Modeling of Dust Collection by a High-Temperature Filter with a Phoretically Active Catalyst

The combination of several physical and chemical processes for cleaning flue gas in a single hightemperature filter is a promising technology. The effect of catalytic phoresis on solid-particle collection efficiency is evaluated. A three-level mathematical model describing sedimentation of the catalytic coating on autofilter layers and the filter base layer is presented. Calculation of the filtering of highly dispersed particles with a working catalyst using the proposed model allows the best modes of filtering devices and their design and operating parameters to be chosen.
