Large-format thermal post-combustion in the Conti furnace
The company Birk supplies a thermal afterburner / thermal exhaust gas purification to a long-standing customer from the automotive supplier industry. The afterburner/exhaust gas cleaning system was designed for a raw gas mass flow of approx. 75 kg/h from the exhaust gases of a carbonation process.
The system has a special design of the raw gas inlet in order to meet the limited space conditions of the customer at the installation site, to guarantee the high static pressure stability required by the process and at the same time to minimize the maintenance and cleaning cycles of this system component.
In order to meet the high customer 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 noise emission reduction requirements, 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 plant is designed as a compact version, whereby it was delivered almost ready for operation, i.e. electrically and mechanically pre-installed, so that the entire installation including the commissioning for production readiness of this "large plant", with simultaneous dismantling of the old plant, could be realized in a small time window of only 11 working days. All 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.
