Cause analysis of furnace brick collapse in naphtha and natural gas conversion furnaces
Thread Content
Dear colleagues in the industry, I would like to ask those who specialize in hydrogen production from naphtha and natural gas to analyze the main reasons behind the collapse of furnace bricks in conversion furnaces. Are there any effective preventive measures?
Too little information has been provided; a simple analysis shows that cracks in the furnace lining allow flue gases to penetrate, leading to dew point corrosion. The insulation nails get corroded and fall off, which in turn causes the furnace bricks to lose their support and fall as well. The sulfur content in the fuel is too high.
