Direct Fired Thermal Oxidizers | High-Efficiency VOC & Emissions Control
Epcon Industrial Systems is a recognized leader in Direct Fired Thermal Oxidizer (DFTO) technology, offering custom-engineered, modular, and trailer-mounted solutions for industrial emissions control. With decades of expertise in thermal process applications, we design and manufacture high-performance DFTO systems that meet stringent environmental and operational requirements.
Direct Fired Thermal Oxidizers, also known as Afterburners or Direct Flame Thermal Oxidizers, are one of the most effective methods for destroying volatile organic compounds (VOCs) and hazardous air pollutants (HAPs). These systems are particularly well-suited for high-solvent loading applications and fluctuating process conditions, providing maximum destruction efficiency (DRE) and reliable performance in demanding industrial environments.
How Direct Fired Thermal Oxidizers Work
DFTOs operate by exposing process exhaust gases to high temperatures ranging from 1250°F to 1800°F, with gas residence times of one second or less. Under these conditions, the molecular structure of the process stream is completely broken down, converting harmful pollutants into carbon dioxide and water vapor.
Proper sizing and configuration are critical to system performance. Epcon’s engineering team carefully evaluates process stream composition, temperature, and flow characteristics to ensure optimal design. Epcon’s engineering and design services ensure each DFTO system is tailored for optimal performance based on process stream data. Flame arrestors, burner placement, and air-to-fuel ratio control are precisely integrated to maximize efficiency while maintaining safe and stable combustion.
DFTOs are especially effective in midstream oil and gas applications where emissions control is critical under fluctuating conditions.
