  • Publication number: 20090104028
    Abstract: An apparatus for distributing a fluid in a gas flow path inside a turbomachine, comprising: a device for introducing the fluid into the gas flow path; and wherein the device is positioned within the gas flow path. A method for installing an apparatus that will distribute a fluid in a gas flow path inside a turbomachine, the method comprising: machining a casing groove along an inner surface of a casing; machining at least one port into the casing that is in fluid communication with the casing groove; machining an internal cavity in at least one stator blade that is in fluid communication with the casing groove; machining at least one orifice, that is in fluid communication with the internal cavity, on an orifice surface of the stator blade; and coupling a fluid supply to the at least one port.

  • Patent number: 6192689
    Abstract: An optimized combustor cooperating with a compressor in driving a gas turbine comprises a cylindrical outer combustor wall having an upstream fuel entry region and a downstream turbine entry region. An array of mixing holes are disposed about the periphery of the outer combustor wall adjacent to the fuel entry region so as to lower Nox production therein. An array of dilution holes are medially disposed within the outer combustor wall to provide an entry for dilution air to the combustor.
