Mitsubishi Power, Ltd. | Heat Recovery Steam

2021-3-5 · Overview. A heat recovery steam generator (HRSG) is one of the major pieces of equipment in a gas turbine combined cycle power plant that boasts a high thermal efficiency and produces minimal CO 2 emissions. An HRSG is a kind of heat exchanger that recovers heat from the exhaust gases of a gas turbine to an extreme degree.

Flue Gas Recirculation: History and Uses - EnviroPower

Boilers run at a range of fuel rates but need to produce steam at a constant temperature. Heat transfer rates are low at lower fuel rates, producing cooler steam from the superheater. Recirculating flue gas effectively counteracts this problem by increasing the flow rate, and thus heat transfer, through the superheater coils.
