NOVELTY - The can annular combustor has circumferentially spaced can liners which are cylindrical in shape and enclosed between two cylindrical liners (2,3). Each can (1) has tangentially pointing and circumferentially spaced fuel air nozzles that share a common plane that is normal to the can centerline. All liners are made of high temperature alloys or a ceramic material.    USE - Can annular combustor for gas turbine used in e.g. ground based power generation, land or sea based vehicle, military or commercial aircraft.    ADVANTAGE - The combustor has an improved design that is capable of operating in a normal fashion while minimizing the pollutant emissions that are a result of combustion of a fuel and air mixture while addressing other issues faced by such devices. Staging the fuel and air nozzles to have upstream nozzles inject mainly fuel and another set of nozzles downstream which inject mainly air enhances the mixing of the combustion reactants and creates a specific oxygen concentration in the combustion region that greatly reduces the production of nitrogen oxide. There is no attached/anchored flame, but rather a region in the can near the front wall where diffusion combustion occurs. The separate fuel and air nozzles suggest that air that is injected downstream and propagations upstream will be diluted, thus reducing the oxygen concentration the flame sees and reducing peak flame temperatures making the device capable of reducing emissions. The introduction of compressor discharge air downstream of the combustion region allows for any carbon oxide produced during combustion to be burned/consumed before entering the first stage turbine. The combustor will improve gas turbine emission levels, thus reducing the need for emission control devices as well as minimize the environmental impact of such devices. The tangentially firing fuel and fuel-air nozzles directs any initial flame fronts to the adjacent burner nozzles in each can, greatly enhancing the ignition process of the combustor.
