Fuel cell power plant fuel processing apparatus

An integrated fuel processing apparatus for a fuel cell power plant comprising:

• a containment vessel in the shape of a substantially cylindrical shell;
• a division plate dividing said containment vessel into an upper gas reformer portion and a lower shift converter portion;
• a burner arranged to discharge combustion gas into said upper portion;
• a plurality of reactor tubes containing catalyst and located in heat exchange relationship with said combustion gas;
• a process gas flowpath through said reactor tubes;
• a combustion gas outlet plenum located for receiving combustion gas after the heat exchange relationship with said reactor tubes, and furthermore located below said reactor tubes and above said division plate;
• a combustion gas outlet for fluidly connecting said combustion gas outlet plenum to the exterior of said vessel;
• a process gas reactor outlet plenum located within said vessel below said division plate;
• reactor outlet tubes passing from said reactor tubes through said combustion gas outlet plenum, said division plate, and to said process gas outlet plenum;
• a shift converter within said vessel, containing a bed of catalyst and connected to receive process gas from said process gas outlet plenum;
• and
• a process gas outlet line arranged to receive process gas from said shift converter and convey it to the exterior of said vessel.
