PURPOSE: To make an evaporated fuel gas flow in a reactor uniformly, by setting of reactors laid at the upper part of an evaporator in a point symmetry in the sight of plane and making the center of a fuel feed pipe face to the center of the point symmetry.
CONSTITUTION: Plural reactors 3 are set in a point symmetry in the sight of plane at the upper part of an evaporator 1. A spray end 5a of a fuel feed pipe 5 is positioned at the central position of the point symmetry of an inlet 4 of the reactor 3 of point symmetry. A mixed liquid fuel dropped from the spray end 5a on the evaporator 1 is vaporized under heating by a burner 2 and rises towards an inlet 4 of the reactor. The vaporized fuel gas is evenly distributed to each inlet of the reactor 4 set at equal distances and sent to the reactor. Consequently, steam modifying reaction of each reactor 3 is made uniform, reaction efficiency is improved and occurrence of by-products is reduced.
