Abstract
A gas turbine engine combustor () including a primary combustion chamber (), a mixer element (), a mixing chamber () and a secondary combustion chamber (). The primary combustion chamber receives a fuel oxidizer mixture flow () and discharges a partially oxidized mixture flow (). The mixer element includes a plurality of flow channels () for separating the partially oxidized mixture from a flow of an oxidizer () 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 () retained by an upstream tubesheet () and a downstream tubesheet (). 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.
