Embodiment Construction

[0012] FIG. 1 is a schematic diagram of an embodiment of a gas turbine system 100 . System 100 includes compressor 102 , combustor 104 , turbine 106 , shaft 108 , and fuel nozzles 110 . In one embodiment, system 100 may include a plurality of compressors 102 , combustors 104 , turbines 106 , shafts 108 , and fuel nozzles 110 . Compressor 102 and turbine 106 are coupled by shaft 108 . The shaft 108 may be a single shaft, or multiple shaft segments coupled together to form the shaft 108 .

[0013] In one aspect, combustor 104 operates the engine using liquid fuel and / or gaseous fuel, such as natural gas or hydrogen-rich syngas. For example, fuel nozzles 110 are in fluid communication with an air supply and a fuel supply 112 . Fuel nozzles 110 generate an air-fuel mixture and discharge the air-fuel mixture into combustor 104 , causing combustion of the heated pressurized gas. Combustor 104 directs hot pressurized exhaust gas through a transition piece into a turbine nozzle (o...

Abstract

The invention relates to a turbine assembly and a method for reducing a fluid flow between turbine components. According to one aspect of the invention, the turbine assembly includes a stator and a rotor adjacent to the stator. The turbine assembly also includes a passage formed in a member coupled to the rotor to form a fluid curtain between the rotor and stator, wherein the fluid curtain reduces a flow between the stator and rotor.

Description

technical field [0001] The subject matter disclosed herein relates to turbines. More specifically, the subject matter relates to reducing fluid flow between components of a turbine. Background technique [0002] In a gas turbine, the combustor converts the chemical energy of the fuel or air-fuel mixture into thermal energy. Thermal energy is transferred by a fluid (usually compressed air from a compressor) to a turbine where it is converted into mechanical energy. In some turbine embodiments, leakage of fluid between components into the compressed hot air reduces the power output of the turbine and reduces efficiency. Leakage of fluid may be caused by thermal expansion of certain components and relative motion between components during operation of the gas turbine. Therefore, reducing fluid leakage between components can improve turbine efficiency and performance. Contents of the invention [0003] According to one aspect of the invention, a turbine assembly includes a...
