摘要:
A system for deicing a wind turbine blade includes an electrically powered active plasma actuator (10) applied to a desired portion of a wind turbine blade (30). The activated plasma actuator (10) energizes the air (22,26) in the vicinity of the plasma actuator (10) to increase the surface temperature of the wind turbine blade (30) in the vicinity of the plasma actuator (10) sufficiently to reduce or eliminate the collection of ice on a desired portion of the wind turbine blade (30).

A system 50 and a method of generating energy in a power plant using a turbine 64 are provided. The system 50 includes an air separation unit 12 providing an oxygen output; a plasma generator 54 that is capable of generating plasma 60; and a combustor 14 configured to receive oxygen and to combust a fuel stream 58 in the presence of the plasma 60, so as to maintain a stable flame, generating an exhaust gas 62. The system 50 can further include a water condensation system 16, fluidly-coupled to the combustor 14, that is capable of producing a high-content carbon dioxide stream 70 that is substantially free of oxygen. The method of generating energy in a power plant includes the steps of operating an air separation unit 12 to separate oxygen from air, combusting a fuel stream 58 in a combustor 14 in the presence of oxygen, and generating an exhaust gas 62 from the combustion. The exhaust gas 62 can be used in a turbine 64 to generate electricity. A plasma 60 is generated inside the combustor 14, and a stable flame is maintained in the combustor 14.

摘要:
A fuel nozzle assembly (118) for use with a turbine engine includes at least one fuel conduit (212/216) coupled to at least one fuel source. The fuel nozzle assembly also includes at least one swirler (222) that includes at least one wall (230) having a porous portion (234/236). The at least one wall is coupled to the at least one fuel conduit. The porous portion is formed from a material (300) having a porosity that facilitates fuel flow (246/248) therethrough. At least one fuel flow path is thereby defined through the porous portion of the at least one wall.
