Abstract
Systems for thermally regulating portions of a steam turbine are disclosed. In one embodiment, a thermal control system for a rotor bearing support includes: a housing fluidly connected to an inlet and adapted to substantially enclose the rotor bearing support, the housing defining a first annular cavity adapted to receive a fluid from the inlet; and an outlet fluidly connected to the housing, the outlet adapted to receive the fluid from the annular cavity.

A thermal control system for a rotor bearing support, the thermal control system comprising:
- a housing fluidly connected to an inlet and adapted to substantially enclose the rotor bearing support, the housing defining a first annular cavity adapted to receive a fluid from the inlet;
- and
- an outlet fluidly connected to the housing, the outlet adapted to receive the fluid from the annular cavity.
A steam turbine comprising:
- a stator;
- a rotor enclosed within the stator;
- a set of rotor bearings connected to the rotor;
- a first rotor bearing support connected to a first portion of the set of rotor bearings;
- a second rotor bearing support connected to a second portion of the set of rotor bearings;
- and
- a thermal control system connected to the first rotor bearing support, the thermal control system comprising:
- an inlet;
- a housing fluidly connected to the inlet and adapted to substantially enclose the first rotor bearing support, the housing defining a first annular cavity adapted to receive a fluid from the inlet;
- and
- an outlet fluidly connected to the housing, the outlet adapted to receive the fluid from the annular cavity.
A power generation system comprising:
- a generator;
- a steam turbine operatively connected to the generator;
- a rotor disposed within the steam turbine;
- a set of rotor bearings connected to the rotor;
- a first rotor bearing support connected to a first portion of the set of rotor bearings;
