Sometimes referred to as an After-Burner, the direct fired thermal oxidizer uses a specially designed burner to raise the temperature of a pollutant laden air stream to a predetermined combustion temperature. In operation, the contaminated process exhaust is ducted into a burner chamber. Heat applied by the burner oxidizes the VOCs and HAPs creating harmless products of combustion (water and carbon dioxide). The clean, heated exhaust gas can then be discharged to the atmosphere or sent through an optional heat recovery system.

The Anguil DFTO can achieve over 99% hydrocarbon destruction rate efficiency. To achieve this, the heated air is kept in the combustion chamber for a specified amount of time, called the residence or dwell time. At the inlet to the combustion chamber turbulence is generated to mix the pollutants and oxygen molecules. Proper mixing of the combustion air and process streams not only provides high destruction efficiencies but also safe operation. The Anguil design minimizes the risk of explosion and takes complete advantage of the VOC laden exhaust stream to minimize auxiliary fuel needs. An optional burner system is available to burn inert process streams directly in the burner as fuel.
