本発明は反動式二相流タービン装置に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reaction type two-phase flow turbine system.
高温高圧の熱水または高圧二相流体は、二相流

伝達される。 It is already known that high-temperature, high-pressure hot water or high-pressure two-phase fluid expands in a two-phase flow nozzle and becomes a high-speed two-phase flow, and that its speed is mainly determined by the enthalpy drop at the nozzle inlet and outlet. In addition, as is known from the invention related to a reaction type two-phase flow turbine in Japanese Patent Application Laid-Open No. 56-154102, the high-speed two-phase flow coming out of the two-phase flow nozzle is blown onto a rotating separation drum, and the high-speed two-phase flow is The kinetic energy of the flow is transmitted as rotational motion power to the rotating separation drum.

れる。 In this case, the rotating separation drum is rotating at high speed due to this kinetic energy, the high-speed two-phase flow coming out of the two-phase flow nozzle is centrifugally separated, the hot water creates a liquid level on the rotating separation drum, and the two-phase flow is This prevents direct contact with the drum and transmits power, while the separated steam is centrifugally separated, discharged from the two-phase flow turbine, and introduced into a separate steam turbine or the like.
更に、高速回転する回転分離ドラムの液面の熱
水は反動水車を経て遠止力により回転分離ドラム

反動力がこの二相流タービンの軸動力となる。 Furthermore, the hot water on the liquid surface of the rotating separation drum that rotates at high speed is discharged outside the rotating separation drum by a remote force through a reaction turbine, and the reaction force that releases the hot water from the reaction turbine is applied to the shaft of the two-phase flow turbine. It becomes the driving force.

る。 Generally, hot water or high-temperature, high-pressure two-phase fluid is expanded in a two-phase flow nozzle, and the rotationally separated steam is converted into power in a steam turbine, but at this time, rather than expanding in one stage from high pressure to low pressure, it is expanded in multiple stages. It is known that the overall efficiency of the two-phase flow turbine and the steam turbine is improved when this is done, and this is mainly due to the fact that the amount of evaporation of hot water increases in the case of multiple stages.
そこで、二相流タービンを多段にすることが総
合効率上重要になる。 Therefore, it is important for overall efficiency to have a multi-stage two-phase flow turbine.
従つて、従来方式においては複数の二相流ター

を提供することにある。 On the other hand, conventional reaction type two-phase flow turbines were all single-stage type, but in the present invention, the hot water discharged from the high-pressure stage reaction turbine is further expanded in a low-pressure two-phase flow nozzle. By installing the rotating separation drum on the same disk on the radius corresponding to the two-phase flow velocity ratio at the outlet, the angular velocity component of the two-phase flow velocity at the outlet of the multistage two-phase flow nozzle on the rotating separation surface can be adjusted. This was done with a focus on the fact that they can be made the same, and its purpose is to provide a reaction type two-phase flow turbine device that can effectively utilize enthalpy and is inexpensive in terms of cost.
