Function of a boiler in a fossil fuel energy chain

• Boil water to produce steam

• Rotate the turbine to generate mechanical energy

• Convert mechanical energy to electrical energy

A turbine in a fossil fuel energy chain

• is powered by kinetic energy of steam and rotates

• is powered by electrical energy and produces heat

• is powered by mechanical energy and generates electricity

A generator in a fossil fuel energy chain

• receives electrical energy and converts to heat

• receives mechanical energy from the turbine and converts to electricity

• Receives heat and converts to electrical energy
