Abstract:
1. A fuel deoxygenator assembly comprising: a housing having an inlet and an outlet, an exhaust tube disposed within said housing and having at least one open end extending from said housing; a first passage for fuel defined by a fuel channel spacer through said housing between said inlet and said outlet, wherein said fuel channel spacer includes a plurality of members extending from sides of said first passage to induce mixing and direct fuel toward sides of said frst passage; a permeable membrane spirally wrapped about said exhaust tube within said housing and disposed adjacent fuel flowing through said first passage, wherein said permeable membrane comprises a fluoropolymer coating supported on a porous backing with the fluropolymer coating defining said sides of said first passage; and a second passage defined by a membrane spacer and bounded on each side by the porous backing of the permeable membrane for communicating with said at least one open end of said exhaust tube and creating an oxygen partial pressure differential to draw dissolved oxygen from said fuel through said permeable membrane into said second passage and out said at least one open end of said exhaust tube.
