、クローズドサイクルの作動ガスとして重要な要因であ
る。As a working gas for the cycle, helium has large specific heat and specific enthalpy, and if there is a sufficient heating source, it is a gas that can easily extract work through a turbine. However, because the molecular weight is small, it does not put a load on the compressor and the cycle cannot be completed. Therefore, this helium is mixed with xenon, which has a large molecular weight, and a compressor performs sufficient compression to form a cycle. The fact that both helium and xenon are inert gases that are difficult to react with is also an important factor as working gases for closed cycles.
上述のとおり、ヘリウムとキセノンは各々異なる性質を

トロールしたりするために、混合比のコントロールが不
可欠である。As mentioned above, since helium and xenon each have different properties, their properties as a mixed gas are affected by the mixing ratio. If there is a large amount of helium, it will be thermally advantageous, but it will not be able to be compressed completely, and conversely, the amount of work that can be extracted will decrease. Therefore, in order to obtain a constant output or control the output, it is essential to control the mixing ratio.

続的に混合比を決定することは、可能であった。[Problems to be Solved by the Invention] In order to adjust the mixing ratio of working gas in a gas turbine cycle, it is first necessary to measure the mixing ratio. Conventionally, it has been possible to determine the mixing ratio discontinuously by measuring the specific gravity of a sample of mixed gas.

We propose a method for adjusting the mixture ratio of turbine working gas, which involves measuring the wavelength characteristics of absorption and scattering by irradiating it, comparing it with the preset wavelength characteristics, and mixing in the missing gas until the two match. It is something to do.

In addition, the working gas supply valve can be opened and closed based on the measurement results, and the working gas mixture ratio can always be maintained appropriately.

■ 指向性が強いため、内部に手が届かない場所でも測
定可能。In this embodiment, laser light is used to measure the mixing ratio of working gases. Generally, when light hits a substance, some of it is transmitted, and the rest is absorbed or scattered. Light absorption and scattering are phenomena that occur due to the interaction between light and substances, and by measuring the wavelength characteristics of the intensity of light absorption and scattering, the properties of the irradiated substance can be determined. As a bright line light source for measuring the wavelength characteristics, ■ Strong directivity allows measurements even in places where the interior is hard to reach.
■ 位相がそろった光である。■ The light is in phase.
■ 輝度が高く、微少量の物質でも測定可能。■ High brightness and can measure even minute amounts of substances.

を補充する。The emission line caused by the laser beam appears more clearly as the pressure increases, so in this example, we take advantage of this fact and place the laser oscillator a and the light receiving part ( Diffraction grating, light receiving sensor, etc.) θJ is installed. Then, the emission lines generated when the mixed gas is irradiated with laser light are divided into multiple frequency bands using a diffraction grating, and the pattern of signal intensity in each frequency band is preliminarily set during the ground test and stored in memory 09. Compare it with the pattern information of the appropriate mixture ratio that you have prepared, and set the valve opening degree and timing as a signal/Ji.
