PROBLEM TO BE SOLVED: To provide a boiler system which can suppress the corrosion of the boiler.SOLUTION: A boiler system 1 includes a boiler group 2 formed of a plurality of boilers 20 each having priority order, a steam gathering unit 50 which gathers steam, a steam pressure measuring means 51 which measures a steam pressure inside the steam gathering unit 50, a control unit 53 which controls the amount of combustion in a boiler 20 to be controlled, based on a steam pressure measured by steam pressure measuring means 51, and a priority order setting means 53 which sets a priority order for each of the boilers 20. The priority order setting means 53 puts high priority to the boilers 20 that meet the following conditions: (i) a pH value of boiler water detected by a pH value detecting means 43 is lower than a predetermined first threshold; and (ii) a total combustion time measured by a timer means 102 after a boiler body 21 is drained off the entire boiler water is shorter than a predetermined time. |
