초록 ▼

The fuel gas reformer of a fuel cell power plant is provided with burner gas flow baffles which are annular in configuration, and which are concentric with the axis of the burner tube. The annular burner gas flow baffles form annular burner gas flow passages. The reformer has a plurality of annular arrays of catalyst filled tubes disposed in concentric rings about the burner tube. Each of the adjacent catalyst tube rings is separated from the next filled tube ring by one of the annular baffles. Burner gases are deflected downwardly and outwardly by the reformer housing top piece onto the catalyst filled tube rings. The baffles prevent inward flow of the burner gases and direct the burner gases uniformly downwardly along the catalyst filled tubes. Each ring of catalyst filled tubes is thus properly heated so as to enhance reforming of the fuel gas reactant.

대표청구항 ▼

A catalytic reformer assembly for converting raw hydrocarbon fuel to a hydrogen-rich gaseous fuel for use in a fuel cell power plant, said reformer assembly comprising: a) a housing having a cylindrical side wall, a first dome-shaped end wall, and a second end wall opposite said first wall; b) a burner in said housing positioned coaxially with said housing side wall, said burner opening through said housing second wall and including a hot gas tube which extends toward said first wall of said housing; c) a plurality of catalyst filled tubes disposed in said housing, each of said catalyst filled tubes having a first closed end directed toward the dome and an opposite second end, said catalyst filled tubes being arranged in a plurality of circular arrays each of which is concentric with said burner, said arrays being disposed in rings; and d) annular baffles comprising vertically extending cylindrical walls, each extending upwardly toward the dome-shaped end wall and arranged concentric with said burner, and interposed between said rings of catalyst filled tubes, said baffles being operable to intercept hot burner gases deflected from said dome-shaped end wall toward said second end wall, and to direct said hot burner gases away from said hot gas tube, and distribute said hot gases evenly through said rings of catalyst tubes toward said second end wall.
