What to do if the oxygen content in coke oven gas is high?

What are the reasons for the high oxygen content in coke oven gas in the inlet zone? How to solve it? Please give me some advice!
(1) Check the operation of the coke oven: either the rise pipe is kept open for too long, or high-pressure ammonia water is used for an extended period. (2) The gas pipelines and equipment in front of the machine are not properly sealed, especially after maintenance when sealing can be poor. (3) It is that the measuring instrument is faulty. In systems that use steam injection, excessive oxygen content can occur if the steam contains moisture or if the pressure is unstable. (4) If a person is used for sampling, it is possible that they do not stay long enough, resulting in inaccurate samples.
