PROBLEM TO BE SOLVED: To provide a boiler capable of performing feedback control which can enhance pressure stability.SOLUTION: A boiler 1 which can combust by changing a combustion rate includes a control device 70 for controlling a combustion state of the boiler 1 by feedback control of steam output outputted from the boiler 1. The control device 70 includes: a combustion rate calculation unit 71 for calculating the combustion rate of the boiler 1; a proportional gain adjustment unit 72 for adjusting a proportional gain in such a manner that the lower the combustion rate of the boiler 1, the lower the proportional gain, and the higher the combustion rate of the boiler 1, the higher the proportional gain; and a feedback control unit 73 for controlling the combustion state of the boiler 1 by feedback control based on the adjusted proportional gain. |
