the generator building, is arranged alternately with the power generation packages that are distributed adjacent to each other.

Two sets of central control rooms are placed facing each other at a predetermined location for power plant construction, and the adjacent walls of the two control rooms are removed.
The two control rooms are connected to form a common central control room for two adjacent power generation units after completion.

The present invention will be described below with reference to an embodiment shown in FIGS. 5 and 6.

Figure 5 shows the emission 1ti? shown in Figure 1? The control room 17 of the hackage P is arranged adjacent to the power generation pancage P1. The two packages P, , P2 are arranged alternately in P2.
After arriving at the power plant, necessary parts of the walls of the adjacent control room 17 and generator building are removed, and the cutting plane shows the state in which the control room 17 and packages P, P2 are connected and connected. FIG. 6 shows a cross-sectional view (front view) taken along the straight line VI-Vl in FIG. 5.

Normally, when two power generation packages P of the same shape are installed, each power generation package is equipped with an independent generator building 20, so the generator buildings 20 have two sets of shapes. Furthermore, two sets of control rooms 17 will be installed at separate locations.

As mentioned earlier, this means not only the safe operation of the power plant, but also the monitoring, maintenance and inspection of the entire power plant.
Very inefficient.

Therefore, in the present invention, the control room 17 is arranged alternately between the power generation packages P1 and P2, and Pl, P2
After the two power generation packages arrive at the power plant, walls that need to be removed (not shown) among the adjacent walls of the control room 17 and generator building 20 are removed, and the walls of the control room 17 and generator building 2 are removed.
0 will be connected and combined to finally form one power plant building, and two sets of power generation units placed next to each other) P,
l P2 to form a set of common central control rooms 17'.

Needless to say, by creating a set of common central control rooms 17', it is possible to operate not only the entire power plant, but also to operate it effectively, even when it comes to safe operation.

As explained above, according to the present invention, even if multiple power generation packages are installed, it is possible to not only operate the power plant safely but also to monitor and control the entire power plant effectively. This has the effect of enabling efficient operation and maintenance.
