2. INTRODUCTION:
 BHEL is the largest engineering and manufacturing enterprise in
India in the energy related infrastructure sector today.
 BHEL was established more than 40 years ago when its first plant
was setup in Bhopal.
 BHEL is one of India’s nine larger Public Sector Undertakings or
PSUs ,known as the NAVRATNAS or the nine jewels .
 The wide network of BHEL's 14 manufacturing division, four
power Sector regional centre, over 150 project sites, eight service
centre and 18 regional offices.
 BHEL has already attained ISO 9000 certification for quality
management, and ISO 14001 certification for environment
management

3.  The power plant equipment manufactured by BHEL is based on
contemporary technology comparable to the best in the world and is
also internationally competitive.
 BHEL is the only company in India with the capability to make
simultaneous for power plants, defense and other applications.

5. BLOCK-3: TURBINE MANUFACTURING
SHOP
 HMS (Heavy Machine Shop)
 Assembly Section
 OSBT
 Turbine Section
 Blade Section

6. STEAM TURBINE:
 Turbine is an engine that converts energy of fluid into mechanical
energy .
 Steam turbine depends completely upon the dynamic action of the
steam.
 Steam turbine is steam driven rotary engine.

7. WORKING OF STEAM TURBINE:
Impulse Turbine:-
• steam is expanded only in nozzles.
• Blade passage of constant cross-section
area.
Reaction Turbine:-
• Pressure drop in fixed & moving blade.
• Blade passage of varying cross-section
area.

8. ROTOR AND CASING OF STEAM
TURBINE:
 HP (High Pressure)
 IP (Intermediate Pressure)
 LP (Low Pressure)

10. GAS TURBINE:
 Gas turbine have been used for electricity generation.
 The gas turbine obtains its power by utilizing the energy of burnt
gases & air which are at high Pressure and Temperature.

11.  For electricity generation, it is known as power turbine.
 For propulsion unit in aircraft, it is called aircraft turbine.

12. BLADES MANUFACTURING:
 Operations Performed On Blades:
 Inspection
 Cutting
 Milling
 Grinding on both the surface
o Machining Of Blades:
 Horizontal milling machine
 Central lathe machine
 CNC machine
 Vertical boring machine

13.  Mostly 500MW turbine blades are manufactured in this shop.
 Basically the design of blades is classified according to the stages of
turbine.
 The size of LP Turbine blades is generally greater than of HP
Turbine blades.

14. OVER SPEED BALANCING
TUNNEL:
Features:
 max. thickness of tunnel : 2500mm
 tunnel diameter : 9000mm
 min. vibration limit : 1micron
 over speed limit : 2500 to 4500 rpm
 rotor balancing of max. : 600Mw
rating
 type of pedestal : DH 90/ DH 12

15. CONCLUSION:-
 BHEL is the largest engineering and manufacturing enterprise in
India .
 The company manufactures 235 MW nuclear turbine generator sets
and in future it will 500 MW.
 BHEL is a major contributor of equipment and systems to
industries.
 At the all, till now BHEL is best in supply and manufacturing
products.
