Abstract
Aspects of the present disclosure include turbomachines designed and configured for high temperature and pressure operation and increased power level output that minimize pressure vessel design requirements, and increase dry gas seal reliability. In some examples, a first radial bearing is located in a high temperature and/or pressure region of the turbomachine between a rotor of the machine and a dry gas seal while other bearings are located outside of the high pressure region.
Claims20
A turbomachine, comprising:
- a shaft;
- a rotor, a first bearing, at least one second bearing, and a dry gas seal, each of the rotor, first bearing, at least one second bearing and dry gas seal being operably coupled to the shaft;
- wherein the dry gas seal defines a pressure boundary between a high pressure region and a low pressure region of the turbomachine, the first bearing located between the rotor and the dry gas seal in the high pressure region and the at least one second bearing located in the low pressure region.
A turbomachine, comprising:
- a shaft;
- a rotor coupled to the shaft at an interface;
- a gas seal coupled to the shaft;
- and
- a coolant flow path configured to route a cooling fluid through the interface to cool the rotor and shaft.
