Abstract
Provided is a gas turbine power plant in which a rotor of a generator is journalled by water lubrication bearings into which a part of cooling water for cooling the generator 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.
Claims
exact text as granted — not AI-modified1 . A generator comprising, in a generator housing, a stator and a rotor journalled by bearings, characterized by water lubrication bearings arranged in the generator housing and used as the bearings in the generator, and means for feeding air between the stator and the water bearings in the generator housing.
