14. CLASSIFICATION OF BLOCK-3

15. STEAM TURBINE
A steam turbine is a prime mover in which rotary motion is obtained by gradual change of momentum of steam
Modes of operation of steam turbine
Impulse principle
Reaction principle
Stages of steam turbine
H P ( High Pressure)
I P ( Intermediate Pressure)
L P ( Low Pressure)

16. MATERIAL Parameters of material selection Creep and rupture
Hot yield (0.2% yield stress)
Creep and rupture
Relaxation properties
Cyclic loading behaviour
Fatigue failure
Fracture toughness
Rate of crack growth
Resistance to scaling
Material used currently
13% Cr. Stainless Steel Bars
(C = 0.22%, Si = 0.5%, Mn = 0.8%, Cr = 13%, Ni = 0.8%, S = 0.020%,
P = 0.030%)

17. BLADING Entire turbine is provided with reaction blading
HP & IP blading as well as the initial stages of LP section are designed as reaction type stages
Last stages of LP moving blades are designed as twisted blades

18. BEARINGS
Journal bearing is being used in turbines to support the rotor
HP rotor is supported by two bearings
IP & HP rotors have a journal bearing each at end of the shaft

19. VALVES
HP turbine is fitted with two initial steam stop and control valves
IP turbine has two stop and control valves
Stop valve is used to immediately stop the supply of steam (emergency valve)
Control valve is used to control the steam flow rate by means of governor
These valves are arranged at right angles to each other in a common body
These valves are actuated by oil hydraulic mechanisms

20. GOVERNING SYSTEM The turbine has an electro-hydraulic governing system
The governing system permits run up control of the turbine up to the rated speed and keep speed swings due to variation in load
The electric system measures the variation in speed and output by means of sensors and send signals to electro-hydraulic converter.
The electro hydraulic converter then operates servomotor by hydraulic means to control steam flow rate

21. OIL SUPPLY SYSTEM
A single oil supply system lubricates and cools the bearings, governs the machine, operates the hydraulic actuators and safety and protective devices and drives the hydraulic turning gear
The main pump driven by turbine shaft draws oil from the main oil tank
Auxiliary oil pump maintains oil supply on start-up and shut down, during turbine gear operation and when the main oil pump is faulted
