REPORT
PRESENTED BY:ANURAG HARSH

2. BHEL UNIT :TIRUCIRAPPALI
 Establishment : 1964
 Manufacturer of parts of boiler & different types of pipes.
 Plant details:

5. Manufacturing steps

4. High pressure boiler plant
Boiler:
A closed vessel in which fluid(generally water)is heated.
Transfer heat from a fuel source (oil, gas, coal) into steam.
The steam or hot fluid circulates out of the boiler for use in
various process or heating appliances.

5. WORKING OF BOILER

6. FIRE TUBE BOILER
The combustion gases pass inside boiler tubes, and heat is
transferred to water on the shell side.

7. Water Tube Boilers
Boiler water passes through the tubes while the exhaust
gases remain in the shell side, passing over the tube
surfaces.

8. MANUFACTURING
 Boilers standard (ASME Boiler &
Pressure Vessel Code (BPVC)
 History behind creation of standards
 Steps (design, fabrication ,inspection)

9. MANUFACTURING STEPS
 1ST
STEP:
Cutting of metal sheets

10. 2nd
step
 Rolling of cutting flat plate by hydraulic roller

11. 3rd
step
 Welding of rolled plates (x-ray use to check weld)

12. 4th
step
Now tube plate are machined by computer controlled
vertical milling machine for precise hole tube alignment
Then hand welding is carried out by appropriately coded
Welders.

13. 5th
step
Then all weld subject to pressure are
test by non destructive testing (NDT).

14. 6th
step
furnace, combustion chamber and front
tube plate are fitted to the boiler shell.

15. 7th
step
Then all parts are fitted adjacent to each other. On
completion of tubing boiler shell is subjected to hydraulic
test and inspection.

21. Water Tube

22. Fin Tube
A fin tube is a tube that has small fins around the outside surface.
These fins act as a filter and a mechanism to transfer heat from the
material inside the tube to the outside space or vice versa.
