Abstract
The present invention relates to pulverized-coal fired boiler internal structure technical field, specially a kind of pendant superheater structure, it disclosure satisfy that the Steam Temperature Characteristics of boiler, it includes import header, outlet header and tube panel, described tube panel one end connects the import header, the other end connects the outlet header, the import header and the outlet header interval are arranged side by side, the roundabout setting of tube panel.
Description
Technical field
The present invention relates to pulverized-coal fired boiler internal structure technical field, specially a kind of pendant superheater structure.
Background technology
For the convection superheater of pulverized-coal fired boiler due to being limited by slagging condition, the flue-gas temperature of entrance can not be too high, and
When the steam parameter that boiler needs is higher, it is necessarily required to superheater to be arranged in the higher region of flue-gas temperature, so
Pendant superheater is just as the heating surface for being arranged in furnace outlet so that superheater can absorb the radiant heat of burner hearth, improve
The control characteristic of overheating steam temperature, universal application is had been obtained on the boiler of high capacity high parameter.But in low capacity senior staff officer
On several products, because the structure parallel tubes quantity of former pendant superheater is more, as shown in figure 1, again by size of burner hearth compared with
Small limitation, to consider the security of pendant superheater, while coutroi velocity, the area of pendant superheater can not be according to need
Increase so that low capacity boiler high parameter reaches more difficult.
The content of the invention
In order to solve the above problems, the invention provides a kind of pendant superheater structure, and it disclosure satisfy that the steam temperature of boiler
Characteristic.
Its technical scheme is such：A kind of pendant superheater structure, it includes import header, outlet header and tube panel,
Described tube panel one end connects the import header, the other end connects the outlet header, it is characterised in that the import header and
The outlet header interval is arranged side by side, the roundabout setting of tube panel.
It is further characterized by, and the roundabout upper end of tube panel is less than the import header and the outlet header.
After the present invention, the multigroup tube panel being arranged side by side originally and the structure for sharing inlet and outlet header are changed so that
Number of tubes arranged side by side can be adjusted flexibly as needed for tube panel, i.e., the roundabout number of turns, the arrangement of heating surface can be caused with full
The Steam Temperature Characteristics of sufficient boiler are needs.
Brief description of the drawings
Fig. 1 is prior art construction schematic diagram；
Fig. 2 is schematic structural view of the invention.
Embodiment
As shown in Figure 2, a kind of pendant superheater structure, it includes import header 1, outlet header 2 and tube panel 3, tube panel 3 one
End connection import header 1, other end connection outlet header 2, import header 1 and the interval of outlet header 2 are arranged side by side, and tube panel 3 is circuitous
Return and set, 3 roundabout upper end of tube panel is less than import header 1 and outlet header 2.Roundabout 5 circle, can be adjusted at any time as needed in figure
It is whole.This arrangement uses on the 220 tons of super-pressure reheat boilers and 75 tons of high-temperature high-pressure boilers of my company, and
Successful operation, steam temperature parameter reach target.
Claims (2)
