Abstract
A heat rejection system is provided in a recirculating flow line, so that the steam production rate can be controlled from no steam production to maximum steam production for the gas turbine operating condition. For maximum steam production, the heat exchanger of the heat rejection system is bypassed so all the water is directed to the heat recovery unit (HRU). When no steam production is desired, all or a majority of the water is directed to the heat exchanger such that the heat absorbed in the HRU evaporator is equal to the heat rejected by the air cooled heat exchanger. Adjusting the flow split between these two limits allows the steam production rate to vary from no production to the maximum steam production capability corresponding to the gas turbine operating point.
