Abstract: PROBLEM TO BE SOLVED: To provide a fuel stabilization system capable of removing dissolved oxygen from fuel to raise fuel temperature and being adapted to different demand conditions for removing oxygen. SOLUTION: This fuel stabilization system 10 is provided with a fuel tank 12 for supplying fuel to an engine 15 by a fuel pump 14. Dissolved oxygen is removed from fuel by a fuel stabilization assembly 16 provided with a plurality of oxygen removers 18, 20, 22, 24, 26 arranged in parallel. A part 30 of dissolved oxygen is removed from fuel by each fuel oxygen remover and is exhausted to the outside. Temperature of flowing-in fuel is within a scope of limit temperatures for preventing promotion of generation of insoluble substance under the presence of dissolved oxygen. Since fuel flowing out of the fuel stabilization assembly 16 contains less amount of dissolved oxygen, it is possible to heat fuel up to higher temperatures. Fuel is moved and heated by a heat transfer device 32. Efficiency of the engine is improved by improved temperature characteristic of fuel. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: A fuel system for an energy conversion device includes a multiple of non- metallic fuel plates, gaskets, oxygen permeable membranes, porous substrate plates, and vacuum frame plates. Intricate 3-dimension fuel channel structures such as laminar flow impingement elements within the fuel channel dramatically enhan ce oxygen diffusivity in the FSU. The fuel plates are manufactured from a relatively soft non-metallic material. The non-metallic fuel plates and gasket arrangement provide an effective sealing interface between the fuel plate and oxygen permeable membrane, since compression may be applied to the plates without damaging th e relatively delicate oxygen permeable membrane.

Abstract: A fuel stabilization system includes a first deoxygenator and a second deoxygenator both for removing dissolved oxygen from a hydrocarbon fuel. The first and second deoxygenators are arranged in parallel or series to sequentially remove a portion of dissolved oxygen from the hydrocarbon fuel. The arrangement of several deoxygenators for a single fuel stream improves removal of dissolved oxygen and provides for scalability of the fuel system to meet application specific demands. The arrangement also provides for the preservation of partial syste m functionality in the event of the failure of one of the deoxygenator modules .
