摘要： A rotor of a turbomachine includes a rotor drum located at a central axis and a plurality of buckets secured to the rotor drum. A rotor shell extends between axially adjacent buckets of the plurality of buckets and is secured to and supported by the plurality of buckets defining a cooling passage between the rotor drum and the rotor shell. A low pressure sink is located at an upstream end of the rotor receptive of a coolant flow through the cooling passage. A method of cooling a rotor of a steam turbine includes locating a rotor shell radially outboard of a rotor drum defining a cooling passage therebetween. A flow of steam is urged from a downstream portion of the steam turbine through the cooling passage toward a low pressure sink located at an upstream end of the steam turbine thereby cooling the rotor.

摘要： Systems and methods for actively controlling the temperature in at least portions of a steam path associated with a steam turbine are disclosed. An active temperature control unit is configured to activate one or more attemperators to maintain temperatures in at least a portion of the steam path below a pre-determined threshold. By maintaining the temperature, those portions of the steam path may use less expensive materials.

摘要： An open cooling circuit for a gas turbine airfoil and associated tip shroud includes a first group of cooling holes internal to the airfoil and extending in a radially outward direction generally along a leading edge of the airfoil; a second group of cooling holes internal to the airfoil and extending in a radially outward direction generally along a trailing edge of the airfoil. A common plenum is formed in the tip shroud in direct communication with the first and second group of cooling holes, but a second plenum may be provided for the second group of radial holes. A plurality of exhaust holes extends from the plenum(s), through the tip shroud and opening along a peripheral edge of the tip shroud.

摘要： A turbine rotor blade comprises a shank portion, a tip portion and an airfoil. The airfoil has a pressure side wall and a suction side wall that are interconnected by a plurality of partition sidewalls, defining an internal cooling passageway within the airfoil. The internal cooling passageway includes at least one radial outflow passageway to direct a cooling medium flow from the shank portion towards the tip portion and at least one radial inflow passageway to direct a cooling medium flow from the tip portion towards the shank portion. A number of mixing ribs are disposed on the partition sidewalls within the radial outflow passageways so as to enhance the thermal mixing of the cooling medium flow, thereby producing improved heat transfer over a broad range of the Buoyancy number.
