Abstract Ceramic filter is generally used to remove particulate matters in hot flue gas. The granule typed ceramic filters made of SiC powders were prepared and their filtration characteristics were investigated with a single collector efficiency model in this study. We found that diffusion was a dominant collection mechanism for particles smaller than 0.7 µm, and direct interception and inertia were dominant collection mechanisms for particles lager than 0.7 µm in a granular ceramic filter based on the model. In addition, filter performance factor, qFM considering physical strength, collection efficiency and pressure drop was introduced to evaluate the ceramic filter properties, and SiC50 filter was the best in ceramic filters fabricated in this study.
