Steam Turbine


Turbine is the generic given to most motor turbomachinery. These are fluid machines, by the using of  thah a fluid passes and it continuously delivers its energy through a paddle or impeller blades.

The turbine is a rotary engine that converts energy into mechanical energy of a stream of water, steam or gas. The basic element of the turbine is the wheel or rotor, with paddles, propellers, blades or buckets placed around its circumference, such that the moving fluid produces a tangential force behind the wheel and spins. This mechanical energy is transferred through a shaft to provide movement of a machine, a compressor, an electric generator or a propeller.

The turbines are made of one or two paddle wheels, known rotor and stator, the first being that, driven by the fluid drag the axis on which the rotational movement is obtained.

So far, the turbine is one of the most efficient engines in the world (about 50%) compared to internal combustion engines and even some electrical. Back in the 20s, some inventors, including one named Thyssen, patented a steam turbine which attributed a thermodynamic efficiency of 31%.

The term turbine is also applied, as the main component, the set of several turbines connected to a generator for producing electricity.
