A gas turbine engine combustor ( 26 ) including a primary combustion chamber ( 28 ), a mixer element ( 34 ), a mixing chamber ( 46 ) and a secondary combustion chamber ( 48 ). The primary combustion chamber receives a fuel oxidizer mixture flow ( 22 ) and discharges a partially oxidized mixture flow ( 32 ). The mixer element includes a plurality of flow channels ( 36, 38 ) for separating the partially oxidized mixture from a flow of an oxidizer ( 24 ) and producing a plurality of partially oxidized mixture flows interspersed with a plurality of oxidizer fluid flows. The mixer element may include a plurality of tubes ( 62 ) retained by an upstream tubesheet ( 70 ) and a downstream tubesheet ( 76 ). The mixer element may function as a heat exchanger to heat the oxidizer fluid flow and to cool the partially oxidized mixture flow upstream of the post-mixing chamber. |
