Abstract:
1. A heating medium supply system for a combined cycle gas turbine plant comprising: a heating system configured to heat a heating medium by sunlight; a heat exchanging device for generating steam to be supplied to a steam turbine of the combined cycle gas turbine plant, wherein said heat exchanging device is configured to heat feedwater using the heating medium supplied thereto from said heating system; a heating medium supply passage extending from an outlet of said heating system to an inlet of said heat exchanging device for circulating the heating medium to said heating system and to said heat exchanging device; a first heating medium temperature detecting device, a heating medium flow rate detecting device and a first heating medium flow rate controlling valve, which are provided on said heating medium supply passage at respective locations between said outlet and said inlet; and a control device configured to control the flow rate of the heating medium led from said heating system to said heat exchanging device by controlling said first heating medium flow rate controlling valve based on results of detections by said first heating medium temperature detecting device and said heating medium flow rate detecting device.
