FF 02 07 04 "Ceramic Filters for Use in Waste Incineration Plants" by Ruedi Frey, Felix Koller and Thomas Hilligardt. BWF Textil GmbH & Co., Offingen, Germany. 4 p.
Based on a patent taken out by BWF, Offingen, the Von Roll Inova company in Zurich started work as far back as several years ago on the development of a process whereby the separation of dust and of nitric oxides would be integrated in one single stage. As a result of the outstanding temperature stability of ceramic filter candles and the similarity of the ceramic fibers to the basic material in catalyzer elements, the concept of the katfilter Pyrotex® KeKat 85 already in use, this now being refurbished with catalytically active substances. This concept combines the advantages of a highly efficient filter medium for the separation of dust with those of a solid state catalyzer for cleaning toxic gas.
