Abstract
The invention provides an improved fixing structure for a superheater tube bank of a biomass fuel boiler, which has the advantages of simple structure, convenient processing, material saving and low manufacturing cost. The fixing structure comprises superheater pipes and is characterized in that the superheater pipes are connected with flat steels. The flat steels on adjacent superheater pipes are staggered and overlapped; one pass of the flat steels is arranged at intervals of 2 to 3 meters in the height direction of a superheater pipe panel; the positions of two adjacent flat steels are staggered along the height direction of the superheater pipe panel; and the adjacent flat steels are fixed by welding at intervals of 2 to 3 of the superheater pipes.
Description
(1) technical field
The present invention relates to the biomass fuel boiler technical field, be specially a kind of fixed structure of superheater tube bank of biomass fuel boiler of improvement.
(2) background technology
Because biomass straw fuel has lower ash fusion point, is prone to slagging scorification and fouling phenomenon, so the normal panelized construction that adopts wide pitch, parallel baffled of high temperature superheater.The fixing employing of the pendant superheater pipe of conventional boiler row was the form of pipe clamp pipe in the past; Thereby promptly along the tube panel short transverse arrange 2 pipes stretch to both sides again horizontal curvature get on to clamp pipe row, the shortcoming of this fixed form is a complex structure, resistance distributes uneven; To arrange that when tube panel is long several roads horizontal tube is all the more so more; Also influence the layout of heating surface area simultaneously, and the wall temperature of clamp is too high, except need with also causing booster the better tubing easily.Another kind of adoptable mode is the pipe clamp structure of conventional convection superheater, and its shortcoming is that pipe clamp need be made mould, and cost height and difficulty of processing are bigger; Out-of-flatness when the broad of section of jurisdiction; Yielding, also burn out easily during operation and come off, cause superheater vibration, dust stratification; Influence heat-transfer effect, then can't make on the technology when particularly tube pitch is very little at all.
(3) summary of the invention
To the problems referred to above, the invention provides a kind of fixed structure of superheater tube bank of biomass fuel boiler of improvement, it is simple in structure, and is easy to process, saves material, low cost of manufacture.
Its technical scheme is such:
It comprises superheater tube, it is characterized in that: be connected with band steel on the said superheater tube, the band steel on the said adjacent superheater tube is staggered to be overlapped.
It is further characterized in that: said band steel is every at a distance from 2m～3m setting together in the tube panel short transverse of said superheater tube; Along on the tube panel short transverse of said superheater tube, stagger each other in said adjacent twice band steel position; Said superheater tube is every at a distance from 2～3, and adjacent band steel welding is fixing.
Use the hot organ pipe row's of the present invention fixed structure, its beneficial effect is: it is simple in structure, and is easy to process, does not need processing mold, saves material, and cost is low, and its structure does not receive the tube panel structural limitations, also can not increase resistance and influence heat-transfer effect.

Fig. 2 is the A-A cross section cross-sectional schematic of Fig. 1;
Fig. 3 is the B-B cross section cross-sectional schematic of Fig. 1.
(5) specific embodiment
See Fig. 1, Fig. 3, structure of the present invention comprises superheater tube 1, on superheater tube 1, is welded with band steel 2.Band steel 2 staggered coincidences on the adjacent superheater tube; Band steel 2 is every at a distance from 2m～3m setting together in the tube panel short transverse of superheater tube; Stagger before and after each other along the adjacent twice band steel position on the tube panel short transverse of superheater tube (seeing Fig. 2, Fig. 3); Superheater tube is whenever fixing at a distance from 2～3 adjacent band steel welding, and 3 is solder joint.
Structure of the present invention in use; When arbitrary superheater tube desired to be out of shape to the left; Can receive with its adjacent superheater tube in left side at the stove rear to the constraint of band steel, each superheater tube all can receive the constraint of band steel on the adjacent superheater tube, thereby reaches the purpose that tube panel is fixing; In addition, stagger each other to install and played the effect that on short transverse, pins down in the position of every adjacent twice band steel, and the full wafer tube panel is fixed the most at last; And superheater tube is every at a distance from 2～3, and band steel welding in front and back is fixed, and promptly can not influence expansion, is more conducive to the tube panel shape that immobilizes again.
Claims (4)
1. the fixed structure of the superheater tube bank of biomass fuel boiler of an improvement, it comprises superheater tube, it is characterized in that: be connected with band steel on the said superheater tube, the band steel on the said adjacent superheater tube is staggered to be overlapped.
2. according to the fixed structure of the superheater tube bank of biomass fuel boiler of the said a kind of improvement of claim 1, it is characterized in that: said band steel is provided with together at a distance from 2m～3m in that the tube panel short transverse of said superheater tube is every.
3. according to the fixed structure of the superheater tube bank of biomass fuel boiler of the said a kind of improvement of claim 2, it is characterized in that: along on the tube panel short transverse of said superheater tube, stagger each other in said adjacent twice band steel position.
4. according to the fixed structure of the superheater tube bank of biomass fuel boiler of the said a kind of improvement of claim 3, it is characterized in that: said superheater tube is every at a distance from 2～3, and adjacent band steel welding is fixed.
