How It Works: Combined Cycle Gas Turbine

While conventional (or common) thermal power stations only generate around 30-40% of the energy they could, combined cycle gas turbine power stations can generate around 50%! The combustion (or burning) of the gas directly turns the blades of a gas turbine but there is enough leftover heat in the exhaust gases to drive a steam turbine. The heat energy lost from conventional thermal power stations can also be used to heat spaces and water in industry, homes and business.
