<p><P>PROBLEM TO BE SOLVED: To provide a catalyst combustion device for reducing cost for operating a catalyst combustion furnace by extending the life of a catalyst therein. <P>SOLUTION: The catalyst combustion device operates the combustion furnace 11 with an inlet temperature T1 and an outlet temperature T2 as lower limit values before a concentration A1 of a gas component to be managed in released gas does not reach a management value for keeping the activity deterioration of the catalyst lower. After a gas temperature A1 to be managed in the released gas reaching a management value, it operates the combustion furnace 11 with the inlet temperature T1 and the outlet temperature T2 on the increase so that the concentration of the gas component to be managed reaches the management value. When the inlet temperature T1 and the outlet temperature T2 get to upper limit values, an alarm is issued for the replacement of the catalyst. <P>COPYRIGHT: (C)2004,JPO</p> |
