PROBLEM TO BE SOLVED: To enable improvement of boiler efficiency and reduction of power consumption of a blower by enabling supply of a constantly accurate amount of air to an inputted combustion amount without using an oxygen concentration sensor for exhaust gas.SOLUTION: In a boiler operated according to a predetermined amount of generated steam while controlling the amount of fuel supply and the amount of air supplied for combustion based on a detected value of a boiler pressure, the amount of air supplied for combustion in the boiler is adjusted based on a necessary combustion air amount calculated from an air supply amount actually measured by a wind velocity sensor or an air volume sensor provided in a suction duct of a blower and a value detected by a fuel flowmeter provided in a fuel supply pipe. |
