<p>PROBLEM TO BE SOLVED: To provide a boiler system controlling the number of boilers while considering superiority of boilers, with respect to one or more stage value control boilers and one or more proportional control boilers constituting a boiler group.SOLUTION: A boiler system 1 in which one or more stage value control boilers 20A capable of stably performing constant output, and one or more proportional control boilers 20B capable of performing output corresponding to fine load fluctuation, are coexisted, includes a control portion 4 for dividing a result of calculation of necessary steam amount by PI algorithm or PID algorithm by each PI component or PID component, allocating all or a part of the I component to one or more stage value control boilers 20A, and allocating the remaining I component after the allocation to the stage value control boiler, and the P component to one or more proportional control boilers 20B.</p> |
