It is cooled to liquid and fed back into the boiler for reheating.
The capacity of each steam turbines has more than 530 GW in over 6000 installed units. The steam turbines provide high reliability and sustained high efficiency.
among other things, to improve thermal efficiency and minimize ( transmission losses) as the steam cycles through the turbines, these are often l00% Heavy Duty cycles as in Powerhouse service and Nuclear submarines. turbines use superheated steam in order to avoid condensation inside, and, as a result, erosion of the blades. Superheated steam also contains more potential energy (expressed as an enthalpy).
A convergent-divergent nozzle is generally used in steam turbines. This is because it drives generators in producing electricity with the use of turbine rotors with curved axes.
The control stages are the stages at which steam is admitted to or extracted from the turbine. These "control" the output of the turbine.
In large turbines, a valve controls steam flow to groups of nozzles. The number of open valves controls the number of nozzles in use according to the load. A bar-lift or cam arrangement operated by the governor opens and closes these valves in sequence. Such a device is a multi-port valve. Using nozzles at full steam pressure is more efficient than throttling the steam.
In nuclear power plants, the turbines are turned by steam that is created through the heat generated by nuclear fission reactions. In geothermal power plants, the turbines are turned by steam created from the Earth's heat stored in the ground, which is accessed through wells and used to drive the turbines.
The energy in the steam is converted into mechanical energy by the turbines as it passes through them. This mechanical energy is then used to generate electricity, which can be distributed for various purposes.

Typically, the heat is used to boil water which produces steam. This steam is captured and pressurized before it is put through turbines. The steam spins the turbines which generates electricity. When the turbines are spun, however, it actually spins a coil of wire inside a magnet. This creates electricity... somehow.
The type of energy used in an electric power plant that uses steam to turn turbines is thermal energy. This is because the steam is produced by heating water using a heat source, such as burning coal or natural gas. The steam then drives the turbines, which in turn generate electricity through electromagnetic induction.

Steam turbines are external combustion engines.
moisture present in steam due to quality of steam.
The turbines in an electric power plant are turned by the kinetic energy of steam produced by boiling water. The high pressure steam flows through the turbine blades, causing them to spin and drive the generator to produce electricity.
