Cupola Furnaces / Furnace Gas / Casting ProcessesEfficient Solutions for All Processes


In addition to molten metal, cupola furnaces also generate a lean gas stream that is contaminated with condensable organic compounds and dust. The exhaust gases, which evolve during the subsequent thermal afterburning, are very corrosive due to sulfur compounds. Dust particles quickly affect heat exchangers. Therefore it is necessary to design them extremely large and with elaborate cleaning systems. This strongly impairs the reliability of the process.

With the hot gas filters HF Pulse or CPP High Force and the Turbox Dry Sorbent Injection, Calida Cleantech offers technical solutions to enable efficient and economic gas processing for different approaches. The process is being optimized by downstream equipment that efficiently separates dusts even prior to the thermal afterburning.
