- the single-shaft combined cycle plant is a power generation facility with excellent performance and operability.Recently, as the capacity of a single gas bin increases, the steam turbine also needs to be heated to a higher temperature with the aim of further improving efficiency. The capacity is increasing.
- Figure 1 is a conceptual diagram that shows an example of the shaft configuration of a conventional single-shaft combined cycle plant that has a relatively small capacity and a non-reheat steam bin with a low main steam temperature.
- a gas bin 2 directly connected to the compressor 1 is connected to a generator 4 by a rigid coupling 3, and a steam turbine 6 is connected to the generator 4 via a diaphragm coupling 5. Then, a thrust bearing 7 is provided outside the compressor 1 and the steam turbine 6. Have been killed.
- the gas bin and the steam bin do not affect each other and can be designed and manufactured as independent shafts.
- the steam turbine is relatively small in size due to its relatively small capacity, the centrifugal force of the rotor blades of the low-pressure steam turbine is small, and the main steam temperature is not high. It can be produced with only one rower.
- the diaphragm coupling 5 used in Fig. 1 has a very long transmission capacity, and in practical use, there are many problems such as noise and windage.
- a gas bin, a steam turbine, and a generator are connected by a rigid coupling 3 as shown in FIG.
- the thrust bearing 7 is provided only at one point in the shaft portion of the compressor 1 of the gas bottle. Then, in order to minimize the difference in elongation between the stationary part and the rotating part of the steam bin, the steam bin 6 is located between the compressor 1 and the generator 4 of the gas turbine near the thrust bearing 7.
