PROBLEM TO BE SOLVED: To provide a burner set for a reformer which keeps an operating state of a fuel cell system constant, keeping a reforming reaction in a reactor by preventing a fluctuation of a fuel supply condition due to a dew formation by using an unreacting exhaust gas from a fuel cell. SOLUTION: The unreacting exhaust gas from the fuel cell is supplied to a branch pipe, and heated with an endothermic member 16. When a combustion air which is supplied to an air preheat chamber 12 passes through a center reducing path 61, a fuel gas is mixed from the lower injection nozzle of the branch pipe, and this is passed through a second baffle plate 7 and a communicating tube 5, and is fired by supplying into a burner port. While heating the air in the air preheat chamber 12 by heat transferring the radiant heat of the flame in a combustion chamber 9 to a burner case and a burner cover, by transferring it from a burner plate 3 to the burner case and each communication tube, mixing chambers 10a, 10b, 11 are heated. |
