초록
In this study, the porous ceramic filter was developed to be able to remove both dust and hazardous gascontained in fuel gas at high temperature. The porous ceramic filters were fabricated and used as a catalyst support. And the effects have been investigated such as the mean particle size, organic content and addition of foaming agent onthe porosity, compressive strength and pressure drop of ceramic filters. With the increase of mean powder size and theorganic content for the cordierite filter, the porosity was increased, but the compressive strength and pressure drop weredecreased. From the results of the research, the optimum condition for the fabrication of ceramic filters could beacquired and they had the porosity of 58%, the compressive strength of 13.4 MPa and the pressure drop of 250 Pa. Itwas expected that this ceramic filter was able to be applied to the glass melting furnace, combustor, and dust/toxic gasremoval filter.
