The steam turbine is a turbine in which the potential energy of heated and compressed steam produced in a special device, a steam generator, or steam of natural origin (for example, from geothermal springs) is converted into kinetic energy (when the steam expands in the turbine blade cascades) and then into mechanical work on the rotating shaft.
