The steam separator acts like a drum in a natural circulation boiler. The fluid from this separator is recycled to the economizer inlet where it mixes with feedwater to maintain the minimum flow through the boiler furnace. Once minimum load is achieved, the startup system is put in warm standby for quick use when required. The steam from the separator passes through to the superheater and then on to the turbine. The startup operation parallels that of a drum boiler.
