Gas turbine power plant

摘要

Provided is a gas turbine power plant in which a rotor (7) of a generator (3) is journalled by water lubrication bearings (10A, 10B) into which a part of cooling water for cooling the generator (3) is fed. Since the lubrication water has a viscosity lower than that of lubrication oil, it is possible to provide a gas turbine power plant with less energy loss resulting in lower power consumption for accessories, and in high power generation efficiency.
