ABSTRACT
Advanced cyclone, cross flow filter, granular bed filter, electrostatic precipitator, and candle filter have been developed for particulate matters collection on the advanced coal power generation system. Ceramic rigid filters and granular bed filter among them have the best potential. A ceramic candle filtration system has been operated under the high temperature in order to obtain the design data for a pilot unit of integrated gasification combined cycle(IGCC) and high temperature gas cleanup facility. Three candle elements of 1 m length were mounted on the tube sheet by using the specially designed filter holder. The compressed air was used for the stream gas carrying dust injected from a screw feeder and heated by an electrical heating unit. The compatibility of the filtration system involving element mounting technology was checked. Some operation results were obtained. The behaviour of the pressure drop, the pulse cleaning events, and the durability of the filter element were investigated in this study.
