Problems solved by technology

The existing vertical gas turbine waste heat boiler flue sealing structure is composed of a fixed partition between the wallboard and the flue gas baffle, which is easily deformed after being heated during operation, especially in a waste heat boiler with high temperature and large expansion. The volume is large, which is not conducive to isolating the flow of smoke on both sides

Abstract

The invention provides a flue sealing structure of a vertical type gas turbine waste heat boiler, and the flue sealing structure can effectively isolate smoke from flowing out of a heating surface module when the boiler is in operational process. The flue sealing structure comprises a flue wallboard, a heating surface module, a tube plate, and a gas baffle, wherein the gas baffle is positioned above the heating surface module, and the gas baffle is welded on the tube plate which is arranged above the heating surface module. The flue sealing structure is characterized in that one side close to the heating surface module, of the flue wallboard, is provided with a fixed partition plate, and the two ends of a glass fiber wool connecting plate are respectively connected with the fixed partition plate and the gas baffle.

Description

technical field [0001] The invention relates to the technical field of waste heat boiler structure, in particular to a flue sealing structure of a vertical gas turbine waste heat boiler. Background technique [0002] In the flue of the vertical gas turbine waste heat boiler body, since there is a gap between the heating surface module and the flue wall panel, a flue gas sealing device must be installed between the heating surface module and the wall panel to prevent the flue gas from flowing out of the heating surface module . The existing vertical gas turbine waste heat boiler flue sealing structure is composed of a fixed partition between the wallboard and the flue gas baffle, which is easily deformed after being heated during operation, especially in a waste heat boiler with high temperature and large expansion. Large volume is not conducive to isolating the flow of smoke on both sides. Contents of the invention [0003] In view of the above problems, the present ...
