What does a regenerator do in a gas turbine system?

A regenerator in a gas turbine system plays a crucial role in improving overall thermal efficiency by recovering waste heat from the exhaust gases. This process involves transferring heat from the hot exhaust that is otherwise lost to the environment and utilizing it to preheat the incoming air before it enters the combustion chamber. By raising the temperature of the air entering the combustion process, less fuel is required to achieve the desired temperature for efficient combustion. This not only helps in conserving fuel but also reduces emissions, contributing to a more sustainable operation of the gas turbine system.

The efficiency gains achieved by using a regenerator make it a significant component in many gas turbine systems, enhancing performance and reducing operational costs.
