摘要： A dual mode, dual stage low NOx combustor, includes a primary combustion chamber and a secondary combustion chamber separated by a throat region of reduced diameter. Fuel is input into the primary combustors by an annular array of diffusion type nozzles whereas in accordance with the invention, fuel is input into the secondary combustor by a central combination premix and diffusion nozzle. A premix swirler annulus is located upstream of a plurality of fuel distribution tubes of the combined premix and diffusion nozzle.
