。[Claim for Utility Model Registration] A common steam header that receives steam from multiple boilers and supplies it to a load, a pressure detector that detects the steam pressure within this steam header, and the steam pressure detected by this pressure detector. and a control device for controlling the number of boilers that operates sequentially starting from the No. 1 boiler in accordance with the decrease in combustion rate and according to priority, and each boiler has a low combustion state and a high combustion state. The unit control device includes a signal generating means that generates a control signal for controlling the operating state of the boiler in response to the start signal and the increase in the load, and a signal generating means that switches the boiler from a low combustion state to a high combustion state in response to the control signal. , or a switching means for switching the next boiler from the stopped state to the low combustion state, and the boiler with the lowest priority among the operating boilers is in the low combustion state and the other boilers are in the high combustion state. In this case, when a switching command signal is received from the switching means, the boiler with the lowest priority is switched to the high combustion state, the boiler with the next priority is switched from the stopped state to the low combustion state, and the boiler with the next priority is switched from the stopped state to the low combustion state, and and backup means for returning the lowest boiler to the low combustion state when the lowest boiler shifts to the low combustion state.
