ABSTRACT:
Combustion apparatus for a gas turbine engine includes two separate combustion zones; one having a first air flow thereto defined by a plurality of holes in combustion apparatus liner; the second zone has air flow thereto through a second plurality of holes in the combustion apparatus liner. Parallel fuel injectors supply fuel into the respective zones and include a wide angle fuel flow nozzle that supplies fuel to the pilot zone of combustion and a narrow cone fuel injector that directs fuel through the pilot zone without combustion and into a downstream main combustion region where the fuel is then burned with air flow though the second plurality of holes to produce a staged combustion of air fuel in the combustion apparatus to achieve high combustion efficiency over a broad ange of fuel/air ratios as well as more uniform combustor outlet temperatures and low smoke output.
