Direct Thermal Oxidizers

Direct thermal oxidizers, sometimes referred to as afterburners, utilize direct combustion to convert volatile organic compounds in gaseous effluents to carbon dioxide and water. EnviroAir custom designs each system, considering such important design principles as proper combustion chamber mixing, sufficiently high temperatures, and adequate time for the combustion process. Additionally, the orientation of the oxidizer can be changed to suit the customers space constraints.

Typical Operation of Thermal Oxidizers

Typical direct fired thermal oxidizers are shown here. The forced draft fan draws in process air and discharges it to the thermal oxidizer. In the thermal oxidizer, the process air is heated to the design set point temperature by the burner. Turbulence is created as the air passes by the burner and into the combustion chamber to ensure proper mixing. The combustion chamber is sized to provide the residence time required to destroy the hydrocarbons in the air. The clean hot air then flows up the stack to the atmosphere.
