Thermal afterburning plant in special design
The company Birk supplies a thermal afterburning plant / thermal exhaust air purification plant as a horizontal design to a long-standing customer from the carbon industry. The post-combustion plant / exhaust air purification plant was designed for a raw gas mass flow of 1 kg/h from the exhaust gases of a graphitization furnace plant.
The thermal afterburning plant is equipped with an automatic pressure control in the raw gas feed to ensure constant and stable pressure conditions for the complex and sensitive production processes in the graphitizing furnace. The post-combustion plant was specially designed for this production process and the existing furnace plant. For this purpose, a plant was realized which allows simultaneous processing of the furnace exhaust air (130 mn3/h) from the inlet and outlet zone and the raw/process gases from the furnace chamber - so to speak a small "omnivore". In addition to the furnace pressure control, the plant also has a combustion chamber pressure control, so that it can be adapted to a wide variety of processes. The individual pressure control zones can be operated separately, but also permit simultaneous operation.
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. In addition, special soundproofing measures were implemented to meet the high requirements for soundproofing at the installation site. The thermal afterburning system has been designed to be particularly compact for the required performance data and delivered ready for operation. The plant was designed in such a way that it can be installed by means of a steel platform above the existing furnace plant in order not to consume any further production area. Due to the complete pre-assembly and delivery on the steel console, the assembly time could be reduced to a minimum - which meant only shortest downtimes for the producing furnace plant.
