Abstract
An improved combined cycle plant with a gas turbine, a steam turbine and a generator arranged in tandem on a single shaft system in the order aforementioned, including a single thrust bearing with rigidly coupled rotor members. A thrust bearing for the shaft system is supported in a bearing standard keyed to the foundation on the side of the steam turbine toward the gas turbine to restrain axial movement. The thrust bearing is preferably located in the compressor inlet of the gas turbine. The steam turbine comprises a first casing with the hihg pressure section supported in a bearing standard keyed to the foundation adjacent the thrust bearing. The second casing with the low pressure section is keyed to the foundation at its outlet in the center of the exhaust hood. In a preferred arrangement with a single flow low pressure turbine section, the second casing combines an intermediate pressure turbine section adjacent the generator receiving steam from the reheater. In a modified arrangement with a double flow low pressure section, the intermediate pressure turbine section turbine section is combined with the high pressure turbine section in the first casing.
