PROBLEM TO BE SOLVED: To provide a steam supply system capable of reducing heat loss.SOLUTION: A steam supply system 1 comprises: a steam generating device 2 which generates steam; a steam supply passage 3 which sends the steam generated by the steam generating device 2 to steam utilization equipment 50; a steam superheater 4 which is installed on the steam supply passage 3 and superheats the steam generated by the steam generating device 2; and a control device 5 which controls the steam superheater 4. The control device 5 controls the steam superheater 4 on the basis of a parameter with respect to a dryness fraction of the steam generated by the steam generating device 2 so that the steam superheated by the steam superheater 4 has a predetermined degree of superheat. Thus, the steam supply system 1 can stabilize the degree of superheat of the steam in accordance with the dryness fraction thereof and thereby restraining generation of drain. Therefore, the steam supply system 1 can reduce heat loss associated with a portion of the steam to be emitted when discharging the drain. |
