NON-SYMMETRIC ARRANGEMENT OF FUEL NOZZLES IN A COMBUSTOR

摘要

A fuel nozzle arrangement includes an annular combustor (14A - 14D)having four quadrants (Q1 - Q4). Fuel injectors are located in the four quadrants (Q1 - Q4) and each fuel injector has either a first or second type nozzle (40H, 40C) attached to it. The first and second type fuel nozzles (40H, 40C) are located in an array so that at least two of one nozzle type are located together to allow for non-uniform injector spacing with uniform downstream temperatures.
