How to remove carbon deposition in the tube bundle of the waste heat boiler in Claus furnaces
Thread Content
The waste heat boiler tube bank in the Klaus furnace has accumulated carbon deposits, resulting in high resistance. How can these deposits be removed? Please advise!
If carbon buildup does occur, there’s no good solution other than shutting down operations. Is the temperature behind the furnace high?
Stop, wash with high-pressure water; forget about it – that’s all there is to do
Carbon deposition is caused by the presence of hydrocarbons in the feed gas, but it is generally kept at very low levels; we control it here
240 degrees behind the furnace – can introducing some steam help reduce carbon?
The temperature behind the furnace isn’t high, so the heat exchange efficiency is excellent.
