Which teacher can explain the manufacturing equipment and processes for each component of a boiler?

You’d better buy the book \"Typical General Processes for Industrial Boilers\" published by the Shanghai Industrial Boiler Research Institute; after reading it, you will understand the manufacturing steps and processes for each component.

Let’s briefly talk about the boiler drum, header, end cap, pipes, economizer, and air preheater; please feel free to add anything or correct anything. Steam drum (drum section): Material inspection – Marking – Transferring the material’s steel stamp mark – Cutting to size – Assembly – Applying the welder’s identification stamp – Rolling into shape – Positioning weld on the longitudinal seam – Welding – Applying the welder’s identification stamp – Straightening (non-destructive testing) – Machining of end faces and grooves – Measuring the outer diameter; optional. Cylinder shell (section assembly): Positioning weld between cylinder sections – welding – stamping with the welder’s code – marking the center line of the cylinder body and the positions for pre-welded (embedded) components – Positioning weld between the cylinder body and one end cap – welding – stamping with the welder’s code – Positioning weld between the cylinder body and the other end cap – welding – stamping with the welder’s code – Non-destructive testing – Marking the positions for the pipe seat holes – Drilling the pipe seat holes – Positioning weld for the pipe seat assembly – Positioning weld for the pre-welded (embedded) components inside – Welding the pipe seat and the pre-welded (embedded) components inside – Stamping with the welder’s code – Heat treatment – Marking the positions for the pipe holes and vent holes – Drilling the pipe holes – Removing burrs and debris – Assembly or placement of internal components – Waiting for on-site assembly – Closing the manhole covers – Painting and packaging. Head: Material inspection – Marking – Transferring the material’s stamp – Cutting – Welding together – Stamping the welder’s identification mark – Grinding – Hot pressing forming – Defect detection – Marking the remaining thickness – Removing excess material from the head and manholes – Hot fitting of reinforcement rings – Welding – Stamping the welder’s identification mark – Machining of end faces and grooves – Measuring the outer diameter (optional).

Three instruments and one wall. Water wall, membrane tube banks with coatings, etc.: Currently, a combination of bare tubes and flat steel strips is commonly used. Material cutting, tube selection, arrangement, cutting, groove preparation, grinding, etc. Serpentine tube: There are three methods. The first is to weld elbow elements to straight tubes, the second is to continuously bend the straight tubes while extending them, and the third is to weld while extending them at the same time. Now, large boiler manufacturers should all be using the third method. Air preheater: Tubular type, generally a tube box structure assembled from thin-walled welded tubes and tube sheets; the materials used are ordinary and the manufacturing technology is not very advanced, so it can be produced by small factories. Rotary type – please add more details. .

I don’t know much about the manufacturing industry; I need to learn more from experts*

I recommend a book to the original poster. It was published by Harbin Institute of Technology. I’m not sure if it’s available on the ‘Boiler Manufacturing Technology and Inspection’ forum; I’ll search first. I can’t upload without it. This post was last edited by yang*aoguo1 on 2009-3-23 18:00]

Find a book on boiler technology, and you’ll have everything.
