PURPOSE:To elevate temperature in the incinerator without giving a sudden temperature change by automatically controlling the amount of fuel supplied to a combustion chamber till a temperature elevating process and a subsequent combustion process after starting the incinerator. CONSTITUTION:When the temperature of the combustion chamber 2 detected by means of a temperature detector 21A reaches the setting temperature of a temperature switch 22A' after an opening of a fuel feed amount regulating valve 20 reaches a predetermined fixed value by the signals of a controlling block 24 for preheating, a signal selector 23 changes over an opening control circuit of the regulating valve 20, and controls so that the temperature of the combustion chamber 2 reaches the setting temperature of a regulator 22A. When operation is continued keeping the temperature of the combustion chamber 2 at the setting temperature of the regulator 22A, the temperature of a fluid bed layer 5 is elevated. When the detecting temperature of a temperature detector 21B reaches the setting temperature of a temperature switch 22B', the signal selector 23 changes over the control circuit to a control circuit which controls the opening of the regulating valve 20 by means of a regulator 22B so that the temperature of the fluid bed layer 5 reaches the setting temperature of the regulator 22B. |
