Blockage in the tertiary condensate drainage pipeline
Thread Content
The third-stage condensate drainage pipeline gets clogged frequently – help!
Is it blocked by sulfur? Check whether the temperature of the jacket heating can be achieved ； Check again to see if there is a leak in the jacket heating ；
Bring in the purified water and add a backwash line; we’ve encountered this issue as well, and the heat tracing doesn’t work properly either
It is likely that ammonium salts have caused the blockage. As an emergency measure, backwashing with purified water or deoxygenated water should be carried out. The root cause lies in the operation of the sulfur production furnace or the burner; mainly, the ammonia does not burn completely, and as a result, ammonia ends up in the subsequent systems.
Is the heat tracing return pipeline too high?
I agree with you. . . It is also possible that carbon deposits accumulated at the stopcock and the jacket tee are causing poor sulfur discharge.
