What are the reasons for scarring on the surface of the first layer of the converter?
When parking, sulfur dioxide is not completely removed; upon returning to room temperature, it turns into sulfurous acid, which then reacts with the impurities on the surface of the catalyst
The drying effect is poor, and the moisture content in the furnace gas is above the standard.
Excessive moisture and acid mist, high dust content in the flue gas, etc
The drying effect is poor, with frequent start-ups and shutdowns; if it is used for acid production through smelting, the F level may exceed the limit
In the case of sulfur-based acid production, the ash content in liquid sulfur is above the standard.
Mineral dust can clog equipment and cover the catalyst surface, causing scarring on it.
An element analysis can be performed to determine the specific cause
