Abstract:

When coke oven couldn’t keep normal production, normally the method of extending coking time was adopted to lower production capacity. The work of oven temperature adjustment and control, pressure adjustment and control, oven proper maintenance were well done in case of longer coking time. The control measure and experience under the condition of long coking time of coke oven were analyzed, the process indexes such as Kmean, Ksafe and coking heat consumption and oven chamber vertical heating were proposed.
