摘要：

The present research investigates the removal of particulate matter smaller than 2.5 mu m (PM2.5) from high-temperature exhaust gas using a twin ceramic candle filter. Computational fluid dynamics (CFD) is used to simulate gas flow behavior since the technique could provide crucial support to experimental investigation, especially for harmful conditions, as well as yield cost savings and fast results. In this research, the dynamic behavior of gas flow in a prototype twin-candles ceramic filter was studied. One interesting phenomenon not seen in single candle filtration systems is the unforeseen cleaning effect on an adjacent candle filter due to the pulsed cleaning of another. It is useful to investigate the face velocity distribution on the candle as it illustrates how the filter cake is formed on the filter surface and hence leads to improvement in the dust cleaning. The obtained simulation results were validated with available experimental data. (C) 2007 Elsevier B.V. All rights reserved.
