What is the black substance inside the drum?
Thread Content
In the conversion drum in my workshop, when checking its interior, I found black substances below the liquid level; some of this was rust powder. I’m not sure what those black substances are I would like to ask the expert for some guidance. Thank you!
It might be due to improper water quality control; there could be corrosion in the steam drum
