PROBLEM TO BE SOLVED: To provide a method of operating a regenerative combustion type exhaust gas treating device preventing the melting damage to a heat reservoir due to the abnormal combustion of a harmful component with a high concentration inside a thermal storage chamber by an easy and inexpensive means. SOLUTION: At least two thermal storage chambers 4 having a heat reservoir S are provided. One end of each of the thermal storage chambers is made to communicate with a combustion chamber 2 having a heating means 3, and the other end is made to communicate with switching valves V1a to V3c. Supplying the exhaust gas containing a harmful component to either thermal storage chamber through the switching valves and exhausting the treated gas with the harmful component heated and decomposed inside the combustion chamber from the other thermal storage chamber through the switching valves are subsequently switched by driving the switching valves so as to continuously treat the exhaust gas. On the other hand, the internal temperature of the heat reservoir is detected by a temperature measuring means TR, and the detected value is compared with the measured temperature that is predetermined. When the detected value becomes higher than the set temperature, the quantity of dilute gas supplied to the exhaust gas is controlled on the basis of this detected value. |
