The invention discloses a tail heated surface fixing device for a biomass CFB furnace, relates to a fixing device for fixing a heated surface coiled pipe, and aims to overcome the problems of excessive weight of a top steel beam and relatively higher overall height of a boiler caused by a traditional CFB boiler tail heated surface coiled pipe fixing mode. The tail heated surface fixing device comprises N support frames and N support lug plates, wherein N is a natural number larger than 1; the N support frames and the N support lug plates are positioned on two sides of the heated surface coiledpipe; the N support frames are distributed on a CFB tail flue protecting plate at intervals from top to bottom; the sections of the support frames are U-shaped; opening ends of the support frames aretransversely fixed on the CFB tail flue protecting plate; and the upper parts of the support lug plates are fixed with an elbow of the heated surface coiled pipe, and clamping ports are formed in thebottoms; and the clamping ports are clamped in closed ends of the corresponding support frames, so that the heated surface coiled pipe is fixed in a CFB tail flue.
Description
technical field [0001] The invention relates to a fixing device for boiler components, in particular to a fixing device for fixing a serpentine tube on a heating surface. Background technique [0002] The fixing of the serpentine tube on the heating surface at the tail of the existing biomass circulating fluidized bed CFB (Circulating fluidized bed) boiler is fixed by a large number of hanging tubes and serpentine tube clamps, but this not only causes the top The excessive weight of the steel beam will also make the overall height of the boiler relatively high. Contents of the invention [0003] The purpose of the present invention is to overcome the problem that the existing method of fixing serpentine tubes on the heating surface of the CFB boiler tail will not only cause the weight of the top steel beam to be too large, but also make the overall height of the boiler relatively high. The tail heating surface fixing device of the biomass CFB furnace. [0004] A tail hea...
