Description
Technical field
The present invention relates to the technical field of waste heat boiler, specially a kind of flexible sealing structure of waste heat boiler.
Background technology
At present in Gas-steam Combined Cycle power plant, waste heat boiler is located at behind gas turbine, utilizes combustion gas wheel
Machine discharges the heat of flue gas to generate steam, is power plant's inalienable part.
In vertical exhaust-heat boiler, flue gas generally to it is lower and on wash away heating surfaces at different levels.It is located at undermost high pressure in operation
Superheater surface module operating temperature highest leads to high-pressure superheater outlet header left and right, front and back and upper and lower three in operation
There is larger swell increment in a direction, wherein downward swell increment is larger, general rigid seal structure can not absorb header three
The swell increment in a direction.
Invention content
It is simple in structure in view of the above-mentioned problems, the present invention provides a kind of flexible sealing structure of waste heat boiler, it can be compared with
Solve the problems, such as that sealing structure can not absorb the larger three-dimensional expansion of header at header well.
Its technical solution is such：A kind of flexible sealing structure of waste heat boiler, which is characterized in that it includes being fixed on
First folded plate of heating surface pipe and the second folded plate for being fixed on holding furnace liner plate within the walls, first folded plate and second folding
There are expansion clearances between plate, are also connected by flexible high-temperature resistant plate between first folded plate and second folded plate, described
Flexible high-temperature resistant plate one end is flexibly connected first folded plate, the flexible high-temperature resistant plate other end other end by the first bolt
It is flexibly connected second folded plate by the second bolt.
It is further characterized by flexible high-temperature resistant plate both ends are provided with circular hole and kidney slot, the circular hole and institute
It states kidney slot to be alternatively arranged, be connect respectively with first folded plate and second folded plate by connecting plate, the kidney slot can
Realize flexible connection, ensureing can free wxpansion after first folded plate and second folded plate are heated.
First folded plate includes at least two with second folded plate, and arranged for interval, adjacent first folding
There are gaps between plate and second folded plate；
The flexible high-temperature resistant plate is glass mat and is a quarter circle structure, and both ends carry straight section；
First folded plate with the connecting plate being connect with the flexible high-temperature resistant plate, institute are mounted on second folded plate
It states and is both provided with connecting rib between connecting plate and first folded plate, the second folded plate；
First folded plate is welded to connect the heating surface pipe, and second folded plate is welded to connect supporting plate, the supporting plate
Holding furnace liner plate within the walls is connected by attachment screw.
After adopting the structure of the invention, there are expansion clearances between the first folded plate and the second folded plate, and pass through flexible resistance to height
Warm plate connection, there is front and back, upper and lower expansion space when expanded by heating, and kidney-shaped pore structure makes left and right also have expansion space,
Flexible high-temperature resistant plate absorbs swell increment, and the larger three-dimensional expansion of header can not be absorbed by preferably solving sealing structure at header
The problem of, and it is simple in structure；Further, it is connected by flexible high-temperature resistant plate between the first folded plate and the second folded plate so that expanding
Effect is good, will not make expansion movement larger because of the kidney slot on flexible high-temperature resistant plate, and as glass mat and is four
/ mono- circular configuration, both ends so that expansion effect is more preferable with straight section, and the setting of connecting rib increases the rigidity of connection.
