Catalytic bag-house filters

Composite nonwovens in filters: applications

“…In applications such as incinerators, pyrometallurgical and cement kilns, the combination of surface fi ltration and catalysis (ALSOM Power, 2008) has created new methodologies which destroy gaseous dioxins and captures solid phase emissions, leading to operational cost savings. Effi cient particle, NO x and VOC removal can be achieved via the use of fabric fi lters or ceramic hot gas fi lter elements (foam candles) which combine a fi ne fi ltering outer membrane with an integrated catalyst in the support structure (Spivey, 1993;Bonte et al , 2002;Hackel et al , 2005;Nacken et al , 2007;ALSOM Power, 2008;Heidenreich et al , 2008). The combination of a fi lter and an SCR (selective catalytic reduction) reactor in one unit ( Fig.…”
