Abstract:

The harm of CO as well as the factors effected CO content in waste gas by coke oven heating is summarized.CO content in coke oven waste gas can be reduced efficiently by technical measures such as controlling excess air factors,bettering bricklaying management of newly-built coke oven,using reversing cocks during BFG heating,adding air cleaning device during reversing,installing on\|line instruments to detect the content of the waste gas,and emphasizing routine hot maintenance for coke oven.
