Temperature control manner of temperature control equipment and sludge incinerator of sludge incinerator

摘要

PPROBLEM TO BE SOLVED: To provide a temperature control device of a sludge incinerator and a temperature control method of the sludge incinerator capable of stably controlling a temperature to keep a temperature of a freeboard section at a high temperature while keeping a temperature of a sand layer section at a constant temperature. PSOLUTION: Model prediction control is performed in a state that temperatures of the freeboard intermediate section 3 and a freeboard upper section 4 have different target values under constraint conditions that the temperature of the freeboard intermediate section 3, the temperature freeboard upper section 4, a flow rate of fuel 12 supplied to a lower section 5 of a sand layer section, an air volume of flowing air 16 supplied to the lower section 5 of the sand layer, and air volumes of the air 17, 18 supplied to the freeboard intermediate section 3 and the freeboard upper section 4 are control input, a flow rate of the fuel 12, the air volume of flowing air 16, and air volumes of supplied air 17, 18 are control output, and the flow rate of the fuel 12 and/or the air volume of flowing air 16, and the air volumes of the supplied air 17, 18 are kept within prescribed ranges.
