How a condensing power plant works

Condensing power plants can run on different types of fuel, including uranium, coal, oil and biofuel.

Condensing power plants are designed to generate electricity as efficiently as possible. Unlike combined power and heating plants, they do not utilise the heat produced in the process. Condensing power plants fuelled by uranium are called nuclear power plants.


1. The steam furnace

In the steam furnace, water is heated and becomes steam.

2. The steam turbine

The steam is conducted into the turbine under enormous pressure and causes the blades to rotate.

3. The generator

The turbine drives a generator that produces electricity.

4. The transformer

A transformer converts the electricity into a high-voltage current. It is then sent to the power grid via cables.

5. The condenser

In the condenser, the steam is cooled and becomes water again. Hot waste water is pumped into the sea, and cold water is pumped back into the steam furnace.
