This presentation provides an overview of steam turbine manufacturing by Bharat Heavy Electricals Limited (BHEL). It discusses BHEL's history and awards, introduces steam power plants and the function of turbines. It then describes the key components of steam turbines like HP, IP, LP blades and their assembly. The control valves that regulate steam flow are also explained. In conclusion, it highlights the benefits of BHEL's steam turbine manufacturing process like improved safety, reduced breakdowns and a better work environment.

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.

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.
