20090025389 | Turbine Systems and Methods for Using Internal Leakage Flow for Cooling - A cooling system for a turbine with a first section and a second section. The first section may include a first line for diverting a first flow with a first temperature from the first section, a second line for diverting a second flow with a second temperature less than the first temperature from the first section, and a merged line for directing a merged flow of the first flow and the second flow to the second section. | 01-29-2009 |
20100000216 | Steam turbine overload valve and related method - A steam turbine operating system includes at least a high pressure turbine section and a low pressure section; one or more control valves arranged to admit steam from a boiler to the high pressure turbine section; a condenser arranged to receive steam exhausted from the low pressure section and to convert the steam to a liquid; a top heater arranged to receive liquid from the condenser and to heat the liquid via heat exchange with steam from the high pressure section, and to return the heated liquid to the boiler; and an overload bypass valve arranged to supply steam bypassed around the one or more control valves directly to the top heater. | 01-07-2010 |

20100021283 | SYSTEM AND METHOD FOR PROVIDING SUPERCRITICAL COOLING STEAM INTO A WHEELSPACE OF A TURBINE - A system for cooling a high pressure section of a turbomachine includes a conduit configured to carry cooling steam from a boiler to a space upstream of a first stage nozzle of the turobmachine. The conduit extends through a housing of the turbomachine and a nozzle diaphragm of the first stage nozzle. The system further includes a control valve in the conduit configured to regulate the flow of cooling steam. A turbomachine includes a housing; a turbine shaft rotatably supported in the housing; and a plurality of turbine stages located along the turbine shaft and contained within the housing. Each turbine stage includes a diaphragm attached to the housing. The diaphragm comprises a plurality of nozzles. A hole is provided in the diaphragm upstream of a first stage of the plurality of stages for the introduction of cooling steam. A method of cooling a high pressure section of a turbomachine includes introducing cooling steam into the turbomachine through the at least one hole. | 01-28-2010 |
20100251716 | COOLED EXHAUST HOOD PLATES FOR REDUCED EXHAUST LOSS - Cooled exhaust hood plates are provided in areas of high velocity steam flow within an exhaust steam flow of a steam turbine. Coolant is directed within double walled exhaust hood plates to cool plate surfaces adjacent to the high velocity exhaust steam flow. The cooled exhaust hood plates cool and condense the exhaust steam in proximity. Condensation will occur in low velocity area near the exhaust hood plate to reduce the boundary layer and improve the flow through the hood, improving overall turbine performance. | 10-07-2010 |
20110162341 | CLUTCHED TURBINE WHEELS - Solutions for clutching turbine wheels are disclosed. In one embodiment, an apparatus includes: a turbine rotor shaft; a plurality of turbine wheels affixed to the turbine rotor shaft; an independent turbine wheel engagably attached to the turbine rotor shaft; and a clutch operably connected to the turbine rotor shaft, the clutch configured to couple and decouple the independent turbine wheel from the turbine rotor shaft. | 07-07-2011 |

20090217673 | APPARATUS AND METHOD FOR DOUBLE FLOW TURBINE TUB REGION COOLING - Disclosed is a steam turbine including a turbine rotor, a generator end having a generator end first stage with a first reaction, and a turbine end having a turbine end first stage with a second reaction not equal to the first reaction. The steam turbine includes a tub section disposed between the generator end and the turbine end, the turbine rotor and the tub section defining an annulus therebetween. A difference between the first reaction and second reaction is capable of urging a steam flow through the annulus for reducing a temperature of the turbine rotor. A method of cooling the turbine rotor is also disclosed. | 09-03-2009 |
20100038917 | STEAM TURBINE CLUTCH AND METHOD FOR DISENGAGEMENT OF STEAM TURBINE FROM GENERATOR - A power generation system including: at least one elevated steam turbine receiving input steam at an elevated pressure and exhausting steam as low pressure steam; a low pressure steam turbine receiving low pressure steam exhausted from the elevated steam turbine, and a drive shaft for the low pressure steam turbine connected to a clutch which is reasonably coupled to a power generator, wherein the clutch has a first position in which power from the low pressure steam turbine is applied to the power generator and a second position in which power from the low pressure steam turbine is not applied to the generator. | 02-18-2010 |
20100178156 | STEAM TURBINE HAVING EXHAUST ENTHALPIC CONDITION CONTROL AND RELATED METHOD - A steam turbine includes a casing including a steam inlet and an exhaust, the casing enclosing operative structure of the steam turbine; a valve controlling introduction of a steam flow at a location of the steam turbine to impact an enthalpic condition of steam exiting the exhaust; and a controller controlling operation of the valve to attain a desired enthalpic condition of steam exiting the exhaust. Controlling operation of the valve allows for attainment of a desired enthalpic condition of the steam exiting the exhaust for use in another industrial process without having to modify the steam turbine structure. | 07-15-2010 |
