8. • It is a mechanical device that extracts thermal
energy from pressurized steam, and convert into
rotary motion.
• It has almost completely replaced the
reciprocating piston steam engine.
• It is particularly suited to be used to drive an
electrical generator.
9. According to steam pressure drop
IMPULSE TURBINE
• Maximum steam velocity( Impulse) is created at the inlet of moving blade Which means high
Kinetic Energy .This energy is utilized for rotation of moving blade.
• More pressure drop in guide blade.
REACTION TURBINE
• Reaction is created due to action of change of direction of steam through bucket. This thrust or
reaction causes the driving force.
• More pressure drop in moving blade.
10.
11. • Steam at high pressure & temperature is made to pass through a row of fixed blade
mounted on stationary body in casing.
• There will be drop in pressure of the steam across the fixed blade resulting to very high
steam velocity at the exit of fixed blade.
• The high velocity steam then impinges on another row of rotating blades mounted on
the rotor shaft.
• The impingement of high velocity steam generates driving force on these rotating blades
which rotate the rotor.
• A set of fixed blades and rotating blades mounted on the rotor is called stage of turbine.
14. • TURBINE CASING MACHINING SECTION :
Equipped with large size Planer, Drilling, Horizontal Boring, CNC Horizontal and Vertical Boring machine.
• ROTOR MACHINING SECTION :
Equipped with large size machining tools like Turning Lathe, CNC Lathes, Horizontal Boring Machine,
Special purpose FIR TREE groove Milling Machine.
• ROTOR ASSEMBLY SECTION :
Equipped with Indicating Stand, Small Size Grinding, Milling, Drilling m/c, Press and other devices for
fitting Rotors and discs.
• TURBINE CASING ASSEMBLY SECTION :
Machined casings are assembled and hydraulically tested by Reciprocating Pumps at two times the
operating pressure.
• TEST STATION :
Equipped with condensers, Ejector, Oil Pumps, Oil containers etc. required for testing.

25. • “An engineering degree is incomplete without practical knowledge and skills. An engineer is
expected to be a designer of dynamic world of innovation, for which practical experience matters
a lot.”
• I am extremely grateful to BHART HEAVY ELECTRICALS LIMITED,HARIDWAR for giving me the
opportunity to carry out my INDUSTRIAL TRAINNING at their facility. Special thanks to Er. MANISH
KUMAR CHAUDHARY, Er. OM PRAKASH, Er.JAIKESH KUMAR, Er. VIRENDRA SINGH, Er. RAKESH
KUMAR for his continuous support and guidance in being my mentor.
• It gives me a great pleasure to have an opportunity to acknowledge and to express gratitude to
those who were associated with my project training in BHEL, HARIDWAR.
