  • System and method for controlling coolant supply to an exhaust gas
    Patent number: 10267185
    Abstract: A system may include an exhaust conduit configured to route an exhaust gas from an engine to a heat recovery steam generator (HRSG). The system may also include a coolant supply coupled to the exhaust conduit. The coolant supply is configured to supply a coolant to the exhaust conduit. Additionally, the system may include a controller configured to control the coolant supply to control an exhaust temperature of the exhaust gas flowing through the exhaust conduit from the engine to the HRSG, or a steam temperature of steam generated by the HRSG, or a combination thereof. The controller may be configured to control the coolant supply differently in a full load condition relative to a part load condition of the system.
