Refractory repair for gasification furnace
Thread Content
The current refractory material used in the gasification furnace is castable, but it is not cast as a single piece; gaps were found between the refractory materials at some joints, resulting in overheating of the outer wall of the gasification furnace. However, due to location and space constraints within the gasifier, the gaps between the refractory materials at the aforementioned joints cannot be repaired manually. I wonder if anyone has any good suggestions?
Your issue requires re-instruction from the expert; before starting the work again, it is necessary to accurately calculate the amount of expansion of the casting material and leave appropriate expansion joints.
What do you mean by carrying out direct manual repair? Could you explain it in more detail? Generally, problems with the gaps between the bricks in a gasification furnace cause the furnace wall temperature to exceed the designed level; in such cases, the only solution is to replace the bricks on the side facing the flame. There is no other way at present.
Are you referring to the silicon carbide coating on the water wall of the SHELL gasifier?
"Direct manual repair” refers to filling the damaged area with casting material.
Has the original poster heard of this conservative treatment method called self-flowing material? I don’t think it exists; it seems to involve using a paste-like, heavy material with a high water content to fill the cracks. :loveliness: :loveliness: :loveliness:
I agree that we should rebuild the furnace now, and redo the several bricks with gaps
Repairing it directly with repair material still yields good results
