Purpose of Steam Turbine Steam turbine is prime-mover for electric power generation,
which converts heat energy of steam to mechanical energyof Steam Turbine Rotor.
This mechanical energy is utilized to spin rotor (magnet) ofthe electricity generator to produce electric power.

Steam Expansion Steam expands, whenever it is subjected either to lower
pressure or to a higher temperature. It is considered to be free expansion when the expanding
boundary is free from any resistance from the surrounding.Though the free expansion has no engineering application butit provides enough guidelines to the designers of steamturbines/engine to properly deal with steam operatingparameter to avoid any possibility of free expansion.
Expanding steam (thermodynamic System) does work onsurrounding irrespective of its being a solid, liquid or gasseparated by well defined boundary.
Expansion of steam in turbine is facilitated to do work onturbine blades mounted on the freely rotating shaft.

Principle of Steam TurbineWhen steam is allowed to expand through anozzle, then its heat is converted to kinetic energyof steam itself, which in turn converts into kineticenergy (mechanical energy) of Turbine Rotorthrough the impact (impulse) or in an other way,when it expands through Turbine Rotor Bladeswithout any change in its velocity then its heat isconverted directly in to kinetic energy (mechanicalenergy) of Turbine Rotor through reaction ofsteam expansion against the blades.

Reaction TurbineExpanding steam has to be accommodated in movingblades without any change in velocity by suitablyincreasing the space in the blade down stream, which isvery difficult and hence no steam turbine is constructed tobe pure reaction turbine.

Impulse - Reaction TurbineExpanding steam does work on surrounding bladesurface by virtue of its volume change and at the sametime incremental velocity of steam stream also doessignificant work on moving blades by impaction.

Hydraulic Turning GearThe function of the hydraulic turning gear isto rotate the shaft system at sufficient speedbefore start-up and after shutdown in orderto avoid irregular heating up or cooling downand also to avoid any distortion of theturbine rotors. The hydraulic turning gear issituated at the front end of the HP turbinefront bearing pedestal.

Casing ExpansionThe bearing pedestals are anchored to the foundation bymeans of anchor bolts and are fixed in position. The HPand IP turbines rest with their lateral support horns on thebearing pedestals at the turbine centerline level. The HPand IP casings are connected with the bearing pedestalsby casing guides which establish the centerline alignmentof the turbine casings. The axial position of HP and IPcasings is fixed at the HP-IP pedestal. Hence, when thereis a temperature rise, the outer casings of the HP turbineexpand from their fixed points towards Front pedestal.Casing of IP Turbine expand from its fixed point towardsthe generator.

Blade Performance of Pure Impulse Turbine
Wo = C2 Cos α2 (clockwise tangential component) Wi = C1 Cos α1 (anticlockwise tangential component) R2 < R1 & R2 = µ*R1
For smooth surface µ = 1 & R2 = R1
P = [Wi - (-Wo)]*u = [C2 Cos α2 + C1 Cos α1]*uC2 Cos α2 = R2 Cos β2 –u = R1 Cos β1 –uor C2 Cos α2 = C1 Cos α1 - u – u = C1 Cos α1 – 2uP = [C1 Cos α1 + C1 Cos α1 – 2u]*u = 2*u*[C1 Cos α1 – u]ηb = 2*P/C1**2 = 4*[(u/C1)*Cos α1 – (u/C1)**2]
