What does it mean when gasification produces hair-like or cotton-like residues?
Thread Content
Dear sea friends: Recently, slag from the gasification furnace has taken on shapes different from those seen before; one type is short, hair-like slag, and it is black in color； There is also a type that is cotton-like in texture and very light. I don’t know what the situation is? We burn hazardous waste, including activated carbon, DMF residues, wastewater from pharmaceutical factories, and coal. Recently, due to faults at the temperature measurement points in the gasification furnace and overheating of the large flange above the quench ring, the oxygen-to-feed ratio has been kept at around 455. Have any sea friends encountered it?
There is a paper you can refer to: \"A Brief Discussion on the Relationship between Slag Samples and Gasification Furnaces\"
