Abstract
A method of operating a gas turbine combustor includes: selectively directing fuel and a first air supply through a fuel nozzle assembly in a head end section to produce a first fuel/air mixture, which is ignited within a liner to produce combustion gases; selectively directing a second fuel/air mixture through the liner from at least one first injector disposed at a first axial location; selectively directing a third fuel/air mixture through the liner from at least one second injector disposed at a downstream, second axial location. Each of the fuel nozzle assembly, the first injector(s), and the second injector(s) receives only a respective air supply from a compressor discharge plenum. The second injector(s) receive a respective air supply that is greater than each of the respective air supplies of the fuel nozzle assembly and the first injector(s).
