ANNULAR INJECTOR ASSEMBLY AND METHODS OF ASSEMBLING THE SAME

摘要

An annular injector is described. The injector includes a first bayonet assembly and a second bayonet assembly each including a terminal end and a tip end. The second bayonet assembly is configured to be concentrically coupled at least partially about the first bayonet assembly. An outer diameter of the first bayonet assembly and an inner diameter of the second bayonet assembly vary at the tip end to define a first substantially annular nozzle. The first bayonet assembly includes a maximum outer diameter that is greater than a minimum inner diameter of the second bayonet assembly and at least a portion of at least one of the first bayonet assembly and the second bayonet assembly extends from the tip end to the terminal end. The injector includes a third bayonet assembly configured to be concentrically coupled at least partially about the second bayonet assembly to define a second substantially annular nozzle.
