<P>PROBLEM TO BE SOLVED: To provide a reforming unit capable of reducing strain accumulation caused by stress deformation in the case of repeating start-up and shut-down of a reforming apparatus to extend fatigue life until reaching fatigue breaking. <P>SOLUTION: First and second flat dish-shaped containers each having a rectangular form by front view are fixed together by butting the whole circumferences of the peripheral collar parts of the vessels interposing a flat partition plate having a rectangular form by front view. A reforming material is placed in a first space between the first flat dish-shaped container and the partition plate, and a burner is extended along a specific side Ft of a second space between the second flat dish-shaped vessel and the partition plate at the side of the specific side Ft. In the reforming unit F having the construction, a specific side Fb3 is connected to crossing sides Fs1, Fs2 perpendicularly extending from the ends of the specific side in such a manner that the specific side Fb3 is connected to the crossing sides Fs1, Fs2 through a plurality of blunt corner parts Fa1 to Fa4 forming blunt angles at the crossing corners. <P>COPYRIGHT: (C)2012,JPO&INPIT |
