Abstract

PURPOSE:To control a temperature in high accuracy by a method wherein a corresponding value to the temperature in a fluidized bed is detected and an amount of floating mediums forming the fluidized bed in controlled by the corresponding value. CONSTITUTION:A fluidized bed temperature detecting portion Tn is provided in a portion wherein the fluidized bed 33 in a combustion furnace 1 is produced, an output thereof is compared with a signal from a preset temperature signal transmitting portion Tr, and a total amount of floating mediums kept in the combustion furnace 1 is adjusted by giving a signal or signals either to one of a fluid medium feeding amount operating transducer G1 and a fluid medium discharging amount operating transducer G2 or to both of them due to a reason whether a measured value of the temperature is larger than a preset value or smaller than the preset value. According to this method, when the measured value of the temperature is larger than the preset value, the temperature in the fluidized bed is lowered by increasing the amount of the floating mediums, and when the measured value of the temperature is smaller than the preset value, the temperature in the fluidized bed may be raised by decreasing the amount of the floating mediums, therefore, control of the temperature may be effected accurately and easily.
