What causes blockage in the sulfur recovery oxygen burner?
Thread Content
Our company’s sulfur recovery unit has been in operation for 7 years, and the burners have never been clogged. Last year, after a blockage occurred, oxygen could no longer be supplied. During a major maintenance session, the burners were inspected and it was found that scale had caused the blockage; after cleaning them, they became clogged again within less than a month of being put back into use. I would like to ask experts what could be the reason for this. Also, may I know what is the WeChat group for technical exchanges on sulfur recovery in our forum? Want to join the group
Could it be caused by too low oxygen pressure? HaiChuan only has a WeChat official account called “HaiChuan Chemical Forum”“
Is it an oxygen-enriched burner? What is the blockage? Sulfur? What are the operating pressures for acid gas and oxygen? Based on your description, it seems that low oxygen pressure is causing sulfur to clog the nozzle
Yes, the blockage is something like scale – it’s hard, not sulfur. The pressure of the acidic gas is between 0.13 and 0.14, while the oxygen pressure is between 0.27 and 0.28. Master, what do you think is causing this?
Hello, how is the result after processing?
I’ve learned it, thank you so much! ! !
