PROBLEM TO BE SOLVED: To provide a cooperation steam system which prevents system efficiency from deteriorating by a load factor of one part of steam boosting devices deteriorates.SOLUTION: A cooperation steam system 100 includes a plurality of steam systems 1A, 1B, 1C and a unit number control device 400. The plurality of steam systems 1A, 1B, 1C include: steam generating devices 10A, 10B, 10C; steam boosting devices 20A, 20B, 20C; and flow regulating valves 19A, 19B, 19C for adjusting a flow rate of a heat source fluid supplied to the steam generating devices 10A, 10B, 10C respectively. The unit number control device 400 includes: an average load rate calculation unit 420 for calculating an average value of load factors of the plurality of steam boosting devices 20, in the case where a difference of the load factors between the steam boosting device 20 whose load factor is the highest and the steam boosting device 20 whose load factor is the lowest exceeds a first threshold value; and a load factor control unit 430 for controlling an opening of the flow regulating valve 19 so that the load factors of the plurality of steam boosting devices become the average value.SELECTED DRAWING: Figure 3 |
