<P>PROBLEM TO BE SOLVED: To provide a boiler system that properly changes a combustion mode to further improve boiler efficiency. <P>SOLUTION: A boiler 20 includes a boiler body 21 in which a combustion process is carried out, and a supplied water temperature measuring means 50 which measures the temperature of water supplied to the boiler body 21. A combustion volume control means 4B has a combustion mode setting means 41 which sets a combustion mode as a mode related to a combustion volume of a boiler 20, on the basis of the temperature of supplied water measured by the supplied water temperature measuring means 50, and a supplied water temperature threshold setting means 42 which sets a supplied water temperature threshold as a threshold related to the temperature of supplied water, on the basis of the combustion mode set by the combustion mode setting means 41 and on the temperature of supplied water measured by the supplied water temperature measuring means 50. When the temperature of supplied water measured by the supplied water temperature measuring means 50 is equal to or lower than the supplied water temperature threshold, the combustion mode setting means 41 sets the combustion mode to a minimum combustion mode in which the combustion volume of the boiler 20 is the minimum. <P>COPYRIGHT: (C)2012,JPO&INPIT |
