Beschreibung
Zusammenfassung:	A jet micro-induced flow reversals combustor is used to reduce NOx emissions. The combustor has a nozzle disposed at the head end of the combustion chamber. The nozzle includes a plurality of jets for injecting a fuel and oxidant mixture stream into the combustion chamber. A combustion liner is disposed within the casing on one side of the nozzle and a plenum chamber is disposed on another side of the nozzle and configured to provide an input of a fuel and oxidant. The nozzle and the combustion liner are sized and shaped to input the fuel and oxidant mixture stream into the combustion liner at a high velocity ratio wherein a jet velocity is greater than a combustion mean velocity within the combustion liner, to increase turbulence within the combustion liner and reduce combustion emissions.
