The height of low pendant superheater screen piece, so as to increase the rigidity of screen piece, it is to avoid the deformation of screen piece and superheating phenomenon occur, and improving it makes
Use the life-span.Described curved S types pendant superheater includes screen, large-size screen monitors and Late reworking before suspension type；Described curved S types screen
Formula superheater by more than two curved S types screen pieces it is in parallel it is arranged in columns constitute, described curved S types screen piece is by the pipe of more than 5
Son is arranged in curved S types screen and constituted.
Preferably, the curved S types screen piece in described curved S types pendant superheater is by two radius identical a quarters
The tangent connected composition S-shaped of circular arc, and respectively tangentially have one section of extensional pipeline at this S-shaped two ends.
Preferably, the bottom of the curved S types screen piece in described curved S types pendant superheater is provided with intermediate header, top
Provided with import header and outlet header.
Preferably, the S-shaped direction of the curved S types screen piece of each column in described curved S types pendant superheater is consistent, and adjacent two
The S-shaped direction for arranging curved S types screen piece is consistent or opposite.
Preferably, inlet pipeline is connected between the import header and intermediate header in described curved S types pendant superheater,
The same number of outlet conduit of inlet pipeline is connected between outlet header and intermediate header.
Preferably, the import header and outlet header in described curved S types pendant superheater are connected as a single entity or mutually only
It is vertical, on the outside of upper furnace.
Specifically, a kind of curved S types pendant superheater of the present utility model, including before suspension type screen, large-size screen monitors and after shielded
Hot device, lines up several columns by some curved S types screen piece parallel connections and constitutes.Described curved S types screen piece is arranged in song by many pipes
Shape S types screen and constitute.The bottom of the curved S types screen piece is provided with intermediate header, and top is provided with import header and outlet header.Institute
The import header and outlet header stated are connected as a single entity or separate, and on the outside of upper furnace.The import header is with
Between be connected with some inlet pipelines between header, it is same number of to be connected with inlet pipeline between the outlet header and intermediate header
Outlet conduit.
Using such scheme, with advantages below：
From such scheme as can be seen that the design of curved S types screen piece can be such that screen piece increased in width length, i.e.,
Short transverse can reduce, so can compared with smaller screen piece difference in height, increase screen piece rigidity, while shorten single cell in
Working medium flow, so as to avoid the generation of superheating phenomenon, the service life of extension screen piece.

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：
As shown in Figures 1 to 4, curved S types pendant superheater described in the utility model, including screen, large-size screen monitors before suspension type
And Late reworking, described curved S types pendant superheater lines up 2 row by 7 pieces of curved S types screen piece parallel connections and constitutes, described song
Shape S type screen pieces are arranged in curved S types screen by 12 pipes and constituted.The quantity of the curved S types screen piece and the number of the pipe
Amount is depending on the volume, amount of capacity of boiler.
The bottom of curved S types screen piece is provided with intermediate header 1, and top is provided with import header 2 and outlet header 3.Described enters
Mouth header 2 and outlet header 3 are connected as a single entity or separate, and on the outside of upper furnace.The import header 2 and middle collection
