Abstract:
1. A reformer comprising: a reforming unit; an oxidizing unit surrounding the reforming unit; and a burner nozzle assembly configured to mix an anode off-gas (AOG) with an oxidation fuel and to supply the mixed AOG and oxidation fuel to the oxidation unit, the burner nozzle assembly comprising a nozzle plate having an AOG nozzle at the center of the nozzle plate to supply the AOG to the oxidation unit and a plurality of oxidation fuel nozzles surrounding the AOG nozzle to supply the oxidation fuel to the oxidation unit, wherein the AOG nozzle has a diameter not greater than 2.5 mm, and each of the oxidization fuel nozzles has a diameter not greater than 1.5 mm and extends along a direction substantially parallel to a central axis of the nozzle plate having substantially the same diameter throughout a thickness of the nozzle plate; the burner nozzle assembly further comprising a channel unit coupling the AOG nozzle with an AOG introducer to allow the AOG to flow therebetween and coupling the oxidation fuel nozzles with an oxidation fuel introducer to allow the oxidation fuel to flow therebetween.
