Abstract:
1. A gas turbine power plant comprising a compressor for compressing air, a combustor for mixing the compressed air with fuel so as to burn the fuel, a gas turbine adapted to be driven by combustion gas produced from the combustor, a generator having, in a generator housing, a stator winding and a rotor driven by the gas turbine and journalled by bearings, and a cooling water circulating means for cooling the generator, wherein water lubrication bearings are arranged in the generator housing, and are used as the bearings in the generator, and cooling water is fed into the water lubrication bearings from the cooling water circulating means by way of a heat radiator, and a blower is provided for feeding outside air as sealing air between end faces of the stator winding and the water lubrication bearings in the generator housing so as to allow the sealing air to define a seal surface against water scattering from the water lubrication bearings.
