Abstract:
A combustor for producing a hot gas by burning a fuel in air, said combustor having:a) a combustion zone;b) a first annular passage for mixing fuel and air, said first annular passage in flow communication with said combustion zone;c) a first manifold for introducing a liquid fuel into said first annular passage so as to circumferentially distribute said liquid fuel around said first passage; andd) a second manifold for introducing a gaseous fuel into said first annular passage so as to circumferentially distribute said gaseous fuel around said first passage, said first and second manifolds joined together to form an integral manifold assembly;e) wherein said combustor defines an axial direction, and wherein said first annular passage has a flow area axially projected onto a plane perpendicular to said axial direction, and wherein said second manifold has an area axially projected onto said flow area projected area, and wherein the area axially projected onto said flow area by said first and second manifolds as joined into said integral manifold assembly is substantially the same as said projected area of said second manifold.
