NOVELTY - A miniature reforming hydrogen production reactor comprises burning tail gas heat exchange chamber (11), reforming tail gas heat exchange chamber, burning chamber, and reforming chamber. Fuel inputted by reactor inlet burns in the burning chamber, and increases temperature in the reactor. Tail gas produced in the burning chamber goes into the burning tail gas heat exchange chamber. The reactor has reforming raw material liquid that goes into built-in chamber of the reforming tail gas heat exchange chamber after warming up in the built-in chamber of the burning tail gas heat exchange chamber.    USE - The miniature reforming hydrogen production reactor is used for fuel cell micro power source's hydrogen resource system.    ADVANTAGE - The reactor has a compact structure and allows the temperature of catalytic burning reaction and reforming reaction to be easily controlled. Its running condition is stable.    DETAILED DESCRIPTION - The miniature reforming hydrogen production reactor comprises burning tail gas heat exchange chamber (11), reforming tail gas heat exchange chamber (13), burning chamber (15), and reforming chamber (16). The reactor has reforming air inlet, and fuel inlet linked with the burning chamber. Fuel (natural gas, alcohol, or gasoline) inputted by the inlet burns in the burning chamber, and increases temperature in the reactor. Tail gas produced in the burning chamber goes into the burning tail gas heat exchange chamber. The reactor has reforming raw material liquid (14) linked with the built-in chamber of the burning tail gas heat exchange chamber that is connected with the built-in chamber of the reforming tail gas heat exchange chamber. The reforming raw material liquid goes into the built-in chamber of the reforming tail gas heat exchange chamber after warming up in the built-in chamber of the burning tail gas heat exchange chamber. The burning tail gas and reforming tail gas are all heated by the pipe wall of the built-in chamber. Reforming air is mixed with the gas boiled by the reforming tail gas heat exchange chamber, and enters the reforming chamber to do reforming hydrogen production. The reforming and burning chambers contain reforming catalyst.    DESCRIPTION OF DRAWING(S) - The drawing is a schematic view of the reactor.
