Thermal exhaust air cleaning for critical processes
Birk supplies a thermal afterburner / thermal flue gas cleaning system as general contractor to a globally operating specialist for copper and copper alloys.
Post-combustion/flue gas cleaning was designed for a raw gas mass flow of 55 mn³/h - specially adjusted to the calorific value of the raw gas components included therein according to the material data - from the flue gases of upstream process and production plants. The plant has an ingenious arrangement of the numerous plant components in order to meet the limited space conditions in the customer's complex on-site platform system at the installation site.
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. The plant has a corrosion-resistant design of the reaction chamber housing and full-surface external insulation in the entire area of the combustion chamber jacket to ensure a long service life even with critical exhaust air components.
The external insulation is designed as a completely closed, smooth and coloured sheet metal and, in addition to its protective function, gives the system an elegant appearance. In order to meet the equally high requirements for noise emission reduction, the afterburning system is equipped with a comprehensive package of measures for noise reduction. The entire scope of supply also included parts of the raw gas supply/exhaust into the combustion chamber, the exhaust air conveyance as well as parts of the clean gas discharge with noise reduction. The plant is designed as a compact unit, whereby 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 S7 control, which is equipped with a user-friendly visualization with touch function.
