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 happens in the turbines in a power station?
In a power station, the turbines are responsible for converting the kinetic energy from steam or flowing water into mechanical energy, which then drives a generator to produce electricity. As the turbines spin, they generate rotational motion that is used to generate electricity effectively.
Why is the overall efficiency of a steam power station very low?
The overall efficiency of a steam power station is low due to several factors such as heat loss in the boiler, turbine inefficiencies, friction losses, and incomplete combustion of fuel. Additionally, some energy is lost in the form of steam that is not converted to mechanical energy. These cumulative losses contribute to a lower overall efficiency of the power station.
in an oil power station how is heat generated?
In an oil power station, heat is generated by burning oil in a boiler to produce high-pressure steam. This steam is then used to drive a turbine connected to a generator, which converts the mechanical energy into electricity.
What happens inside the boiler of a powerstation?
Inside the boiler of a power station, fuel is burned to produce heat. This heat is used to convert water into steam, which in turn drives turbines connected to generators to produce electricity. The process of heating water to create steam efficiently generates power for various uses.
How does the coal fired power station operate?
In a coal-fired power station, coal is burned to produce heat, which is used to create steam. The steam then drives a turbine connected to a generator, producing electricity. The electricity is then sent out for distribution through power lines to homes and businesses.
What happens in the turbines in a power station?
In a power station, the turbines are responsible for converting the kinetic energy from steam or flowing water into mechanical energy, which then drives a generator to produce electricity. As the turbines spin, they generate rotational motion that is used to generate electricity effectively.
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
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.
Why is the overall efficiency of a steam power station very low?
The overall efficiency of a steam power station is low due to several factors such as heat loss in the boiler, turbine inefficiencies, friction losses, and incomplete combustion of fuel. Additionally, some energy is lost in the form of steam that is not converted to mechanical energy. These cumulative losses contribute to a lower overall efficiency of the power station.
What does a power stations turbine do?
A power station's turbine converts steam energy into rotary energy to drive the generator.
in an oil power station how is heat generated?
In an oil power station, heat is generated by burning oil in a boiler to produce high-pressure steam. This steam is then used to drive a turbine connected to a generator, which converts the mechanical energy into electricity.
what are 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 happens inside the boiler of a powerstation?
Inside the boiler of a power station, fuel is burned to produce heat. This heat is used to convert water into steam, which in turn drives turbines connected to generators to produce electricity. The process of heating water to create steam efficiently generates power for various uses.

What does a furnace and boiler do in a power station?
A furnace is used in a power station to burn fuel, such as coal or natural gas, to produce heat. This heat is then used to generate steam in a boiler. The steam is used to drive a turbine connected to a generator, producing electricity.
Describe the working of a thermal power station.?
In a thermal power station, fuel (such as coal, gas, or oil) is burned to produce heat, which is used to generate steam in a boiler. The high-pressure steam then drives a steam turbine connected to a generator, producing electricity. The steam is cooled and condensed back into water, which is then recirculated in the system.
How a coal fired power station generates mains electricity?
The coal heats water into steam the steam runs turbines connected to generators.
