What factors are associated with a high oxygen content? No issues were found in the negative pressure area
Apart from the negative pressure area, it may also be related to the blower inlet, the size of the air space for coal charging in the coke oven, and the coal itself.
It is possible to check whether the workers are following proper procedures when using high-pressure ammonia solutions, as this could lead to an excessive oxygen content. Recently, our company has reduced production, resulting in less gas supply and an excessively high oxygen content.
In addition to what the others have said, you can also check the desulfurization liquid level regulator; if it isn’t functioning properly, air will be drawn in, increasing the oxygen content
In my opinion, if the coking time is extended without promptly increasing the pressure in the gas collection duct, air will be drawn in due to the negative pressure inside the furnace. It may also increase the oxygen content in the gas. I’m not sure if it is
We took samples from the two gas collection pipes for analysis; the oxygen content was above 1.4, with a maximum of 2.6. The pressure in the gas collection pipes was set at 100
In the case of ramming coking, abnormal coal charging, especially prolonged use of high-pressure ammonia by the smoke guiding vehicle, can lead to an excessive oxygen content in the gas; it is appropriate to start by investigating the coking process first.
This phenomenon occurs when the coking time is long during production restrictions.
