*What is a turbine steam engine ?
- A turbine steam is a mechanical device that extracts thermal energy from pressurized steam, and converts it into rotary motion.  However, the steam turbine has many things in common with the combustion engine. The steam turbine changes chemically stored energy into mechanical energy, too. It's called a heat-force engine. The steam turbine works similarly to the water turbine

*How does it work ?
-The turbine steam changes chemically stored energy into mechanical energy. It's called a heat-force engine. The turbine steam engine works similarly to the water engine, which is known probably by everyone. -This picture shows how electrical energy generation using turbine steam involve three energy conversions, extracting thermal energy from the fuel and using it to raise steam, converting the thermal energy of the steam into kinetic energy in the turbine and use a rotary generator to convert the turbine's mechanical energy into electrical energy.



-This coupling leads to an excellent efficiency, which is even better than the efficiency of large diesel engines. This characteristic and the relatively favorable production make the steam turbine competitionless in power stations. Coupled with a generator and fired by an atomic reactor, they produce enormously much electric current. 

In the reaction turbine, the rotor blades themselves are arranged to form convergent nozzles. This type of turbine makes use of the reaction force produced as the steam accelerates through the nozzles formed by the rotor. Steam is directed onto the rotor by the fixed vanes of the stator. A pressure drop occurs across both the stator and the rotor, with steam accelerating through the stator and decelerating through the rotor, with no net change in steam velocity across the stage but with a decrease in both pressure and temperature, reflecting the work performed in the driving of the rotor.
