More than degree.As this barring condition, can include and for example obtain from the detected value of temperature sensor 32 and pressure transducer 34
The degree of superheat of the working media obtaining is in determined temperature with first-class.Additionally, the temperature of working media now becomes than aforesaid
Fiducial temperature lower temperature.
Here, explanation is according to the motion of the electricity generation system of first embodiment.In usual operating, stop valve 21 quilt
Open, on the other hand, the switch valve 23b of bypass 23a and cooling valve 25b are closed.
If circulating pump 8 is driven, the working media of the liquid sent out from circulating pump 8 is to the working media of heater 10
Stream 10a flows into.This working media is evaporated by the heat source medium heating of circulation in heat source medium stream 10b.Using heating
Device 10 and evaporate working media be imported into decompressor 14.Working media is imported in decompressor 14, thus decompressor 14 is revolved
Turn and drive, driven and generated electricity by this electromotor 16.The working media expanding in decompressor 14 is discharged to recycle stream
Road 4.The gasiform working media ejecting from decompressor 14 is imported into the flow of operating medium 6a of condenser 6.In condenser 6
In, working media is condensed by the cooling medium cooling of circulation in cooling medium stream 6b.The working media of this liquid is following
Circulate in circulation road 4 and sucked by circulating pump 8.In circulation stream 4, repeat such circulation and carry out sending out in electromotor 16
Electricity.
When TRT 1 operates, the rotating speed of circulating pump 8 is controlled to make the mistake of the working media in heater 10 downstream
Temperature falls in set scope.That is, as shown in Fig. 2 detected value P1, T1 quilt of pressure transducer 34 and temperature sensor 32
It is input to controller 30（Step ST1）, pump controlling organization 30a based on this detected value P1, T1 be circulated pump 8 control so that
In the range of the degree of superheat of working media falls into and presets（Step ST2）.
Then, cool down controlling organization 30b detected value P1, T1 based on pressure transducer 34 and temperature sensor 32, really
Recognize whether working media is in superheat state and judges the detected value T1 of temperature sensor 32 whether as benchmark set in advance
Temperature（Higher limit）Below Tr（Step ST3, ST4）.Additionally, superheat state refers to and the working media under detected pressure value P1
Saturation temperature compares the higher state of temperature detection value T1.Then, when working media is in superheat state, judging temperature biography
In the case that the detected value T1 of sensor 32 exceedes fiducial temperature Tr, open cooling valve 25b（Step ST5）.Such situation example
As import the temperature of heat source medium of heater 10 sharp rise thus with the rotating speed of circulating pump 8 rise can not to corresponding when
Occur.
If opening cooling valve 25b, it is split to cold from the spue part of the working media of the liquid come of circulating pump 8
But use path 25a.Then, flow through and be in superheat state in the working media of liquid of cooling path 25a and circulation stream 4
Working media interflow.Therefore, flow out from heater 10 and circulate circulation stream 4 towards stop valve 21 and decompressor 14
Gasiform working media by interflow liquid working media gasification and be cooled.From cooling with path 25a to circulation
The working media of the liquid that the part of ratio heater 10 in stream 4 side farther downstream imports only will flow out from heater 10
The temperature of the gasiform working media in circulation stream 4 reduces, i.e. take away sensible heat, therefore with the situation taking away latent heat
Compare heat that need not be bigger.Therefore, the working media of above-mentioned liquid is on a small quantity.
Additionally, cooling path 25a is made up of the pipe arrangement thinner with circulation stream 4 phase diameter group, therefore prevent volume
Working media is in cooling situation about circulating in path 25a.Therefore, the working media of heater 10 is flowed into by circulating stream 4
Amount will not be reduced to affect heater 10 in accumulation working media amount degree, almost do not have the degree of superheat to go up further yet
Situation about rising.
In the state of cooling valve 25b is opened, judge the detection from temperature sensor 32 and pressure transducer 34
Whether degree of superheat SH that value T1, P1 calculates is in the benchmark degree of superheat（Lower limit）More than SHr（Step ST6）.Then, if overheated
SH is lower than benchmark degree of superheat SHr for degree, then valve 25b is used in locking cooling（Step ST7）.Thus, it is back to and spue from circulating pump 8
Working media will not to cooling path 25a shunting but be imported into the usual operating of heater 10.
As described above, in the first embodiment party, the temperature at the downstream of heater 10 is by cooling body 25
The working media cooling being in superheat state more than predetermined value.Accordingly, it is capable to suppression is flowed out from heater 10 and is flowed into
The temperature of the working media of decompressor 14.Therefore, even if when the temperature of heat source medium sharp rises etc., also can effectively press down
The intensification of working media processed.Therefore, there is no need to from heater 10 to the liner of flange present in the path of decompressor 14
Constitute Deng the material with having thermostability, in addition, improving also without by the rank of insulant used in electromotor 16
Etc. countermeasure.
In addition, in the first embodiment, be configured to cooling body 25 make from the downstream of pump and heater 10 upstream
The working media that side is diverted collaborates in circulation stream 4 thus cooling work medium.Accordingly, it is capable to suppression is as TRT 1
Complex structure, in addition, can more effectively cooling work medium.
In addition, in the first embodiment, the working media in the downstream of heater 10 maintains more than saturation temperature, because
This can prevent the working media of liquid to be imported into decompressor 14.Accordingly, it is capable to prevent decrease of power generation.
In addition, first embodiment carries out the cooling of the working media of superheat state using the heat of gasification of working media, because
This can be more effectively carried out the cooling of working media.That is, with a small amount of cooling medium, the working media of superheat state can be cooled down.
Particularly, the working media downstream from circulating pump 8 being diverted uses as cooling medium, therefore from circulating pump 8 to
The amount of the working media of heater 10 conveying only slightly reduces.Therefore, that is, order divides from the working media being spued by circulating pump 8
Stream, also has little to no effect.

Machine（Omit diagram）Pressurized air circulation stream constitute situation.Heat exchanger 25f is arranged at the heating in closed circuit 4
The downstream of device 10.The steaming outside figure that the cooling flowing path 25e of heat exchanger 25f can also be arranged from the ship carrying electromotor
Vapour equipment imports residual steam.When electromotor is by high loaded process, such as 150 DEG C about above pressurized airs are imported into and add
Hot device 10.Therefore, in the flow of operating medium 10a of heater 10, the working media of circulation is heated to 150 DEG C about of temperature
Degree.In this case, by the cooling valve of the cooling path 25a by being arranged at cooling body 25（The mechanism of decompressor）25b's
Aperture reduces, and thermal medium is reduced pressure, thus reducing the temperature of thermal medium.Thus, can be by the working media stream in heat exchanger 25f
The working media cooling of the superheat state of circulation in the 25d of road.Additionally, in time of engine low load operation, sometimes in heater 10
Middle working media is not sufficiently heated, and therefore, now heat exchanger 25f can also be heated to superheat state as by working media
Superheater and function.
As shown in figure 4, in the electricity generation system according to this embodiment, based on pressure transducer 34 and temperature sensor
32 detected value P1, T1, confirms whether working media is in superheat state（Step ST3）.Then, be in working media overheated
During state, in the case that the detected value T1 judging temperature sensor 32 exceedes fiducial temperature Tr（Step ST4）, cool down control machine
Structure 30b enters to be about to the control of cooling valve 25b throttling（Step ST11）.Thus, thermal medium is depressurized, in heat exchanger 25f
Working media is cooled（The sensible heat of working media is removed）.
Carried out in the state of throttle with valve 25b in cooling, judge by temperature sensor 32 and pressure transducer 34
Degree of superheat SH that calculates of detected value T1, P1 whether be in the benchmark degree of superheat（Lower limit）More than SHr（Step ST6）.Then,
If degree of superheat SH becomes lower than benchmark degree of superheat SHr, release the control of throttling cooling valve 25b（Step ST7）.Now,
In the case that working media is not sufficiently heated, can auxiliarily heating work medium, degree of superheat SH of working media can be made
Rise.
