Suited for treating odorous and smelly gases, such as those in chemical industry, spraying, and painting that contain substances like benzene and formaldehyde. The odorous gases are heated to temperatures above 600 degrees, where they undergo high-temperature combustion and decomposition to achieve harmless treatment. The exhaust gases can be used to generate hot air for drying or hot water for reuse through heat exchange. Meets the requirements for exhaust gas treatment in industries such as chemical plants, coating and painting drying, baking varnish curing, and panel coating drying.
