<p>In order to improve the pressure stability without repeatedly starting and stopping the boiler, this boiler system (1) is provided with a boiler group (2) comprising multiple boilers (20), and a control unit (4) which controls the combustion state of the boiler group (2), wherein for the boiler group (2), a fluctuation steam amount is set which indicates the capacity available for increases in the steam amount anticipated for sudden fluctuations in load request, and an increase minimum load ratio is set which indicates the load ratio at which an amount of steam corresponding to the load request is outputted with only the boilers (20) in combustion and without increasing the number of boilers; the control unit (4) increases the number of boilers (20) in combustion on the condition that the total available steam amount of the boilers (20) in combustion is less than the fluctuation steam amount and the load ratio of the boilers (20) in combustion is greater than the increase minimum load ratio.</p> |
