PROBLEM TO BE SOLVED: To provide a boiler system for fixedly controlling pressure in a load unit using steam.SOLUTION: A boiler system 1 includes a unit count control apparatus 3 for controlling a combustion state of a boiler group 2 and storing steam with a target pressure in a steam header 6 and is configured to supply steam stored in the steam header 6 to a plurality of load units A1, A2, A3. The unit count control apparatus 3 includes: a storage part 5 for storing a required pressure P of steam to be used in each of the load units A1, A2, A3; using unit specification means 41 for specifying a steam using load unit using steam; supply amount acquisition means 42 for acquiring a supply steam amount (flow rate V) to the steam using load unit; pressure loss calculation means 43 for calculating pressure loss &Dgr;P following steam supply to the steam using load unit on the basis of a pressure loss coefficient and a supplied steam amount of a steam pipe; and target value setting means 44 for setting a target pressure TP on the basis of the required pressure P and the pressure loss &Dgr;P. |
