This patent describes a reflux condensing start-up system comprising: a steam generator having a heat-transfer fluid inlet for admitting a heat transfer fluid, a heat transfer fluid outlet for discharging the heat transfer fluid, a feed water inlet for admitting water and a steam outlet for discharging steam; a start-up vessel for heating water, a feed water inlet for admitting water and a steam outlet for discharging steam; a main steam line connected to the steam generator and start-up vessel steam outlets; a steam turbine having an inlet connected to the main steam line and an outlet; a steam condenser connected to the turbine outlet; a steam return line connected between the turbine outlet and an inlet of the condenser; a feedwater line connected between an outlet of the condenser and the steam generator feed water inlet; at least one feed water pump connected in the feed water line for pumping water; a start-up line connected between the feed water line at a point of connection downstream of pump, and steam return line; a start-up line valve in the start-up line; a steam generator inlet valve in the feed water line downstream of the point of connection; a start-up vessel inlet line connected between the start-up vessel feed water inlet and the start-up line; a start-up vessel inlet valve in the start-up vessel inlet line; and a start-up vessel outlet valve between the start-up vessel steam outlet and the main steam line; the valve can be selectively positioned and the start-up vessel heater can be operated to supply feed water to the start-up vessel to generate steam which is supplied to the steam line and generator to warm up and begin the operation of the turbine.
