Thermal afterburning at the Conti furnace

The company Birk supplies a thermal afterburner / thermal exhaust gas purification as a subcontractor via a renowned industrial furnace manufacturer to a long-standing customer from the automotive supplier industry. The post-combustion/exhaust gas purification system was designed for a raw gas mass flow of 40 kg/h from the exhaust gases of a carbonation process.

The plant is equipped with a special design of the raw gas inlet in order to meet the limited space conditions of the customer at the installation site. In order to meet the customer's high requirements for operational safety and plant availability, numerous plant components are designed according to the high standards of the SIL classification, which guarantees a high level of protection for the employees as well as a high level of process stability.

In order to meet the equally high requirements for noise emission reduction, the afterburning system is equipped with a comprehensive noise reduction package, which also includes the 2nd generation low-dB sound insulation cabins on the fans. These measures guarantee a total noise emission of less than 65 dB at the thermal afterburning system.

The system is equipped with full-surface contact protection in the entire area of the combustion chamber jacket. This is made of perforated sheet metal and, in addition to its protective function, gives the system an elegant appearance. The entire scope of supply also included the raw gas supply/exhaust with bypass function, a platform construction for placing the TNV plant with walkways above the kiln plant, as well as the clean gas discharge by means of an industrial chimney system.

The system is designed as a compact version, which means that it is delivered ready for operation, i.e. electrically and mechanically pre-installed. The entire control, regulation and monitoring functions of the plant are performed by a Siemens fail-safe S7F control, which is equipped with a user-friendly visualization with touch function.
