OEM Customized Color Boiler Manifold Headers Pressure Parts Industrail Using
Description
The main function is to collect the working medium, or redistribute the working medium to other pipelines through the collecting box, that is, to collect, mix and distribute the working medium, so as to guarantee the uniform distribution and uniform heating of working medium.The lower collector box, also known as the coke proof box, is located on both sides of the grate and directly in contact with the burning coal seam. The purpose of the lower collector box is to cool coke forming slag and not stick to the side wall.
| 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
| Material | Carbon steel,Alloy steel,Stainless steel. |
| Length | According to costumes requirements. |
| Temperature Range | 300℃~1500℃ |
| Diameter(OD) | 76mm~914mm |
Application
The CFB distributed economizer header with high welding technology includes water-cooled wall header, superheater header, economizer header, etc., which can be divided into end cover type (end cover type) and necking type as the working medium of collection, mixing and redistribution.
