Description
Technical field
The present invention relates to the technical field of waste heat boiler structure, specially a kind of waste heat boiler reheater tube panel arrangement knot
Structure.
Background technology
Because reheater tube panel temperature rise is larger, in order to avoid the header caused by swell increment difference between reheater difference pipe row
Stress problems of too, traditional reheater tube panel arrangement are an import headers, and one outlet header connects two rows and is heated
Facial canal, as shown in Figure 1.And for some special projects, reheater system need arrange three rows, even four array of pipes, and
An import header is now selected, one outlet header connects the arrangement of heating surface tube, very big safety problem, nothing be present
The problem of method overcomes header stress excessive.
The content of the invention
For above-mentioned header stress it is excessive the problem of, the invention provides a kind of waste heat boiler reheater tube panel arrangement tie
Structure, it can solve the problem that the header stress problems of too as caused by reheater difference pipe row's swell increment difference.
Its technical scheme is such:A kind of waste heat boiler reheater tube panel arrangement, it includes upper collecting chamber and next part
Case, heating surface tube is provided between the upper collecting chamber and the lower header, it is characterised in that the lower header includes two secondary collection
Case and a main header, the heating surface tube connect the upper collecting chamber and secondary header, and the secondary header is connected by expanding pipeline
The main header, the expansion pipeline away from flue gas airintake direction side is annulus line.
After structure using the present invention, using the pressure drop for the superheater pipeline for expanding pipeline increase low-temperature zone, so as to increase
The flow of hot arc reheater pipe, the tube wall temperature of hot arc pipe is reduced, make the tube wall temperature of hot arc pipe and cold section of pipe
More closely, swell increment is also more nearly, it is achieved thereby that eliminating header stress.
Brief description of the drawings
Fig. 1 is prior art construction schematic diagram;
Fig. 2 is the structural representation of the embodiment of the present invention one;
Fig. 3 is the structural representation of the embodiment of the present invention two.
Embodiment
Seeing Fig. 2, shown in Fig. 3, a kind of waste heat boiler reheater tube panel arrangement, it includes upper collecting chamber 1 and lower header 2,
Heating surface tube 2 is provided between upper collecting chamber 1 and lower header, lower header 1 includes two secondary headers 3 and a main header 4, heating surface
Pipe 2 connects upper collecting chamber 1 and secondary header 3, secondary header 3 connect main header 4 by expanding pipeline 5, away from flue gas airintake direction side
Expansion pipeline 5 be annulus line, it can be seen that in embodiment one three row's heating surface tubes 2 annulus line length
It is different from the annulus line length of four row's heating surface tubes 2 in embodiment two, for different reheat systems, it is only necessary to adjust swollen
The length on tensioner ring road, you can realize hot arc, cold section of heating surface tube working medium flow science distribution, header stress is eliminated so as to realize
Purpose.
Claims (1)
1. a kind of waste heat boiler reheater tube panel arrangement, it includes upper collecting chamber and lower header, the upper collecting chamber and it is described under
Heating surface tube is provided between header, it is characterised in that the lower header includes two secondary headers and a main header, it is described by
Hot facial canal connects the upper collecting chamber and secondary header, and the secondary header connects the main header by expanding pipeline, entered away from flue gas
The expansion pipeline of gas direction side is annulus line.
