What is a Steam Turbine?

A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. 

Because the turbine generates rotary motion, it is particularly suited to be used to drive an electrical generator. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process.

 

Advantages

  • Robust & Reliable 

Triveni Turbines offers industrial steam turbines up to 100 MW that work across a wide range of pressure and flow applications.

  • High sustained efficiency

Advanced technology such as optimum combination of impulse and reaction blade path that maximises efficiency.

  • Excellent rotor dynamics

Solid forged rotor with integral discs to improve reliability.

Rotor dynamic analysis for lateral critical speeds for each shaft and bearing configuration.

  • Can be built in small units

Compact design for lower civil cost, quicker installation and easier maintenance.
