Description
Technical field
This utility model relates to a kind of boiler setting and seals fin.
Background technology
The furnace wall in existing boiler furnace region is overall a connection with water screen tube to form entirety, but due to water screen tube
Laying uneven, particularly at water screen tube bending area, the gap between water screen tube is strengthened so that this furnace wall shape
The sealing fin become has both sides defect: 1, owing to needing the position that sealing area is bigger, seals fin middle part and water
Between cold wall tube wall, distance can not get more greatly sufficiently cool, the most easily scaling loss and produce air leakage phenomena, make
Obtain water screen tube external environment condition herein to occur drastically to change.2, it is global formation due to existing sealing fin, it is impossible to along with
Expanding with heat and contract with cold of water-cooling wall and deform, easily there is crackle, thus in boiler repeatedly shutdown process, along with the flatulence of heat type of water-cooling wall is cold
Draw stricture of vagina progressively extends to wall section, causes water screen tube to be revealed.
Utility model content
This utility model provides a kind of stability improving safe operation of the boiler for the deficiencies in the prior art, effectively
Preventing and treating seal fin and leak out, reduce and expand with heat and contract with cold generation deformation, a kind of boiler setting increased the service life sealing fin,
It is particularly well-suited to subcritical, super (super-) critical boiler spiral water walls and vertical water wall intersection furnace wall seals, effectively solve
Determined helical water-cooled wall to the sealing scaling loss of the pipe bent position of intermediate header, the problem of tear.
This utility model adopts the following technical scheme that realization: a kind of boiler setting seals fin, including sealing fin originally
Body, between the size water screen tube adjacent with on boiler setting of described sealing fin body, the size in gap matches, described close
The material of envelope fin body is identical with the material of water screen tube, and described sealing fin body is welded between adjacent water screen tube,
The middle part of described sealing fin body is provided with opening, and described opening is fixed with the heat proof material plate sealing described opening.
Described heat proof material plate is fixed on the outside sealing fin body.
The size of described heat proof material plate uses monolateral spot welding mode more than the size of described opening, described heat proof material plate
It is fixed on sealing fin body.
Described heat proof material plate is heat-resisting steel sheet and plate.
Described sealing fin body is arranged on the elbow region of the helical water-cooled wall pipe of boiler.
The opening of described sealing fin body is 4-7mm with the width at the edge sealing the formation of this outer rim of fin.
The preferable width at the edge of described sealing fin body is 5mm.
Owing to using said structure, this utility model has the advantage that
1, fin body is sealed identical with water screen tube material, it is ensured that seal the weldability of fin body and water screen tube
Can, it is to avoid the situation that unlike material welding easily cracks occurs.
2, the middle part sealing fin body hollows out formation opening, and opening forms edge, edge with sealing fin body edges
For identical with water screen tube material with water screen tube welding and holding, opening is sealed by heat-resisting steel sheet and plate, on the one hand, heat-resisting
Steel plate can not be burnt, thus improves the heat-resisting quantity sealing fin body, on the other hand heat-resisting steel sheet and plate
Closure seals fin body middle cavity, it is to avoid air leakage phenomena;
3, heat-resisting steel sheet and plate and sealing fin body use monolateral spot welding mode, thus remain the deformation sealing fin body
Characteristic, makes sealing this physical ability of fin more adapt to the deformation that water screen tube produces.
4, heat-resisting steel sheet and plate is welded on the back side (i.e. hearth outer wall) sealing fin body, in unit operation, by burner hearth
Tiny structure heat-resisting steel sheet and plate tightly can be adsorbed and sealing on fin body.
In sum, this device, in boiler spiral water walls elbow region, utilizes middle part perforate to adapt to water-cooling wall
Deformation, seal fin body and use the material identical with tubing, it is to avoid the difference of unlike material welding performance and crack.
Use heat resisting steel sheet material to carry out blocking middle cavity, and only carry out monolateral welding with fin profile, it is thus possible to make sealing fin energy
More adapting to the deformation that bend pipe produces, heat-resisting steel sheet and plate is welded on the back side sealing fin, the tiny structure of available burner hearth so that it is with
Seal fin preferably to fit, effectively solve helical water-cooled wall to the sealing scaling loss of the pipe bent position of intermediate header, tear
Problem.

Fig. 1 is a kind of embodiment structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Fig. 3 is the structural representation that this utility model is arranged on boiler setting.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
As shown in Figures 1 to 3, a kind of boiler setting is with sealing fin, and including sealing fin body 1, described sealing fin is originally
Between the size of body 1 water screen tube 4 adjacent with on boiler setting, the size in gap matches, and in this example, described sealing fin is originally
Body 1 is arranged on the elbow region of the helical water-cooled wall pipe 4 of boiler, the material of described sealing fin body 1 and the material of water screen tube 4
Matter is identical, and described sealing fin body 1 is welded between adjacent water screen tube 4, and the middle part of described sealing fin body 1 is provided with out
Mouthful, the size of described heat-resisting steel sheet and plate 2 is more than the size of described opening, and described heat-resisting steel sheet and plate 2 uses monolateral spot welding mode to be fixed on
Seal on fin body 1.Described heat-resisting steel sheet and plate 2 is fixed on the back side (i.e. hearth outer wall side) sealing fin body.Described sealing
The opening of fin body is 5mm with the width at the edge 3 sealing the formation of this outer rim of fin.
Detailed description of the invention is, in FIG according to real space size and the position of bend pipe of on-the-spot bend pipe, measures sealing
The size of fin body 1 outline and the position of top circular arc.Then sealing fin body 1 centre position is hollowed out, and according to
Hollow out the size of position and shape cuts out size and the shape of heat-resisting steel sheet and plate 2.In Fig. 2, by monolateral for heat-resisting steel sheet and plate be spot welded to close
The back of envelope fin, and by the laminating of other positions closely.
