Fume Thermal Oxidizers

Because they contain very little organics, a preheat exchanger downstream of the oxidizers is used to reduce fuel consumption by preheating the incoming fume stream. A Catalytic Oxidizer may be used if the organic level is fairly low and the fume stream is free from dust or any substance poisonous to the catalyst. An oxidizer for an inert based waste stream is no different from one for an air based fume stream except that air has to be injected for combustion purposes. Fumes can be air, inert or organic based. An air based fume stream is generally destroyed at a temperature of 1400 to 1600° F. Destruction efficiency can range from 90- 99%.
