PROBLEM TO BE SOLVED: To provide a reformer capable of warming up in a short time when starting up, preventing catalyst degradation. SOLUTION: The reforming catalyst layer 3 is prepared in the tubular vessel 2. A reforming reaction takes place by introducing a reforming source gas into a gas introducing path 23 prepared in the upstream of the reforming catalyst layer 3. A supplemental air nozzle is installed in the gas introducing path 23, and air is introduced. Necessary heat is obtained by burning a portion of the reforming source gas. A warm-up supporting air nozzle 5 is operated when warming-up to feed air to the under pant of the reforming catalyst layer 3 where the condensed steam accumulates and becomes low temperature from the other parts, and to activate the catalyst early by generating heat. |
