The iron issue in slag
Thread Content
It has been suggested that using coal BGL slag for gasification in cases where the ash melting point is high may lead to poor slag discharge after iron is melted. Could anyone tell me what the reason for this is? Doesn’t the slag resulting from slag gasification necessarily have to be molten?
I also want to know whether severe iron precipitation has occurred during the operation of our Shell furnaces as well
In a reducing environment, iron in coal ash can precipitate as iron oxides; therefore, the iron content in coal ash is generally kept below 15%, and it is preferable to have it below 10%

It has nothing to do with the operation; it’s related to coal ash
