Abstract
A gas turbine engine (10) includes a catalytic oxidation module (28). The catalytic oxidation module includes a pressure boundary element (30); a catalytic surface (32); and an opening (34) in the pressure boundary element to allow premixing of the fluids before the fluids enter a downstream plenum. In an embodiment, the pressure boundary element includes a catalyst-coated tube (58) having holes (68) formed therein to allow mixing across the tube. In another embodiment, the pressure boundary element includes a tubesheet (44) having a first fluid passageway intersecting a second fluid passageway to premix the fluids upstream of the outlet end of the tubesheet. In yet another embodiment, the catalytic oxidation module includes an upstream tubesheet (86) for mounting a tube inlet end (73) and a downstream tubesheet (78) for mounting a tube outlet end (72) so that the tube is slidably contained there between.
