It is economical and can greatly help reduce installation space. In addition, two-phase flows consisting of a mixture of steam and hot water, such as geothermal water, contain various dissolved substances and solid substances, which can cause problems such as scale generation and the contamination of solid substances. However, in the power generating apparatus of the present invention, it is possible to solve this problem by specifically using a rotationally separated two-phase flow turbine.
