Abstract:
1. A cylindrical hydrogen generator, comprising: an outer case, an inner wall of which is provided with a layer of insulating material; a combustion unit; a reforming unit including two or more tubular reformers cylindrically disposed around the combustion unit, which is supplied with heat necessary for a steam-reforming reaction through radiation and convection of exhaust gas generated from the combustion unit, the tubular reformers being disposed using an upper connecting plate; a flame guide which divides an interior region of the hydrogen generator to define the combustion unit; a pressure loss induction structure in which an exhaust gas collecting passage communicating with an exhaust gas discharge pipe is formed by a partition wall, positioned between the tubular reformers and the outer case, along an inner circumference of the cylindrical hydrogen generator, and a plurality of orifices are radially arranged in the partition wall at regular intervals such that exhaust gas is evenly transferred to the exhaust gas collecting passage; and a guide wall formed to upwardly extend along an outer surface of the layer of insulating material with an interval from the upper connecting plate, wherein the outer surface of the layer of insulating material faces the tubular reformers; wherein the partition wall is arranged such that the exhaust gas passes between the guide wall and the partition wall before it flows into the orifices.
