Sintered Fe₃Al Intermetallic - A New Filter Element for Hot Gas Filtration

Abstract:

Hot gas filtration and purification is widely applied in many industrial fields, such as in power generation industry, chemical and petrochemical industry, metallurgical industry, ceramic and glass industry, environmental protection industry, etc. Gas filtration at high temperature from industrial processes offers various advantages such as increasing process efficiency, improving heat recovery and materials resource recovery, protection of downstream plant equipment, etc. At the same time, it is an advanced environment protection technology. This paper describes a newly developed metallic filter element - sintered Fe3Al intermetallics. The manufacturing process of sintered Fe3Al metallic powder and the mechanical and filtration characteristics of this filter element were investigated. In this work, the mechanism of the morphological and phase constituent changes of the Fe3Al powder during sintering were studied. The newly developed filter elements were found to have excellent corrosion resistance, good thermal resistance, high strength and high filtration efficiency. Based on these results, the potential application of the sintered Fe3Al filter elements in industrial hot gas filtration are discussed.
