Fuel deoxygenation system with non-planar plate members
A fuel system for an energy conversion device includes a multiple of fuel plates, oxygen permeable membranes, porous substrate plates, and vacuum frame plates which define a wave pattern configuration. The wave configuration enhances deoxygenation by increasing the efficiency and integrality due to higher surface volume ration, increase of flow turbulence, and minimal sharp edges which may otherwise damage the oxygen permeable membranes compared to other configurations.
1. A fuel system comprising:
a non-planar fuel plate;
a non-planar substrate plate; and
an oxygen permeable membrane mounted adjacent said non-planar substrate plate to define a non-planar fuel channel on one side of said oxygen permeable membrane and a non-planar oxygen receiving channel on an opposite side of said oxygen permeable membrane.
2. The fuel system as recited in claim 1 , wherein said non-planar fuel plate defines a wave pattern.
3. The fuel system as recited in claim 1 , wherein said non-planar substrate plate defines a wave pattern.
4. The fuel system as recited in claim 1 , wherein said oxygen receiving channel communicates an inert gas therethrough.
5. The fuel system as recited in claim 1 , wherein said oxygen receiving channel defines a vacuum therein.
6. The fuel system as recited in claim 1 , wherein said non-planar substrate plate supports said oxygen permeable membrane such that said oxygen permeable membrane defines a wave pattern.
7. A method of minimizing dissolved oxygen from within a fuel system comprising:
(1) mounting an oxygen permeable membrane adjacent a non-planar substrate plate to define a non-planar fuel channel on one side of the oxygen permeable membrane and a non-planar oxygen receiving channel on an opposite side of the oxygen permeable membrane; and
(2) flowing a sweep gas through the non-planar oxygen receiving channel along the oxygen permeable membrane to draw at least a portion of the dissolved oxygen from the liquid fuel flow and through the oxygen permeable membrane.
8. The fuel system as recited in claim 1 , wherein said non-planar fuel channel communicates a liquid fuel flow containing a dissolved oxygen along said oxygen permeable membrane.
9. The fuel system as recited in claim 1 , wherein said non-planar fuel channel defines a wave pattern.
10. The fuel system as recited in claim 9 , wherein said non-planar fuel channel communicates a liquid fuel flow containing a dissolved oxygen there along, a sweep gas flowing along an opposite side of said oxygen permeable membrane operable to draw at least a portion of the dissolved oxygen from the liquid fuel flow through said oxygen permeable membrane.
