<p>PROBLEM TO BE SOLVED: To provide a boiler system capable of feedback controlling which enhances the pressure stability.SOLUTION: A boiler system 1 comprises: a boiler group 2 including a plurality of boilers 20 capable of burning by changing its burning rate; and a control part 4 that controls the combustion state of the boiler group 2 by the feedback control of the steam output outputted from the boiler group 2, in which the control part 4 includes: a burning rate calculation part 41 that calculates the burning rate of the boiler group 2; a proportional gain adjustment part 42 that regulates the proportional gain to lower as the burning rate of the boiler group 2 is lower and regulates the proportional gain to higher as the burning rate of the boiler group 2 is higher; and a feedback control part 43 that controls the combustion state of the boiler group 2 on the basis of the regulated proportional gain.</p> |
