What happens to the steam after it has been used in a coal or oil-fired power station?

Once the steam has been used to turn the turbines it is then cooled by pipes containing cool water, from somewhere else, as they pass through the steam. Then the steam (which is now water after being cooled) returns back to the boiler to be turned into steam again, so it can begin the whole process again.
Different water cannot replace the used steam, it has to be condensed back to water, because only purified water can be used to turn the turbines, and it is too expensive to keep purifying more and more water.
The steam has to be cooled and returned to water somewhere away from the turbines, as even one droplet of water could damage them, due to their fast movement and delicacy, despite being big. If you got this question from the AQA GCSE science text book (where i got it from!) then the diagram (on page 266) is helpful, but not that detailed.

What are the energy transformations in a coal fired power station?
Coal is burned to produce heat, which then is transferred to water/steam, which produces mechanical power in the steam turbine, which produces electrical power from the generator
What does a generator do in a power station?
A coal-fired power station works by burning coal to give off heat, which heats water and produces steam. The steam is then used to push generator turbines; which generate energy.
How is power generated in a power station?
In a power station fuel is burnt to produce heat in the form of steam. This causes the turbine connected to a turbogenerator to spin resulting in the conversion of mechanical spinning energy to electrical energy, generating power.
How is peat turned into electricity?
Peat is made by the compaction and layering of partially decayed vegetation.
What are the ways in which power stations can be powered?
Power turbines are driven by steam. Steam can be raised by thermal, nuclear or geothermal processes. Wind and water can also drive a generator. The auxiliaries for a power station (which I think is what this question is asking) are typically powered by step down transformers within the power station. In nuclear power stations there are often standby-critical supplies which are driven by gas turbines or diesel generators.
What function does a boiler play in a power station?
This is where water is turned into steam at high pressure, which is then fed into the steam turbine
Why is fuel burned in the power station?
Fuel is burned to create steam. The steam turns the turbines, which produces electricity.
What does a boiler do in a coal power station?
A boiler in a coal power station is responsible for converting water into steam. The coal is burned in the furnace of the boiler, producing heat which is used to generate steam. This steam is then used to drive a turbine, which spins a generator to produce electricity.
What does a power stations turbine do?
A power station's turbine converts steam energy into rotary energy to drive the generator.

How a coal fired power station generates mains electricity?
The coal heats water into steam the steam runs turbines connected to generators.

What uses mechanical energy?
A power station generator uses mechanical energy produced by the steam turbine.
What does a hydroelectric power station look like?
Typically, hydroelectric power station appears to be a dam holding back a reservoir of water. Inside are turbines that turn the water to steam to produce electricity.
How is peat turned into electricity?
Peat is made by the compaction and layering of partially decayed vegetation.
