Abstract
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.
