Carbon Steel High Efficient High Temperature Resistant Header For CFB Boiler

Product Description

The steam boiler pressure part header with large diameter longitudinal welded pipe 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.
Technical parameters of customer design boiler pressure parts header for CFB boiler

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

Features

1. Strength calculation report with applied materials information.
2. 100%NDT(non-destructive inspection) report of steel plate, tube and welding rod.
3. 100%X-ray inspection report (welding seam): to ensure the quality of the entire boiler.
4. Hydraulic test report: ensure the standard working pressure and safety.

5.Excellent in welding quality, highly automatic, safe and reliable.

Classification

In bringing a boiler on the line with other boilers on a header system,certain precautionss are necessary to avoid water hammer and excessive temperature gradients in the piping. Adequate drainage and warming of the piping will eliminate the risk of water hammer. The judicious use of bypass valves around main header valves will avoid steep temperature gradients. Header drains should be operated. The steam line from the boiler to the header should be brought up to temperature by operating bypass and drain valves. When up to temperature and line pressure, the header valve may be opened wide and the bypass closed.

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.
