INTRODUCTION

•Turbine is a prime mover that converts power of steam into mechanical energy.

Principle of Steam Turbine

Convert kinetic energy into mechanical energy.

By using fixed blades(nozzles) and moving blades.

Potential energy

Kinetic energy

Mechanical energy

Types of Steam Turbine

Impulse turbine Reaction turbine

Impulse Turbine

speed of steam is two times as fast as the speed blade.

force drops in fixed blades.

Reaction Turbine

It has no nozzle. Fixed blades are attached to the

casing and act as nozzle. Blades are like the wings of a plane.

Components of steam turbine

Blades ( Fixed and moving blades)

Casing

Rotor

Stop and control valve

Governor

Gear box

Working Principle

Working Principle

Problems in Steam Turbine

Blades rubs cause bending.

• Uneven cooling

• High temperature

• High rotor vibration

Problems in Steam Turbine

Oil lubrication

Misalignment

Corrosion fatigue

Conclusion

• Potential energy of steam is transformed into kinetic energy.

• Steam turbine is very useful for mechanical and generate electricity.
