A fuel nozzle and a method for operating a combustor are disclosed. The method includes flowing a fuel and an oxidizer through a fuel nozzle (40), the fuel nozzle comprising an inner tube (52), an intermediate tube (54), and an outer tube (56) each configured for flowing one of the fuel or the oxidizer therethrough. At least one of the inner tube (52), the intermediate tube (54), or the outer tube (56) includes a plurality of swirler vanes (106). The method further includes imparting a swirl to the fuel and the oxidizer in the fuel nozzle, and exhausting the fuel and the oxidizer from the fuel nozzle into a combustion zone (24). |
