Abstract: A reforming apparatus includes: an evaporation part that heats reforming water to generate steam; a reforming part having a reforming catalyst that is supplied with a mixture of the steam generated by the evaporation part and reforming fuel and generates reforming gas; a mixing part that is disposed on the lower side of the reforming part in the gravity direction and mixes the reforming fuel with the steam; a reforming fuel supply pipe having a desulfurizer for removing a sulfur content of the reforming fuel; and a reforming fuel connecting pipe connected at one end to the reforming fuel supply pipe and opened at the other end to the mixing part. A connecting part between the reforming fuel supply pipe and the reforming fuel connecting pipe is disposed above the mixing part in the gravity direction.

Abstract: A fuel gas processing apparatus includes a gas supply portion for supplying a fuel gas containing carbon monoxide and a catalytic combustion portion for catalytically oxidizing the fuel gas supplied from the gas supply portion. The fuel gas processing apparatus includes a carbon monoxide reduction portion for reducing the amount of carbon monoxide contained in the fuel gas before the fuel gas is supplied to the catalytic combustion portion to enhance combustibility of the catalytic combustion portion.
