Abstract:
1. A catalytic oxidation element for a gas turbine engine comprising: a pressure boundary element having an inlet end receiving a first fluid flow and an outlet end; an opening in an upstream portion of the pressure boundary element allowing fluid communication across the pressure boundary element between the first fluid flow and a second fluid flow to generate a combustion mixture flow; a catalytic surface disposed on a downstream portion of the pressure boundary element and exposed to the combustion mixture flow for at least partially combusting the combustion mixture flow; a support plate connected to the inlet end of the pressure boundary element; and a first baffle disposed downstream of the support plate and upstream of the opening and comprising a first passageway allowing passage of the pressure boundary element therethrough, the first baffle further defining a first space between the support plate and the first baffle for distributing the second fluid flow; wherein the pressure boundary element comprises a tube, wherein the opening is formed in the tube, and wherein the opening comprises a plurality of holes formed in the tube.
