Anguil - Model DFTO - Direct Fired Thermal Oxidizer
The Anguil Direct Fired Thermal Oxidizer (DFTO) destroys Hazardous Air Pollutants (HAPs) and Volatile Organic Compounds (VOCs) that are discharged from industrial or chemical process exhausts. The DFTO achieves destruction of pollutants by the process of combustion. VOCs and HAPs are oxidized to carbon dioxide and water vapor with the proper combination of temperature, residence time and turbulence within the combustion chamber. The DFTO is an ideal abatement technology for process streams heavily laden with pollutants and intermittent batch processes where the oxidizer can come on-line relatively quickly.
Sometimes referred to as an Afterburner, Enclosed Flare or Vapor Combustor 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.
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.
