Waste Heat Recovery Boiler VS Heat Recovery Steam

Oct 06, 2017 · A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle). The term HRSG refers to the waste heat boiler in a Combined Cycle Power Plant.
