Robust high-temperature oxidation for demanding exhaust air streams

When Exhaust Air Streams Become Challenging

Thermal incineration is required when VOC-laden exhaust air must be safely treated—even under demanding or fluctuating process conditions. The processes operate at high temperatures and oxidize organic compounds directly in the combustion chamber. Compared to catalytic incineration, it is less dependent on an exact match in exhaust gas composition; compared to Regenerative thermal incineration, the focus is not on maximum heat recovery but on robust high-temperature oxidation. Key design factors include temperature, residence time, and uniform mixing of the exhaust air. As a result, TNV is particularly well-suited for processes where safety, process stability, and reliable emission levels are critical.

VEN CLEANAIR TNV Thermal Incineration Systems

Designed from the combustion chamber to the process integration

VEN CLEANAIR TNV systems are not considered in isolation but are planned to fit the production environment. In addition to the combustion chamber and burner technology, the design also includes media supply, safety concepts, system control, maintenance access, and integration into existing exhaust air systems. The result is a TNV solution that is technically compatible with the process and practically suited to operations.

The Benefits of Thermal Incineration

Thermal incineration is the robust solution for VOC-laden exhaust air streams where real-world conditions don't follow the textbook: varying components, fluctuating concentrations, or challenging process conditions.

Reliable in the presence of fluctuating VOCs

Even if ingredients or concentrations change, TNV remains a reliable solution. It is less sensitive to fluctuations than catalytic processes.

No dependence on the catalytic converter

Since oxidation occurs purely through thermal processes, catalyst poisons or substances incompatible with catalysts do not play a significant role. This expands the range of applications for more complex exhaust air streams.

Safe oxidation in the combustion chamber

Temperature, retention time, and mixing are designed to ensure that organic components are reliably converted. This is particularly important when strict requirements for stable emission levels must be met.

Suitable for demanding processes

TNV is also a viable option in situations where load cycles, higher temperatures, changing formulations, or special safety requirements rule out a simple, standard solution.

Clear process control

The cleaning process can be monitored and controlled using defined operating parameters. This provides transparency for operators, maintenance personnel, and regulatory compliance.

Supplementary Exhaust Air Purification Processes

Exhaust air systems can be enhanced through adsorption, concentration, and energy recovery. These supplementary processes improve efficiency in certain exhaust air situations and support energy-optimized system operation.

Adsorption and Concentration

Zeolite rotors are used for concentration; they adsorb VOCs from large, low-concentration exhaust air streams. The concentrated exhaust air is then thermally oxidized, which reduces the energy requirements of the main process and improves system efficiency.

Energy Recovery in Exhaust Air Systems

Thermal energy can be recovered from purified exhaust air using heat exchangers or regenerative storage systems. This heat can be used in dryers, for process air, or for heating the facility, significantly reducing overall energy consumption.

An Overview of the Incineration Processes

After-combustion processes reliably oxidize VOCs into CO₂ and water. Depending on the exhaust air stream(s), load, and energy requirements, three established processes are used. The following overview helps simplify the selection process for applications such as coating, drying, and adhesive application.
