METHOD OF COMBUSTION WITH LOW ACOUSTICS

摘要

A method of reducing pressure fluctuations in the combustor of a gas turbine engine resulting from the combustion of fuel and air therein comprises combustin g a fuel/air mixture in a combustor downstream of the exit plane of a fuel nozzle as sembly such that such recirculation zones generated by the fuel nozzle assembly are in spaced relation to the exit plane and the combustion products are isolated from the fue l and air in the mixing zone at all operating conditions of the engine.
