Question

A combined cycle power plant has a greatly increased efficiency due to

A. using the steam generated to turn a steam turbine and generate electricity.
B. using a more efficient natural gas combustion gas turbine to generate electricity.
C. using the steam generated for heating nearby buildings.
D. using alternating fossil fuel sources.
E. using a generator with dual capacities.

Answer 1

a) using the steam generated to turn a steam turbine and generate electricity.The combined cycle power plant has a greatly increased efficiency due to

Step-by-step explanation:

The correct answer is option A. A combined cycle power plant has a greatly increased efficiency due to using the steam generated to turn a steam turbine and generate electricity.

In a combined cycle power plant, both a gas turbine and a steam turbine are used to generate electricity. The gas turbine burns natural gas directly to produce high-pressure gas that drives the turbine. The waste heat from the gas turbine is then used to generate steam, which powers a steam turbine.

This combination of gas and steam turbines allows for a higher overall efficiency compared to a traditional power plant that uses only one type of turbine.
