<p>PROBLEM TO BE SOLVED: To provide a control method of dust collecting equipment in a refuse incinerator which is capable of holding the temperature of exhaust gas at the inlet of the dust collecting equipment constantly within a proper range. SOLUTION: In a temperature control method of dust collecting equipment of a refuse incinerator which processes exhaust gas of an incinerator having a boiler one after another with an exhaust gas cooling device and the dust collecting equipment, the temperature of exhaust gas at the entrance of the dust collecting device is measured while the exhaust gas temperature 16 of the incinerator 1 or the exhaust gas flow rate 19 or the amount of steam generation 17 of a boiler 4 is measured. The amount of water spray of an exhaust gas cooling device 2 is operated based on these measurement results, thereby controlling the exhaust gas temperature at the entrance of the dust collecting equipment and furthermore, performing feedback control based on the exhaust gas temperature 8 at the entrance of the dust collecting equipment and feed forward control based on the exhaust gas temperature 16 of the incinerator 1 or the exhaust gas flow rate 19 or the amount of steam generation 17 of the boiler 4.</p> |
