The utility model relates to the technical field of noise reduction devices, in particular to a noise reduction structure and a waste heat boiler. The noise reduction structure is arranged on a superheater of the waste heat boiler and comprises a noise reduction piece arranged on a finned tube of the superheater, and the noise reduction piece is located on the leeward side of the finned tube and arranged in the wind direction. The air flow carries noise, the air flow can generate large noise when passing through the finned tubes, the noise in the superheater is large, noise reduction is carried out in the superheater, the overall noise condition of the waste heat boiler can be effectively reduced, and the purpose of reducing noise of the waste heat boiler is achieved. Moreover, the noise reduction pieces are arranged on the finned tubes, compared with the mode that the noise reduction pieces are arranged on the outer side of the boiler body or the inner side of the boiler body or the outer portion of the chim
