How to check for leaks in coke oven gas transmission pipelines?
Thread Content
As the title suggests, I would like to know what methods are primarily used by various factories to detect gas leaks in the negative-pressure and positive-pressure sections of their coke oven gas transmission pipelines
Gas leak detector； Coke oven gas leak detector ； Blast furnace gas leak detector. Gas companies provide them, they come with alarms and are very useful!
1. Monitor the oxygen content in the gas online to determine whether air is entering the negative pressure section； 2. In the positive pressure section, a CO alarm is used to detect any gas leaks.
GB12710-2008 stipulates that an alarm should be triggered when the oxygen content in the gas exceeds 1%, and the electrostatic tar catcher should shut down automatically when it exceeds 2%. There will be no problem as long as the oxygen content does not exceed the limit.
Inspection: valves, flanges, drain pipes, manholes, welds
