PURPOSE:To improve reforming efficiency for methanol and to miniaturize a methanol reforming apparatus by forming internal and external annular spaces which are concentric and separated with a cylindrical metallic assembly having high heat conductivity and providing penetrating holes on the assembly for communicating the internal annular small chambers with the external annular small chambers via said cylindrical metallic assembly. CONSTITUTION:A burner 2 is attached to a top of a heat-insulated jacket kettle 1 of a methanol reformer, and a reforming section 3, a superheater 4 and an evaporator 5 are installed to the inside of the armor kettle 1. An annular chamber 8 is formed in the evaporator 5 between an internal wall 6, and a external wall 7, and the inside of the annular chamber 8 is separated with a cylindrical metallic assembly 9 having high heat conductivity, forming internal and external annular spaces 10, 11. The spaces 10, 11 are separated with horizontal ribs 16, 17 forming internal and external annular small chambers 18, 19, which are communicated with each other through penetration holes 15. Thus, the heat exchange capacity of the cylindrical assembly 9 is improved remarkably, so the reforming efficiency of a methanol reformer is improved remarkably. The apparatus is miniaturized due to the improvement of the heat exchange capacity. |
