The present invention relates to a combustion-type exhaust gas treatment apparatus which can be operated continuously over a prolonged period of time by operating a scraper (30) for scraping off solid matters adhering to an inner wall of a combustion treatment chamber (1) during combustion treatment of an exhaust gas. The combustion-type exhaust gas treatment apparatus has a combustion treatment chamber (1) for treating the exhaust gas by combusting and decomposing the exhaust gas, a main burner (MB) for forming a flame in the combustion treatment chamber (1) by supplying a mixture gas produced by premixing a fuel gas and an oxidizing gas, and a scraper (30) for scraping off solid matters adhering to an inner wall of the combustion treatment chamber (1). The mixture gas is adjusted within combustion range and supplied to the main burner during treatment for treating the exhaust gas by combusting and decomposing the exhaust gas and at the time when the scraper is not in operation, and the mixture gas is adjusted outside combustion range and supplied to the main burner (MB) during treatment for treating the exhaust gas by combusting and decomposing the exhaust gas and at the time when the scraper is in scraping operation. |
