What is the function of the reheater?

The reheater is a component in thermal power plants that increases the temperature of steam after it has passed through the high-pressure turbine and before it enters the low-pressure turbine. This process helps improve the overall efficiency of the power generation cycle by increasing the energy content of the steam, allowing for more work to be extracted from the steam as it expands through the turbines. By reheating the steam, the reheater also helps to prevent moisture formation in the low-pressure turbine, which can cause damage and reduce efficiency.
