Abstract:
Disclosed is a combustion exhaust gas treatment device which enables long hours of continuous operation of a device by driving a scraper (30) for scraping a solid material adhered to the inner wall of a combustion treatment chamber (1) during the combustion treatment of exhaust gas to remove the solid material from the inner wall of the combustion treatment chamber (1). Specifically disclosed is a combustion exhaust gas treatment device, which is provided with a combustion treatment chamber (1) for combusting, decomposing, and treating exhaust gas, a main burner (MB) for supplying an air-fuel mixture in which fuel gas and supporting gas are mixed in advance so as to form flames within the combustion treatment chamber (1), and a scraper (30) for scraping the solid material adhered to the inner wall of the combustion treatment chamber (1), wherein the air-fuel mixture is adjusted within a combustion range and supplied to the main burner (MB) during the treatment for combusting, decomposing, and treating the exhaust gas, and during the non-operation of the scraper (30), and wherein the air-fuel mixture is adjusted out of the combustion range and supplied to the main burner (MB) during the treatment for combusting, decomposing, and treating the exhaust gas, and during the scraping operation of the scraper (30).
