<P>PROBLEM TO BE SOLVED: To provide a new gas turbine that has a fuel system configuration to obtain a peak fuel temperature in a lower range and/or uses a method of staging a fuel. <P>SOLUTION: A nozzle for assemblies and gas turbines is provided. The nozzle exhibits destabilized flame holding characteristics, i.e., the nozzle is unable to stabilize flame up to an equivalence ratio of about 0.65. As a result, flame heat release is delayed resulting in lower peak flame temperatures and correspondingly lower NOx levels. Flame stabilization capability is retained for higher equivalence ratios to support operation of the combustor in other regions of the load range. <P>COPYRIGHT: (C)2012,JPO&INPIT |
