Submerged Arc Welding Carbon Steel Boiler Fired Boiler Parts For Power Plant
 
Function
 
Header is guaranteed working medium mixing heating boiler working medium pipes usually industrial boiler furnace wall is made up of rows of tubes (water wall) together, but boiler huge volume, complicated structure, cannot guarantee that all the working medium in the pipe of heat absorption capacity is the same, different parts of heat absorption differs a lot, install header can let each pipe working medium inside converge here, the redistribution to the next level in the tube, so that we can reduce the thermal deviation, make the working medium heat flow cooling boiler thermal efficiency of boiler is optimized to improve;In addition, the size, quantity and arrangement of the pipes in the upper middle and lower parts of the boiler are different
 
Product Description
 
The headers of boilers include water-cooling hinders of boilers proper, economizer hinders, superheater hinders, etc. They function for gathering, mixing and redistribution in boiler systems. In structure, they include end cover hinders or necking hinders.
 
1 Headers form an important part of all types of boilers.
2 Steam from the generating tubes is collected in headers which are therefore always under pressure.
3 This pressure may vary from 300 psi to 2000 psi. Since headers are always under pressure, the utmost care is taken by us while fabricating them.
4 Depending on the generating capacity of the boiler the header sizes fabricated by us vary from 100 mm to 600 mm NB. The stubs of various sizes are very carefully welded to the main body of the header to provide the desired openings from the header.

Details

 

The pressures and temperatures that headers have to withstand depend on the component to which they are connected. A header connected to an economizer or to water wall panels is subject to less severe requirements on the material than a header connected to superheaters or reheaters.


Depending on the temperature and pressure of headers, Vallourec supplies tubes in carbon steel to high-alloy ferritic steels such as T/P91 or T/P92, with sizes ranging from 88.9 mm to 406.4 mm.

Classification

Enamelled Corrugated Sheet Baskets are a compact arrangement of profiled metal sheets placed in the Air Preheater rotor in two or more layers and plays the most important role in the process of heat recovery.
 
The bottom layer, or the cold end layer, is where the air enters and the flue gases are discharged, and is therefore, subjected to severe corrosion due to acid dew point. The Material of Construction and the Profile design of the Heating Elements depends on the operating conditions, quality and type of fuel, etc.
 
Parameters

Diameter(OD)

¢76mm~¢914mm

Diameter(OD)

23000mm

Temperature(℃)

300~1500

 

Application

Steam distribution headers are fabricated out of carbon steel or alloy steel seamless tubes. Customized or tailor made items are offered. Headers, after fabrication, are stress relieved to make the Steam distribution headers free from stresses. They are big pipe headers that transfer water from the downcomers to the risers through a combustion zone where the water gets partially heated to steam from the heat of fuel combustion.
