Operation And Maintenance Manual For Fabric Filters

Gas flow through shaker-type fabric filters is usually limited to a low superficial velocity or A/C ratio of less than 3 ft/min and a typical range of from 1 to 2 ft/min. High A/C values can lead to excessive particle pene- tration or blinding, which reduces fabric life and results in high pressure drop.

Stabilization of stainless steel slag via air granulation

In stainless steel production, slag from argon oxygen decarburization (AOD) converters is dumped on to the ground and then slowly cooled. The slag undergoes phase transformation from β-dicalcium silicate (β-C2S) to γ-dicalcium silicate (γ-C2S) at approximately 500 °C to 450 °C, resulting in slag volume expansion, disintegration, and dust ...
