Incineration processes for the industry

Incineration processes for industrial exhaust air purification

Incineration processes are central to industrial exhaust air purification and are used wherever VOC-contaminated or alternating exhaust air needs to be treated safely. Especially in surface technology - for example in the wood and furniture industry, automotive industry, aviation, building materials, construction elements, glass, plastics and metals processing - it ensures stable purification levels and reliable process conditions.

With VEN CLEAN AIR, Venjakob offers flexible afterburning systems that can be optimally adapted to industry-specific requirements.

Frequently asked questions about post-combustion

In demanding production environments, the selection and design of the appropriate post-combustion process plays a central role. The following questions provide orientation for safe and efficient exhaust air purification.

We will be happy to advise you

How does the composition of the exhaust air influence the choice of processes?

VOC type, particle content, temperature and humidity determine the temperature window, catalyst selection and system layout.

What role does heat recovery play in economic efficiency?

A high degree of heat recovery significantly reduces operating costs and can make thermal processes almost energy self-sufficient.

How are load fluctuations reliably equalised?

Modern control systems dynamically adapt temperature, flow and valve routing to changing volume flows.

What are the requirements for integration into existing plant lines?

Interfaces to conveyor, coating and drying modules as well as flexible communication protocols are crucial.

How is compliance with legal VOC limits documented?

Via continuous temperature and process data recording with audit-proof storage.

The Venjakob process chain

Dry coating technology

Efficient drying and curing systems ensure short process times and consistent results. Depending on the coat or adhesive system, convection, infrared, UV or combined drying processes are used.

Exhaust air purification

Venjakob exhaust air systems clean process air reliably and energy-efficiently. Cyclone, filter or thermal systems safely remove pollutants and enable recirculated air operation - for environmentally friendly and economical production.

Industrial robotics

Robot-based systems perform precise application and handling tasks. They increase flexibility in production, ensure reproducible motion sequences and enable automated process adjustments.

Process monitoring

Intelligent control and visualisation systems network all system components. They enable transparent process monitoring, simple operation and integration into higher-level production systems.

Material handling | Conveyor technology

Precise conveyor technology ensures that workpieces are transported safely and evenly through all process steps. Modular systems ensure flexible adaptation to different production environments.

Surface pretreatment

Clean and activated surfaces are the basis for optimum coating results. Depending on the material, cleaning, degreasing or activation processes are used - precisely tailored to the subsequent process.

Industrial finishing | Coating

Venjakob systems enable reproducible coating results with maximum material efficiency. Different application systems ensure uniform coating thicknesses and the highest surface quality.
