摘要： A control circuit (B) adapted to vary the vapor pressure in a boiler drum (17) which receives heat from a combustion chamber (3) in a fluidized bed boiler (A, C), in accordance with the quantity of heat recovered at the boiler drum (17), and improve a responsiveness for suppressing or controlling an increase or a decrease of the vapor pressure, which is caused by the variations of a vapor load. The vapor pressure in the boiler drum (17) is detected with a pressure gauge (20b), and the heat recovering air flow rate is controlled according to the vapor pressure, while a combustible material supply unit (12, 13, 14) for feeding combustible to the boiler (A, C) is also controlled accordingly.
