Abstract
The invention improves system efficiency with no waste of heat held by a stopped boiler. A boiler system includes a boiler group having a plurality of boilers and a controller for controlling a combustion state of the boiler group. The controller includes a heat release determiner for determining whether or not the plurality of boilers includes a boiler releasing heat, a boiler increase determiner for determining, when the heat releasing boiler starts combustion and the heat releasing boiler and the other combusting boilers are combusted at equal load factors, whether or not the load factor is higher than a predetermined load factor, and an output controller for combusting the heat releasing boiler when the load factor is determined to be higher than the predetermined load factor.
