Abstract

The invention discloses a steam cooling tube panel flue. The steam cooling tube panel flue comprises a tube panel flue body (3) formed by welding steam tubes (1) and fins (2), at least one rigid beam (17) perpendicular to the axis of the tube panel flue body (3) is arranged at the periphery of the tube panel flue body (3) along the axis of the tube panel flue body (3), the rigid beams (17) are slidably connected with the tube panel flue body (3) through lug plates (4) and connecting parts (5), and a hinge structure is arranged between each corner of the tube panel flue body (3) and the corresponding rigid beam (17); the bottom, the top and the two side faces of the tube panel flue are supported and hung through rigid hanging structures and constant hanging structures. According to the tube panel flue, the flue weight is greatly decreased, and the construction difficulty of a lining pouring material is greatly reduced; meanwhile, the tube panel flue can absorb heat by serving as a heated face, and therefore the arranging space and cost of a boiler are reduced. In addition, the problem that the steam cooling tube panel flue is difficult to support and hang is effectively solved through a flue supporting and hanging structure.

Description

technical field [0001] The invention relates to a flue structure, in particular to a gas-cooled tube panel flue used at the outlet of a cyclone separator and its support structure. Background technique [0002] For a long time, the outlet flue of the cyclone separator in the circulating fluidized bed (CFB) boiler is composed of steel plate + section steel + wear-resistant insulation lining material, which is not only heavy and difficult to construct, but also prone to wear-resistant insulation lining. The case where the lining material falls off. In addition, the flue only serves as a connection, and cannot be used as a heating surface to absorb heat, which wastes the layout space and cost of the boiler. After careful research by the applicant, the applicant proposed the concept of the steam-cooled tube-panel flue, changing the original steel plate flue to a steam-cooled tube-panel flue, thereby greatly reducing the weight of the flue and the difficulty of lining constructi...
