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.
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
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.
