Abstract
A nozzle assembly comprises a first-fuel-inlet tube, a second-fuel-inlet tube, and a plate stack. The nozzle-plate stack (100) defines a central circuit, corner air circuits, a first fuel circuit and a second fuel circuit. The fuel circuits include a swirl chamber in which the fuel is swirled prior to being merged with the central circuit. The corner air circuits merge with the central circuit downstream of the fuel circuits' merge and provide an additional swirling component to further shape the fuel-air stream prior to ignition.
