Description
Technical field
The utility model is related to a kind of new suspension type curtain wall structure, it is adaptable to large circulating fluidized bed boiler
A kind of suspension type curtain wall in burner hearth.
Background technology
With CFBB develop towards Large Copacity direction, it is necessary to its main circulation loop (burner hearth, separator and
Revert system loop) the middle more heating surfaces of arrangement.A kind of design conventional at present is to arrange suspension type screen formula in upper furnace
Heating surface.
CFBB suspension type curtain wall is in structure at present mostly using the parallel cloth of the flat-shaped screen piece of multi-disc
The mode of putting is designed, and upper furnace is arranged in aerofoil profile (wing wall) mode.With CFBB towards it is overcritical,
Ultra supercritical parameter direction is developed, and it needs to arrange that more suspension type curtain walls could meet Boiler Steam in burner hearth
The requirement of parameter and load.
If these suspension type curtain walls are all designed using flat-shaped screen piece, one is due to the increase for shielding piece height,
Screen piece rigidity can be caused to receive easily to shake in influence, running, flexural deformation is also easy to produce；Two, which be that screen piece is highly larger, goes back
The working medium flow in screen piece can be made longer, cause screen piece superheating phenomenon easily occur；Three be shield piece big difference in height easily occur by
The uneven phenomenon of heat, influences the service life of suspension type curtain wall.
Therefore, a kind of suspension type curtain wall that can guarantee that certain screen spacing, intensity are high is studied, and screen piece can be reduced
Highly, the intensity of increase screen piece, the device of elimination screen piece superheating phenomenon necessitate.
Utility model content
The utility model will solve the big difference in height band of the suspension type curtain wall screen piece of large circulating fluidized bed boiler
There is provided a kind of curved S types curtain wall of CFBB suspension type for rigidity, overheat and the life problems come.Recycle stream
Fluidized bed boiler uses the curved S types curtain wall of this suspension type, can reduce the height of screen piece, so as to increase the firm of screen piece
Degree, it is to avoid the deformation of screen piece and superheating phenomenon occur, and improve its service life；Furnace cavity can be better profited from simultaneously, is followed in master
More heating surfaces are arranged in loop back path, the requirement of Boiler Steam parameter and load is met.Including suspension type pendant superheater, again
The screen piece of hot device and water-cooling screen, described curved S types curtain wall is arranged in song by the pipe and fin for including circulation working medium
Shape S type screens piece is constituted.
Preferably, the curved S types in the curved S types curtain wall of described CFBB suspension type are by two and half
The tangent connected composition S-shaped of footpath identical quarter circular arc, and respectively tangentially have one section of extensional pipeline at this S-shaped two ends.
Preferably, the curved S types screen piece suspention in the curved S types curtain wall of described CFBB suspension type
At the top of boiler hearth of circulating fluidized bed, described S-shaped vertically faces the furnace wall for being disposed with smokestack.
Preferably, the curved S types screen piece in the curved S types curtain wall of described CFBB suspension type is upper
Hold and import header, lower end exit connection outlet header are connected at import.
Preferably, the song arranged in the burner hearth in the curved S types curtain wall of described CFBB suspension type
Shape S type screen pitch of fins boiler settings apart from b≤1/2W, W represents furnace depth or width.
Using the curved S types curtain wall of suspension type, the height of screen piece can be reduced, so as to increase the rigidity of screen piece, is kept away
Exempt from the deformation of screen piece and superheating phenomenon occurs, improve its service life；Furnace cavity can be better profited from simultaneously, in main circulation loop
The middle more heating surfaces of arrangement, meet the requirement of Boiler Steam parameter and load.

Embodiment
The utility model is described in further detail with reference to embodiment, following examples are to the utility model
Explanation and the utility model is not limited to following examples.
Embodiment：
Referring to the drawings 1~4：
The utility model provides a kind of recycle stream of the screen piece for suspension type pendant superheater, reheater and water-cooling screen
The curved S types curtain wall of fluidized bed boiler suspension type, the curved S types curtain wall includes water-cooling wall 1, and suspension type screen formula is heated
Face 2, header 3；Curved S types screen piece is arranged in by the pipe and fin of many circulation working medium and is constituted, at the import of pipe upper end
Connect import header, lower end exit connection outlet header；Import header is located on the outside of upper furnace；The curved S types are by two
The tangent connected composition S-shaped of radius identical quarter circular arc, and in one section of straight line of each tangent connection in this S-shaped two ends；Used
Cheng Zhong, the curved S types screen piece is suspended at the top of boiler hearth of circulating fluidized bed, and S-shaped faces the furnace wall for being disposed with smokestack；
The curved S types screen pitch of fins boiler setting arranged in burner hearth apart from b≤1/2W, W represents furnace depth or width.With reference to tool
The utility model is described body accompanying drawing；As shown in Fig. 2A and Fig. 2 B, CFBB suspension type of the present utility model
The basic structure of curved S types curtain wall is curved surface S types, and curved surface S type screens piece 2 is made up of pipe and fin, top and bottom
It is connected to header；
As shown in Figure 3 B, some curved S types screen pieces are with phase for arrangement form of the utility model in CFBB
It is equidirectional to be arranged in parallel in burner hearth.The curved nearly wall end of S types screen piece represents furnace depth away from boiler setting apart from b≤1/W, W
Or width.
Contrasted from Fig. 3 A with Fig. 3 B as can be seen that compared with traditional flat-shaped screen piece, curved S types screen piece can be with width
It increased, i.e., short transverse can reduce.The difference in height of screen piece can so be reduced, shorten the working medium stream in single cell
Journey, it is possible thereby to the generation of superheating phenomenon is avoided, the service life of extension screen piece.In addition, the reduction of difference in height can mitigate screen
Rocking for piece, while can increase the rigidity of screen piece, makes it be not likely to produce deformation in operation.
Furthermore, it is necessary to explanation, the specific embodiment described in this specification, is named the shape of its parts and components
Title etc. can be different.The equivalent or simple change that all construction, feature and principles according to described in the utility model inventional idea are done,
In the protection domain for being included in the utility model patent.The utility model person of ordinary skill in the field can be to being retouched
The specific embodiment stated is made various modifications or supplement or substituted using similar mode, without departing from the utility model
Structure or surmount scope defined in the claims, protection domain of the present utility model all should be belonged to.
