Embodiment 1
[0040] pass figure 1 Example 1 of the present invention will be described. figure 1 A structural diagram showing a gas turbine power generation system utilizing solar heat, in which a spraying device that sprays high-pressure hot water generated by solar heat is applied to the gas turbine power generation system.
[0041] exist figure 1 Among them, the gas turbine power generation system using solar heat in this embodiment is roughly composed of a gas turbine device 100, a heat collector 200 that collects solar heat to generate high-pressure hot water, and a spraying device that sprays the high-pressure hot water generated by the heat collector 200 on the intake air. 300 constitutes.
[0042] In the gas turbine plant 100 , an air intake duct 6 is provided on the upstream side of the compressor 1 . In addition, an air intake chamber (not shown) for taking in air may be provided on the upstream side of the air intake duct 6 . Atmospheric air 5 is introduced into the compress...
Embodiment 2
[0131] Next, pass Figure 5 The structure of Embodiment 2 of the present invention will be described.
[0132] Figure 5 is characterized in that, in order to suppress the figure 1 The heat storage tank 40 is set according to the variation of the sunlight in the solar radiation. and figure 1 The different system structures are shown below.
[0133] A branch pipe 44 is provided in the piping 28 for taking out high-pressure hot water from the heat collecting pipe 27 . A heat storage tank 40 is provided downstream of the branch pipe 44 via a flow rate adjustment valve 41 and piping 45 . Downstream of heat storage tank 40 , delivery pump 42 , pipe 47 , pressure regulating valve 43 , and pipe 48 are provided via pipe 46 , and pipe 48 is connected to pipe 30 downstream of pressure regulating valve 29 .
[0134] In this way, in this embodiment, equipment and piping are connected so that the high-pressure hot water generated in the heat collecting pipe 27 of the heat collecting ...
Embodiment 3
[0140] Then, use Figure 13 An example in which solar heat is utilized in a gas turbine system that drives driven equipment other than a generator will be described. That is, in Embodiment 1, solar heat is utilized in the gas turbine power generation system, but in this embodiment, solar thermal energy is utilized in the gas turbine system that is a drive device for load equipment such as pumps and compressors. In addition, a two-shaft gas turbine is used as the gas turbine.
[0141] Differences from the above-described embodiments will be specifically described below. The gas turbine device 100 in this embodiment is a two-shaft gas turbine in which the gas generator and the rotating shaft of the power turbine are separated. This two-shaft gas turbine has a higher degree of freedom of operation than a one-shaft gas turbine, and can improve part load performance. In the case of driving a generator that is a load of a gas turbine, the generator is generally operated at a rate...
