The Anguil Direct Fired Thermal Oxidizer (DFTO) destroys
Hazardous Air Pollutants (HAPs) and Volatile Organic Compounds
(VOCs) that are discharged in industrial or chemical process
exhausts. The DFTO achieves destruction of pollutants by the
process of combustion. The 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 technology for process streams heavily laden with
pollutants and intermittent batch processes where the oxidizer can
come on-line relatively quickly.
How the Direct Fired Thermal Oxidizer Works
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.
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.
