Product Description
 
In order to improve the boiler efficiency, boilers are gradually developed into tubular boilers to increase heat transfer area. The pot water flows from the pot barrel to the lower box through the downward tube, and is distributed to each tube bundle by the box body. The water in these tube bundles continuously absorbs heat energy and collects into the upper box body and then flows back into the pot barrel. We call the upper and lower box body headers. Header is an important part of the boiler, which is divided into upper header and lower header.
 
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.

 

 

Types

 

According to its location, there are upper header and lower header or inlet header and outlet header. According to the types of bundles collected, they can be divided into water wall headers, super-heater headers, economizer headers and so on.

 

Functions

Header is a pipe fittings for mixing working substances of boilers and ensuring uniform heating of working substances. Usually the furnace wall of industrial boilers is composed of rows of tubes(water-cooled walls), but the size of boilers is huge, and the structure is complex. It can not guarantee that the working substances in all tubes absorb the same heat. There are many differences in heat absorption in different parts. Installing headers can let the working substance in each tube converge here, and distribute to the next level of each pipe so as to reduce the thermal deviation so that the heat absorption, flow of the working fluid and cooling and thermal efficiency of the boiler are optimized and improved; in addition, the size, number and layout of the pipes in the upper, middle and lower parts of the boiler are different. The header is responsible for connecting each section to ensure smooth flow of working substances.

Features

 

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.

Application

CFB  distributing economizer header with high welding technique have water wall header, superheater header, economizer header and so on, it acts as collection, mixture, re-distributing working medium, as the structure, it can be classified as the end cover type( end enclosure) and necking down type.
