What does HRSG stand for in power generation?

In power generation, HRSG stands for Heat Recovery Steam Generator. This equipment is crucial for improving the efficiency of power plants, particularly those that operate on combined cycle systems. An HRSG captures waste heat from the exhaust gases of gas turbines to produce steam, which can then be used to drive a steam turbine, generating additional electricity.

The design of HRSGs allows them to maximize the utilization of energy resources, leading to lower fuel consumption and reduced emissions. They are often a key component in systems aiming for high efficiency, particularly in applications where both gas and steam turbines are employed. By effectively recovering waste heat, HRSGs optimize overall plant performance and contribute to energy conservation efforts in the industry.
