<p>A support structure for a low NOx industrial gas turbine engine fuel nozzle includes a pressure vessel (38) which forms an interior cavity (50) such that the exterior of the pressure vessel is exposed to the high pressure and temperature of the compressor outlet while the interior cavity of the pressure vessel is exposed to ambient conditions. The fuel lines (46, 44) to the nozzle run through the interior cavity of the pressure vessel, isolated from the high temperatures and pressures at the compressor outlet. The pressure vessel housing and the ambient air within the housing acts as natural insulators which prevent the fuel lines from becoming too hot and choking. The support structure (60) also facilitates maintenance of the combustor section of the engine since the low NOx fuel nozzle and the annular combustor assembly of the engine are easily accessible for maintenance.</p> |
