What is a Steam Turbine?

It is a machine that extracts thermal energy from the steam and converts it to mechanical work on a rotating shaft. The thermal energy is converted into kinetic energy through the expansion of the steam inside the turbine. The steam flows through properly designed fixed blades (stator) and moving blades (rotor) so that, according to the principles of impulse or reaction, they can efficiently transfer energy to the turbine shaft. During the expansion, there is a change in enthalpy due to the decrease in pressure and temperature of the steam, as well as the increase in its specific volume. Depending on the flow rate, this results in a certain power output on the shaft. Thus, the mechanical energy generated on the turbine shaft allows for the drive of various types of rotating equipment, such as fans, pumps, mills, compressors, and also 2 or 4-pole generators for electricity production. WEG has its own technology for the design and manufacture of impulse and reaction steam turbines, with an output power of up to 150 MW. The turbine frames are available in single or multiple stages, backpressure and condensing, with or without controlled extraction, and can operate with superheated or saturated steam.
