PURPOSE: A steam reformer is provided to naturally lower the temperature of reacting gas based on heat exchanging without a separate cooling pipe and to improve reacting efficiency by activating reacting materials. CONSTITUTION: A steam reformer includes a raw material supplying part(110), a combustion gas supplying pipe(140), a reforming catalyst reacting part(150), a combustion gas exhausting part(160), a raw material transferring coil pipe(170), a high temperature converting catalyst part(180), and a low temperature converting catalyst part(190). The combustion gas supplying part discharges combustion gas through a burner. The reforming catalyst reacting part is arranged on the outer circumference of the combustion gas supplying pipe and implements a steam reforming reaction with respect to raw materials. The combustion gas exhausting part is arranged on the outer side of the reforming catalyst reacting part and downwardly transfers the combustion gas from the combustion gas supplying pipe. The raw material transferring coil pipe is wound around the internal space of the combustion gas exhausting part and supplies the raw materials into the reforming catalyst reacting part. The converting catalyst parts are arranged on the outer side of the combustion gas supplying pipe and implements aqueous gas converting reactions. |
