The TO furnace collapsed near the burner
Thread Content
This is an exhaust gas combustion furnace that burns exhaust gases using natural gas as a supplementary fuel to meet emission standards. At the top, there should be firebrick and fireproof mortar secured with insulation nails. Upon entering the manhole, it was found that the fireproof bricks had collapsed and the pipelines were carbonized. This is a casting material. What’s the reason? Is it too high a temperature? Is the furnace heating curve still poor? What else is the reason?
The firebrick casting is conductive to heat; the insulation nails used for fixation get damaged, resulting in collapse
It’s likely that the lining and insulation nails here were not installed properly
Check the stability of the furnace at that time; the temperature controlled by the TO system should be below 1100 degrees Celsius. The outer flame in the combustion chamber may be too hot, and for this purpose, mullite-based high-temperature cast materials should be used for the refractory materials, while 310S material should be used for the anchoring elements
