METHOD AND APPARATUS TO FACILITATE REDUCING NOx EMISSIONS IN TURBINE ENGINES

摘要

A METHOD AND APPARATUS TO FACILITATE REDUCING NO? EMISSIONS IN TURBINE ENGINES IS PROVIDED. THE METHOD INCLUDES PROVIDING AN ANNULAR SHELL INCLUDING A PLURALITY OF CIRCUMFERENTIALLY EXTENDING PANELS. THE PLURALITY OF CIRCUMFERENTIALLY EXTENDING PANELS INCLUDES A FIRST PANEL (82) POSITIONED AT AN UPSTREAM END OF THE SHELL AND A SECOND PANEL (86) POSITIONED DOWNSTREAM FROM, AND ADJACENT TO, THE FIRST PANEL (82). THE METHOD ALSO INCLUDES FORMING A PLURALITY OF PRIMARY DILUTION HOLES (98) IN THE FIRST PANEL (82) AND FORMING A PLURALITY OF SECONDARY DILUTION HOLES (100) IN THE SECOND PANEL (86). THE DILUTION HOLES ARE CONFIGURED TO DISCHARGE DILUTION AIR INTO THE SHELL.
