    Abstract: A fuel cell (10) device includes a plurality of channels (32, 34) that have at least one unrestricted inlet (33), a conduit for directing a flow having a distribution pattern (84) to the unrestricted inlet (33) and an opening (40) between the conduit (50) and the opening (40) for receiving the flow distribution pattern (84), the opening having such dimension (L, W) in which the distribution pattern tends to normalize within the opening so that flow to each of the unrestricted inlet (33) tends to normalize across said opening.

    Abstract: An ignition system for a multi-burner heat exchanger assembly, a furnace, and a method using same are disclosed. The assembly may include a plurality of adjacent heat exchanger tubes, with a burner associated with each tube. All the burners may be lit with a single igniter and no source of secondary air. To do so, each of the burners may be provided so as to generate a swirling exit flow of combustion gases. One or more carryover tubes may also be connected between adjacent pairs of heat exchanger tubes or adjacent pairs of burners. The swirling flow generated by the burners causes hot combustion gases to move through the carryover tubes to thus carry the flame from one burner to the next. Not only can a single igniter be used, but a single flame sensor as well, while at the same time reducing nitrogen oxide emissions.

    Abstract: A fuel system for an energy conversion device includes a deoxygenator system with a multitude of flow impingement elements which are interleaved to provide a fuel channel with intricate two-dimensional flow characteristics. The flow impingement elements break up the boundary layers and enhance the transport of oxygen from the core of the of the fuel flow within the fuel channel to the oxygen permeable membrane surfaces by directing the fuel flow in a direction normal to the oxygen permeable membrane. The rapid mixing of the relatively rich oxygen core of the fuel with the relatively oxygen-poor flow near the oxygen permeable membrane enhances the overall removal rate of oxygen from the fuel. Because this process can be accomplished in fuel channels of relatively larger flow areas while maintaining laminar flow, the pressure drop sustained is relatively low.
