Build a new heating furnace
Thread Content
How can the slag and impurities inside the furnace tubes of a newly installed regenerative heating furnace be removed? Thank you!
Wind purge, medium-pressure steam, high-pressure purge!
Is there no other way? Can it blow out relatively heavy impurities?
Steam purging. Remember to blow from the higher position to the lower one.
Using steam for cleaning is fine; at present, steam cleaning is the most effective method. There’s not much that can be done about the impurities in the U-shaped bend of the furnace tube; if the steam can’t carry them away, it’s not a problem, as the oil entering won’t bring those impurities along as well.
Fear to carry out blasting, as the resulting vibrations could damage the furnace walls and the furnace tubes
Anything can be inside the furnace tube in gloves
