PROBLEM TO BE SOLVED: To stably supply steam by preventing a wasteful increase and decrease of a combustion amount, in a multiple-can installation system composed of a plurality of boilers and a number control device controlling the number of boilers. SOLUTION: In this boiler multiple-can installation system including the plurality of boilers 1 and the number control device 3, the number of priority orders determined in the number control device 3 is less than the installation number of the boilers 1, and part of the priority orders have the number of allocated boilers more than those of the other priority orders. The order for allocating a large number of boilers and the order for allocating a small number of boilers can be changed by setting. With respect to the priority order in a pressure section near a steam pressure value determined from a loading rate in the boiler multiple-can installation system, the number of allocated boilers is determined to be small, and with respect to the priority order in a pressure section far from the steam pressure value determined from the loading rate, the number of allocated boilers is determined to be large.
