Thermal afterburning for 30kg/h with NOx reduction
The company Birk supplies a thermal afterburning plant / thermal exhaust air purification plant in customized special execution to a customer of many years from the high temperature industry furnace construction.
The post-combustion plant / exhaust air purification plant was designed for a raw gas mass flow of 30 kg/h from the exhaust gases of an upstream special heat treatment plant. The plant has a special design of the raw gas inlet as well as a customer-specific arrangement of the other plant components in order to meet the limited space conditions at the installation site. The exhaust gas cleaning system is designed in such a way that, in addition to the thermal conversion of the supplied raw gas, pollutant-laden waste water (e.g. HCN) can be post-combusted at the same time.
In order to be able to maintain the clean gas values with regard to nitrogen oxide formation during different pre-process phases with high nitrogen content in the raw gas, the post-combustion plant is already prepared for the subsequent installation of an SNCR plant (urea injection). The system has full-surface external insulation in the entire area of the combustion chamber jacket to prevent condensate formation in the reaction chamber and reduce the surface temperature. This is designed as a smooth, lacquered sheet metal jacket and, in addition to its protective function, gives the system an elegant appearance.
The system is controlled and operated via the in-house PLC S7-based control system with touch display. The system is designed as a compact version, which means that it is delivered ready for operation, i.e. completely electrically and mechanically installed. The system is designed for export and has multilingual documentation and visualisation.
