このような冷熱発電設備の運転方法では、次のような欠

中に蓄積される。このようにして、媒体蒸発器では、液
化媒体中の潤滑油濃度が次第に高まる。In order to prevent the vaporized medium from leaking into the atmosphere from the shaft seal of the media turbine, a shaft seal mechanism such as an oil film seal or mechanical seal is generally employed on the shaft of the media turbine that is in contact with the atmosphere. . By adopting such a shaft seal mechanism, it is possible to prevent the vaporized medium from leaking into the atmosphere, but on the other hand, it is unavoidable that a small amount of lubricating oil from the shaft seal mechanism gets mixed into the vaporized medium. Due to problems such as damage to the lubricating oil, a large amount of lubricating oil may temporarily become mixed into the vaporizing medium. Due to its low vapor pressure, this lubricating oil does not evaporate or vaporize even when the liquefied medium is evaporated or vaporized in the medium evaporator, and most of it is accumulated in the liquid medium. In this way, the lubricating oil concentration in the liquefied medium gradually increases in the medium evaporator.
このように媒体蒸発器での液化媒体中の潤滑油濃度が高
まると、液化媒体の沸騰時に泡沫が生じ、その高さは、
潤滑油濃度が高まるに従い高くなる。When the lubricating oil concentration in the liquefied medium in the medium evaporator increases in this way, foam is generated when the liquefied medium boils, and its height is
It increases as the lubricant concentration increases.

媒体タービンを良好に運転できなくなる。なお、このよ
うな事態は、他の低い蒸気圧を有する油が混入した場合
でも生じる。As the boiling surface foam height increases and the foam reaches the demister, the liquefied medium will be entrained in the vaporized medium supplied to the medium turbine.The amount of entrained liquefied medium will be The amount increases as the lubricating oil concentration increases. As a result, vibrations and abnormal noises occur in the medium turbine, making it impossible to operate the medium turbine satisfactorily. Incidentally, such a situation occurs even when other oils having low vapor pressures are mixed in.

必要となり２ンキン媒体費が増大する。Conventionally, when such a situation occurs, it has been dealt with by temporarily stopping the operation and replacing the Rankine medium with a new Rankine medium.As a result, the cold power generation equipment cannot be operated properly and continuously for a long period of time, and A large amount of Rankine media is required, increasing the cost of the Rankine media.
本発明は、上記した従来技術の欠点を解消することで、

への液化媒体の同伴を抑制するようにしたことにある。The feature of the present invention is to reduce the oil concentration in the liquefied medium remaining in the medium evaporator to such a level that the height of the bubbles generated when the liquefied medium boils is smaller than the distance between the liquid level of the liquefied medium and the lower surface of the demister. By adjusting the temperature, entrainment of the liquefied medium into the vaporized medium supplied to the medium turbine can be suppressed without once stopping the operation of the cold power generation equipment.

）の下面との間隙Ｈと泡沫高さとの関係により決まる。The entrainment of the liquefied medium into the vaporized medium supplied from the medium evaporator 12 to the medium turbine 13 via the conduit n is caused by the difference between the liquid level of the liquefied medium in the medium evaporator 13 and the lower surface of the demister, as described above. It is determined by the relationship between the gap H and the foam height.
