Amit Kumar Das presented on industrial turbines. Turbines are rotary devices that extract energy from moving fluids like water, steam, gas or air and convert it into useful work. There are several types of turbines including water, steam, gas and wind turbines. A steam turbine in particular works by converting the thermal energy of steam into mechanical energy through its expansion and high velocity as it passes through nozzles and strikes the rotor blades, causing the turbine shaft to turn. Turbines have major applications in power generation and marine industries.

2. WHAT IS A TURBINE?
 A turbine is a rotary mechanical device
that extract energy from a fast moving flow
of water, steam, gas, air, or other fluid and
converts it into useful work.
 When steam is used as fluid, turbine is
called steam turbine. Same as gas, wind,
hydrolic turbine is nomenclature by the
fluid of gas, air & water.

3. BASIC TYPES OF TURBINES
• Water Turbine
• Steam Turbine
• Gas Turbine
• Wind Turbine
Although the same principles apply to all
turbines

4. MAJOR COMPONENT OF STEAM TURBINE:
 Casing
 Rotor
 Journal Bearing
 Thrust bearing
 Nozzle
 Guide blade
 Diaphragm
 Moving blade
 Shroud
 Rotor Chamber
 Gland seal (front & rear)
 Bearing seal ring-

5. WORKING PRINCIPLE OF STEAM TURBINE
In steam turbine, thermal energy of steam is
converted to a work (turning of turbine shaft)
through mechanical energy. There are two definite
steps in turbine operation.
 When the steam passes through the
nozzle, the steam pressure is expanded ,
but the velocity of steam is increased .
 The high velocity of the steam through a
nozzle strikes the rotor blade of the turbine
and turn to the turbine shape.
 As a result flow direction is change.

8. APPLICATION
 Turbines are used in a variety of industries
and applications, including marine
applications.
 For the generation of electricity in thermal
power plants.
