Abstract:
1. A turbine generator system comprising: a turbine power generation unit including a generator and a turbine configured to drive the generator; a working medium including a lubricant, the working medium causing the turbine power generation unit to operate; an evaporator configured to evaporate the working medium by heat exchange with a heat source and to supply the evaporated working medium to the turbine power generation unit; a condenser configured to liquefy the working medium that has flowed through the turbine power generation unit; a medium feeding pump configured to raise a pressure of the liquefied working medium and to feed the working medium to the evaporator; a circulating pump configured to take out the working medium from a lower portion of the evaporator and to inject the working medium into an inside of the evaporator through an injection port provided at an upper portion of the evaporator; and a feeding passage branched at an outlet of the circulating pump and configured to supply the working medium in a liquid phase extracted from the evaporator to a constituent in the turbine power generation unit, the constituent being lubricated by the working medium.
