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.

Abstract translation: 系统可以包括被配置成将排气从发动机路由到热回收蒸汽发生器（HRSG）的排气导管。 系统还可以包括联接到排气管道的冷却剂供应。 冷却剂供应被配置为向排气管道供应冷却剂。 另外，该系统可以包括控制器，该控制器被配置为控制冷却剂供应以控制流经排气管道的排气从发动机到HRSG的排气温度，或由HRSG产生的蒸汽的蒸汽温度，或其组合 。 控制器可以被配置为在相对于系统的部件负载状态的满载状态下不同地控制冷却剂供给。
