PROBLEM TO BE SOLVED: To reduce in size and to improve performance of a thermal storage type combustion gas treating apparatus. SOLUTION: The thermal storage type combustion gas treating apparatus comprises ventilation inversion switching means v1 to v4 for alternately switching a ventilation route of a gas G to be treated to a first ventilation state for sequentially passing the gas G through a first thermal storage unit 5A, a combustion chamber 6 and a second thermal storage unit 5B in this order or to a second ventilation stage for sequentially passing the gas G through a second thermal storage units 5B, the chamber 6 and a first thermal storage unit 5A in this order, an untreated gas recovery switching means 9 for switching a guiding route of these gases to a recovery state for introducing the gas passed through a second thermal storage unit 6B in a first ventilation stage and the gas passed through the unit 5A in a second ventilating state to an exhaust stage for sending the gas to an exhaust passage 10 or to a recovery stage for introducing the gas to a tank 11, and a circulating means 12 for circulating the gas G introduced into the tank 11 to the unit 5A in the first state and to the unit 5B in a second state. |
