摘要： A generating system is presented that includes a steam generator, a separator coupled to the generator, a supply providing feed water, a start-up system coupled to and receiving the feed water, and a recirculation system coupled to the start-up system. The steam generator operates in a plurality of operating modes. In one mode the steam generator generates a flow of steam and fluid. The separator separates the flow into components of steam and fluid. The recirculation system receives the feed water from the start-up system and provides a required flow to the steam generator during at least one mode. The recirculation system includes an ejector. The ejector induces a portion of the fluid from the separator into the recirculation system, mixes the induced fluid with the feed water to provide a recirculation flow, and the recirculation system provides the required flow to the steam generator including the recirculation flow.
