COMBUSTOR NOZZLE AND METHOD FOR SUPPLYING FUEL TO A COMBUSTOR

摘要

A combustor nozzle includes a fuel supply in fluid communication with a fuel passage that terminates at a fuel outlet. An oxidant supply is in fluid communication with an oxidant passage radially displaced from the fuel passage and that terminates at an oxidant outlet radially displaced from the fuel outlet. A diluent passage radially displaced from the fuel passage and the oxidant passage terminates at a diluent outlet disposed between the fuel outlet and the oxidant outlet. A method for supplying fuel to a combustor includes flowing the fuel through a fuel outlet and flowing an oxidant through an oxidant outlet radially displaced from the fuel outlet. The method further includes flowing a diluent through a diluent outlet radially disposed between the fuel outlet and the oxidant outlet.
