PURPOSE:To facilitate the support of catalyst and maintain said catalyst and its carrier at an optimum temperature by providing the heat-resistance carrier that carries the catalyst with multiple air ducts lengthwise, one end of said air ducts being opened to a passage for air being delivered from a compressor and the other end to the interior of a combustion chamber. CONSTITUTION:Multiple parallel air ducts 16 are routed lengthwise through cylindrical parts 13a, 13b, 13c. The air ducts 16 situated at the outer-most cylindrical part 13a are bent at their bottom to be opened 16a to the outside. The space defined by the cylindrical parts 13a, 13b, 13c and plates 14a, 14b is filled with catalyst 18. Part of air (a) delivered from a compressor passes through the air ducts 16 and cools a carrier consisting of components parts during such process. As a result, the catalyst 18 supported by the carrier is maintained at a suitable temperature, and NOx is not generated in the exhaust gas G, contributing to maintain clean exhaust gas from a gas turbine. Further, damages to the carrier are also prevented.
