Recuperative Thermal Oxidizers for Cost-Effective VOC Destruction
Recuperative thermal oxidizers provide reliable, economical destruction of Volatile Organic Compounds (VOCs) through high-temperature oxidation combined with efficient heat recovery. By using an integral shell-and-tube heat exchanger to preheat incoming contaminated air, recuperative oxidizers recover up to 70% of the heat generated during the oxidation process, significantly reducing fuel consumption and operating costs.
Recuperative oxidizers convert VOCs to carbon dioxide and water vapor at temperatures typically above 750°C (1,382°F), providing destruction efficiencies of 95-99% while maintaining cost-effective operation through integrated heat recovery.
How Recuperative Thermal Oxidizers Work
EIS recuperative thermal oxidizers use a straightforward, proven design that combines thermal destruction with efficient heat recovery.
Air Preheating
Contaminated process air enters the recuperative oxidizer and passes through a primary shell-and-tube heat exchanger. Here, the incoming air is preheated by the hot, cleaned exhaust gases leaving the combustion chamber—recovering up to 70% of the system’s thermal energy.
Heat Recovery
The high-temperature cleaned exhaust gases pass through the primary heat exchanger, transferring their heat to the incoming process air. Optional secondary heat exchangers can capture additional heat for use in other facility processes such as space heating, process heating or makeup air preheating.
Thermal Oxidation
The preheated air enters the combustion chamber where it is heated to temperatures above 750°C (1,382°F) by a burner system. At this temperature, VOCs are thermally oxidized (destroyed) and converted to carbon dioxide and water vapor. When VOC concentrations are significant, the heat released during oxidation supplements the burner, further reducing fuel consumption.
Clean Air Discharge
After heat recovery, the cooled, cleaned air is safely discharged to atmosphere through a stack, meeting all emission requirements.
