Abstract
The utility model relate to a kind of can the pendant superheater group of anti-rock and distortion, specifically, be the pendant superheater group with anti-rock and deformation performance in the boiler furnace using coal dust as fuel.It comprises at least two pendant superheater unit, and this pendant superheater unit is by rearranging into screen after many pipe bendings become U-shaped and forming.Many conduit entrances of pendant superheater unit are connected with import header, and many pipe outlets of pendant superheater unit are connected with outlet header, and described import header and outlet header are connected as a single entity and are in outside upper furnace.Be characterized in adjacent pendant superheater unit, many pipe outlets of a pendant superheater unit are all communicated with many conduit entrances of another pendant superheater unit respectively by tube connector.Adopt this pendant superheater group, rocking and being out of shape of pendant superheater can be prevented, avoid the pipeline in tube panel to be stuck, make tube panel be out of shape the generation of even booster fault, guarantee the normal operation of boiler.
Description
Technical field
The utility model relates to a kind of boiler.Specifically, be the pendant superheater group with anti-rock and deformation performance in boiler furnace using coal dust as fuel.
Background technology
All know in boiler manfacturing industry, in the burner hearth of pulverized-coal fired boiler and CFBB, all arrange pendant superheater group, this pendant superheater group contains and is no less than two pendant superheater unit.At pulverized-coal fired boiler, for preventing rocking and being out of shape of pendant superheater tube panel, reinforcement measure is mainly adopted to be fixed on the madial wall of burner hearth the differing heights both sides of tube panel.Although adopt this measure to have certain effect, but because burner hearth combustion wind sends into from differing heights, make the flue gas pressures in burner hearth very unbalanced, still thoroughly cannot solve rocking and problem on deformation of tube panel, thus shorten the service life of tube panel.And the pendant superheater used in CFBB, its entrance header and outlet header lay respectively at above and below tube panel, wherein, the header of below is arranged on outside the water-cooling wall of the antetheca of burner hearth, and tube panel one end is connected with the header of below through after the water-cooling wall of antetheca.The header of top is arranged on the upper outside of burner hearth, is connected after the water-cooling wall of the tube panel other end through burner hearth with the header of top.In boiler running process, because the medium in water-cooling wall is different with the medium temperature in pendant superheater tube panel, make water-cooling wall different from the downward swell increment of pendant superheater tube panel, the pipeline in tube panel can be caused to be stuck, to make tube panel be out of shape the generation of even booster fault, thus have impact on the normal operation of boiler.
Utility model content
Problem to be solved in the utility model be to provide a kind of can the pendant superheater group of anti-rock and distortion.Adopt this pendant superheater group, rocking and being out of shape of pendant superheater can be prevented, avoid the pipeline in tube panel to be stuck, make tube panel be out of shape the generation of even booster fault, guarantee the normal operation of boiler.
The problems referred to above to be solved in the utility model are realized by following technical scheme:
Of the present utility modelly the pendant superheater group of anti-rock and distortion can comprise at least two pendant superheater unit, this pendant superheater unit is by rearranging into screen after many pipe bendings become U-shaped and forming.Many conduit entrances of pendant superheater unit are connected with import header, and many pipe outlets of pendant superheater unit are connected with outlet header, and described import header and outlet header are connected as a single entity and are in outside upper furnace.Be characterized in adjacent pendant superheater unit, many pipe outlets of a pendant superheater unit are all communicated with many conduit entrances of another pendant superheater unit respectively by tube connector.
Take such scheme, have the following advantages:
As can be seen from the above scheme, due in adjacent pendant superheater unit, many pipe outlets of a pendant superheater unit are all communicated with many conduit entrances of another pendant superheater unit respectively by tube connector, and described import header and outlet header are connected as a single entity and are in outside upper furnace, make multiple pendant superheater unit be linked to be an entirety, thus avoid and rock.And the downward swell increment of tube panel in burner hearth presents free state, do not cause any strength that tube panel is out of shape, the pipeline avoided in tube panel is stuck, make tube panel be out of shape the generation of even booster fault, ensure that the normal operation of boiler.
Accompanying drawing explanation
Fig. 1 be of the present utility model can the pendant superheater group structural representation of anti-rock and distortion;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1;
Fig. 3 is the B-B cross-sectional schematic of Fig. 1.
Detailed description of the invention
As shown in Figure 1 and Figure 2 with shown in Fig. 3, of the present utility modelly the pendant superheater group of anti-rock and distortion at least two pendant superheater unit 1 can be comprised, the quantity of described pendant superheater unit 1, depending on volume, the watt level of boiler.
Described pendant superheater unit 1 is by rearranging into screen after eight pipelines 4 bend to U-shaped and forming.Eight pipeline 4 import departments of pendant superheater unit 1 are connected with import header 2, and eight pipeline 4 exits of pendant superheater unit 1 are connected with outlet header 5, and described import header 2 and outlet header 5 are connected as a single entity and are in outside upper furnace.For preventing rocking and be out of shape, in adjacent pendant superheater unit 1, eight pipelines 4 of a pendant superheater unit 1 export all by tube connector 3 respectively with eight pipeline 4 inlet communication of another pendant superheater unit 1, make multiple pendant superheater unit 1 be linked to be an entirety, thus avoid and rock.And the downward swell increment of tube panel in burner hearth presents free state, do not cause any strength that tube panel is out of shape, the pipeline avoided in tube panel is stuck, make tube panel be out of shape the generation of even booster fault, ensure that the normal operation of boiler.
The quantity of tube connector 3 is wherein equal with pipeline 4 quantity of pendant superheater unit 1, for simplicity, only depict between first pendant superheater unit 1 and second pendant superheater unit 1 of Fig. 2 between two pipelines, 4, second pendant superheater unit 1 and the 3rd pendant superheater unit 1 and only depict six pipelines 4.
