A fluidized bed boiler is controlled by the processes of (1) setting a reference range of the installation height of the fluidizing medium and a reference range of the temperature of the fluidized bed within the fluidizing chamber; (2) sensing the installation height of the fluidizing medium, comparing the sensed height with the set reference range of the settled bed height, and supplying or discharging the fluidizing medium; (3) sensing the temperature of the fluidized bed, comparing the sensed temperature of the fluidized bed with the set reference range, re-setting the reference range of the fluidizing medium settled bed height at a higher height in accordance with the temperature difference by which the temperature of the fluidized bed exceeds the reference range, if any, and re-setting the reference range of the fluidizing medium settled bed height at a lower height in accordance with the temperature difference by which the fluidized bed temperature is below the reference temperature range, if any; and returning to the process (2).
