Abstract
We have developed a new exhaust-gas treatment system using ceramic filters with a sodium react ant that removes particulates and acid gases in the temperature range of 300℃. This system has been applied to a kiln-type pyrolysis gas melting plant for MSW (70t/24h x 2 units),As the heat source for the pyrolysis, this plant uses the exhaust from burning the combustible gas generated by the pyrolysis process. This new filtration system lias been applied to this exhaust gas at the temperature range of 300℃ for the removal of the particulates and acid gases. The filter element is made of sintered materials (produced by Kyocera Co.) and is stronger than thosemade of fabrics.This plant began an operation with load in June of 2005. The pressure loss of ceramic filter is approximately 3.0 kPa at the filtration, speed of 1.4 m/min, approximately 7 years after startup, and the operation has been continuing in a stabilized manner. Also, used filter is renewable by washing, so the filter can be, used for long period
