Abstract
A multi-functional fuel nozzle () for a combustion turbine engine is provided. An annular fuel-injecting lance () may include a first fluid circuit () and a second fluid circuit (). One of the first and second fluid circuits during a liquid fuel operating mode of the combustion turbine engine may convey a liquid fuel. The other of the first and second fluid circuits may convey a selectable non-fuel fluid. An atomizer () is disposed at the downstream end of the lance. The atomizer may have a first ejection orifice () responsive to the first fluid circuit to form a first atomized ejection cone (), and a second ejection orifice () responsive to the second fluid circuit to form a second atomized ejection cone (). The first and second ejection cones () formed with the atomizer may be concentric cones that intersect with one another over a predefined angular range.
