Abstract：

The ceramic filter element in fly ash filter frequently broke in the process of dry-type dust collection.To resolve this problem,taking the fly ash fliter installed in Shenhua coal to liquid facility as research object,developed a new type filter element which is made of Fe3Al.The characteristics of this advanced material was tested by analysing properties of synthesis gas and fly ash,collection efficiency,differential pressure flow curve,filter cake porosity.The results show that,the filter element can stabilize the differential pressure at 20 kPa while the processing capacity is 3×105 m3/h.The Fe3Al filter element has good resistance from H2S corrosion.Even if its surface is slightly corroded,the thickness of corrosion products(FeS) is 0.5 μm,so it can stably run in the gasification devices.
