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!
The main reason for the high oxygen content in the coke oven gas entering the processing area may be related to the operation of the coke ovens; if the pressure in the gas collection system is too low, one of the reasons for the large amount of air being drawn in during the pushing of coals is this. Also, check the negative-pressure gas pipeline area for any leaks; leaks can also allow air to enter, resulting in an increase in oxygen content. Measures to adjust the oxygen content in coke oven gas: mainly by adjusting the collector pipe pressure within the specified process range. Any leaking pipes should be fixed promptly.
Focusing efforts on completing coking and coal loading in a short period of time also has an impact on the oxygen content in the gas.
