  • Steam turbine
    Patent number: 6305901
    Abstract: A steam turbine has a high-pressure turbine section and a medium-pressure turbine section fluidically connected to the high-pressure turbine section. The high-pressure turbine section is a chamber configuration and the medium-pressure turbine section is a drum configuration. Alternatively, the high-pressure turbine section is a drum configuration and the medium-pressure turbine section is a chamber configuration. Alternatively, or additionally, the high-pressure turbine section is a double-flow configuration and the medium-pressure turbine section is a double-flow configuration.
