FUEL REFORMING APPARATUS AND METHOD OF STARTING SAME

PROBLEM TO BE SOLVED: To provide a fuel reforming apparatus wherein the packing of a heat insulation material such as ceramic fiber between instruments is made needless to reduce the volume of an heat insulation material, the apparatus is made small-sized and heat efficiency is improved, handling time required to form an insulation layer is remarkably reduced and the maintenance is facilitated. SOLUTION: The fuel reforming apparatus is constituted so that a unit composed of a reformer 1 and the associated instruments (a water evaporator 2, a feed fuel evaporator 3, a desulfurizer 4, a low temperature shift converter 5 and a selective oxidation CO remover 6) is covered with a vacuum heat insulation vessel 15 having the vacuum insulation layer formed between an inner cylinder 15a and an outer cylinder 15b.
