Multiple venturi tube gas fuel injector for a combustor

摘要

A gas fuel injector (24) includes a first header plate (36); a second header plate (38) spaced downstream from the upstream header plate (36); and a plurality of venturi tubes (34) arranged in rows and sealably secured to the first and second header plates (38). Each of the venturi tubes includes an inlet section (40), a throat section (42) and an exit (46). The exit (46) is shaped into a pattern that reduces space between each of the venturi tubes at the exit (46) of each of the plurality of venturi tubes (34).
