The Anguil Direct Fired Thermal Oxidizer (DFTO) thermally destroys Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs) and odorous emissions often discharged from industrial exhaust stacks or chemical processes.
It is an ideal abatement technology for process streams heavily laden with pollutants or intermittent batch processes where the oxidizer can come on-line relatively quickly. With a flexible and user-friendly design, the Anguil DFTO offers low capital cost with high destruction efficiency and reliable operation.

HOW DOES A DFTO WORK?
Sometimes referred to as an afterburner, fume incinerator or enclosed flare, the DFTO 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 and from VOC exotherm oxidizes the VOCs and HAPs, creating less harmful 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 accomplish 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 air. Proper mixing of the air and process streams not only provides high destruction efficiencies but also safe operation with well mixed gas streams. An optional burner system is available to burn inert process streams directly in the burner as fuel.
From a small tank vent to the largest of ethanol plant applications, each Anguil DFTO is designed around our customer’s application. Special designs can be provided to handle process streams that contain acids such as carbonic, hydrochloric or sulfuric acid.
