Corrosion of silicon carbide hot gas filter candles in gasification environment

Mechanical Characterization of Fiber Ceramics: Effect of Temperature**

“…Figure 2 shows an overview of the grit-blasting apparatus. Tests were conducted in a cabinet (1). A 120°-cut sample (2) was attached to the sample holder (3) by Velcro tape (4).…”

“…In several gas-filtration plants, the fiber ceramics have displaced the more advanced ceramic materials, such as silicon carbide, [1] because of their lower price and capability to form filter elements with lower pressure drop. In several gas-filtration plants, the fiber ceramics have displaced the more advanced ceramic materials, such as silicon carbide, [1] because of their lower price and capability to form filter elements with lower pressure drop.…”

“…Ceramic fibers are used at high temperatures for thermal insulation and gas-solid separation. In several gas-filtration plants, the fiber ceramics have displaced the more advanced ceramic materials, such as silicon carbide, [1] because of their lower price and capability to form filter elements with lower pressure drop. [2] The use of fibers, instead of granular ceramics or metals, [2] in a filter element body is a relatively new approach that needs attention, especially in monitoring their service condition.…”

Corrosion of Ceramic Materials for Allothermal Circulating Fluidized Bed Gasification

“…Dies deutet darauf hin, dass sich das CaMgSiO 4 [14]. Diese aggressive Prozessumgebung bedingt in allen herkömmlichen Filtermaterialien einschließlich der oxydischen und nicht oxydischen Materialien mikrostrukturelle Veränderungen [9].…”

Studies on processing of layered oxide‐bonded porous sic ceramic filter materials

“…Investigations on measurement of mechanical properties , thermal shock resistance, and corrosion resistance of the ceramics are reported and they are conducted mostly for commercial filters. [6][7][8][9][10][11][12][13][14][15] Studies on determination of filtration efficiency and the effects of temperature, dust properties, dust cake formation, cleaning cycles, etc., on the pressure drop of the filters were also carried out. [16][17][18][19][20] Successful operation of commercial filters at severe conditions and at higher temperatures for long duration is still an issue and for this the intrinsic material properties of filters need to be looked in depth.…”
