Raw material gas filter before the converter
Thread Content
Those who know it, please share information on the selection, manufacturers, and usage of the raw material gas filters in converter furnaces.
Never used, just waiting. . . .
You are referring to the pre-conversion before the transformation; it depends on the gasification process being used. However, using it is definitely better than not using it at all. Usually, two such systems are used in parallel to facilitate maintenance, and those used for pre-conversion are either waste catalysts or catalysts with lower activity.
A protection bed, which is generally filled with alumina ceramic balls, serves to further remove dust from the gasified gas.
