How Steam Turbine Work

Gas Steam turbine is a first mover which converts potential energy of steam into kinetic energy then this kinetic energy is converted into mechanical energy in the form of rotation turbine shaft. Turbine shaft will be connected to driven mechanism directly or with the help of gear reduction. Steam turbine can be used in various industrial fields, for power plant and transportation.

To convert potential energy of steam into mechanical energy in the form of shat rotation shaft can be done in various ways, so steam turbine generally consists of three main types as following below:

1. Steam turbine impulse
2. Steam turbine reaction
3. Steam turbine combined (impulse-reaction)

During expansion process of steam in the turbine, some major losses occur during this process both inside loss and outside loss. Heat losses will decrease velocity, decrease pressure, decrease cycle efficiency and finally decrease power generator that will be generated by an electric generator.
