Abstract
A combustor nozzle includes a first and second liquid fuel passages that terminate at first and second fuel ports. A first diluent passage terminates at a first diluent outlet radially surrounding the second fuel ports. A second diluent passage terminates at a second diluent outlet between the first diluent outlet and the second fuel ports. A third diluent passage surrounds at least a portion of the first and second diluent passages. A method for supplying fuel to a combustor includes flowing a liquid fuel through a first fuel passage and flowing an emulsified liquid fuel through a second fuel passage. The method further includes flowing a first diluent through a shroud surrounding the second fuel passage to a first diluent passage surrounding at least a portion of the second fuel passage and flowing a second diluent through a second diluent passage radially disposed between the first diluent passage and the second fuel passage.
