Abstract: A system for use in a gas turbine engine fuel supply has an internal fuel filter having an internal bore and an external surface. A chamber within the internal bore of the fuel filter for receives a fuel and allows fuel to pass radially outwardly across the fuel filter. An oxygen removal unit is outwardly of the external surface of the fuel filter, such that fuel passes through the fuel filter, encounters the oxygen removal unit such that oxygen can be removed from the fuel, an outlet port for removed oxygen, and a separate outlet port for fuel having passed over the fuel filter and the oxygen removal unit.

Abstract: A fuel delivery system for an energy conversion device includes a fuel deoxygenator and an oxygen scavenger module for removing dissolved oxygen and increasing the usable cooling capability of a fuel. Fuel emerging from the fuel-deoxygenating device flows into the oxygen-scavenging module where a second portion, smaller than the first portion of oxygen is removed from the fuel. The combination of the oxygen scavenger and the fuel deoxygenator provides an increase in removal of dissolved oxygen relative to the use of either device alone. The combination provides the desired increase in deoxygenation of fuel without the corresponding increase in device size.

Abstract: A fuel delivery system includes a fuel stabilization unit that receives vibratory energy for mixing fuel within fuel passages to improve the removal of dissolved oxygen from an oxygen containing fuel. A vibration generator transmits vibratory energy into the fuel stabilization unit to induce mixing of fuel. Vibratory energy is directed into the fuel to create enhanced mixing by inducing large-scale secondary flow motions that circulates fuel from a center flow area toward an oxygen permeable surface to improve overall fuel deoxygenation as more of the fuel is placed in adjacent contact with the oxygen permeable membranes.
