2. Introduction
• • A steam turbine is a device that extracts
thermal energy from pressurized steam.
• • Converts thermal energy into mechanical
work.
• • Widely used in power plants and industrial
applications.

3. Basic Principle
• • Works on the **Rankine Cycle**:
• 1. Water is heated to produce steam
• 2. Steam expands through the turbine
• 3. Energy is converted to mechanical work
• 4. Steam is condensed and recycled

4. Main Components
• 1. Boiler – Produces high-pressure steam.
• 2. Turbine – Converts steam energy into
mechanical work.
• 3. Condenser – Condenses steam back to
water.
• 4. Pump – Recirculates water to the boiler.

5. Working Process
• 1. Water is heated in the boiler to form steam.
• 2. High-pressure steam enters the turbine.
• 3. Steam expands and rotates turbine blades.
• 4. The rotating turbine drives a generator.
• 5. Steam is condensed and reused.

6. Types of Steam Turbines
• • Impulse Turbine – Steam hits the blades with
high velocity.
• • Reaction Turbine – Steam expands in both
fixed and moving blades.
• • Condensing and Non-Condensing turbines.

7. Advantages
• • High efficiency for large-scale power
generation
• • Low operating cost over time
• • Long operational life
• • Can utilize waste heat (in cogeneration)

8. Disadvantages
• • High initial setup cost
• • Requires large amount of water and fuel
• • Complex installation and maintenance
• • Not suitable for small-scale use

9. Applications
• • Thermal power plants
• • Nuclear power plants
• • Industrial co-generation systems
• • Marine propulsion
• • Oil refineries

10. Conclusion
• • Steam turbines are vital in electricity
generation.
• • Efficient and reliable for base-load energy.
• • Continuous innovation improving
performance and sustainability.
