Steam and gas turbine

In this article we will learn what is a steam turbine and its working process ,we will also know about its types and benefits of it to use in industrial level .Steam and gas turbine  used in different industries like thermal power plant ,ships and sugar industries ,it is also used in power plants. This is due to is tendency of steam turbine to occupy small place.

Steam is a primary mover in which rotary motion is obtained by the gradual change of momentum of the state the basic principle of steam turbine is the generation of high velocity expansion of high pressure steam Jet by the expansion of eye pressure steam and then conversion of kinetic energy as obtained into mechanical work on rotor blades.

Classification Of steam turbine

According to mood off steam action

Impulse turbine reaction turbine 

According to the direction of steam flow

Axial flow turbine radial flow turbine  

According to is as condition of steam

 Condensing turbine non condensing turbine 

 According to number of stages

Single stage turbine   multistage turbine

 According to pressure of steam 

High pressure steam turbine low pressure steam turbine medium pressure steam turbine 

Impulse turbine

First impulse turbine was invented in 1629  . this impulse turbine works on the principle of steam Jet impulse Steam turbine consist of nozzle and big wheel with blades mounted on it when the steam passes through the nozzle steam with high pressure air strikes On The Blade of the wheel this impact Moves the wheel into rotatory motion .This steam that after impinging glides over the concave surface of the blades and finally leave the turbine the action of the jet officer team impinging on the players is said to be an impulse.

Impulse turbine simple steam turbine which is used commonly .impulse turbines working and 

The basic part of the steam turbine given below

Nozzle          runner blade            casing

Nozzle in steam turbine is used to give steam direction and velocity. it is also used  to throw low and high steam pressure on impulse turbine blades .nozzle is kept near the blades so that air cannot resist in this process .Impulse turbine is consist of  this which is fixed on a horizontal shaft. Steam jet impacts on buckets through which buckets moves to the steam Jet direction, Blade motion rotate Runner to overcome the resistance damages blade surface kept very smooth.  the casing of the steam turbine is consist of turbine runner and blades is  casing  a locked and control steam moment  and it protect steam to not go into atmosphere so that no accidents occur during the process it is used as a safeguard for steam.

Advantages of steam turbines over reciprocating steam engine .High speed obtained through steam turbine, steam turbine have high efficiency of work, Steam turbine maintenance is very low very low space steam turbine takes to install it is so safe all parts are hidden in casing, one of the most important benefits of steam turbine is Torque of steam turbine remains constant
