Abstract
A system that controls temperature in a heat recovery steam generator (HRSG). One heat recovery steam generator system may include a first exhaust path. The heat recovery steam generator system also may include a second exhaust path. The heat recovery steam generator system may include a first damper configured to selectively allow a portion of an exhaust to flow through the second exhaust path.
Claims20
A heat recovery steam generator (HRSG) system comprising:
- a plurality of heat exchangers;
- a first exhaust flow path configured to facilitate heat exchange between exhaust from a gas turbine and a first heat exchanger of the plurality of heat exchangers;
- and
- a second exhaust flow path configured to route a portion of the exhaust to bypass the first heat exchanger.
