焦炉长结焦时间状态下的管理与维护

Management and maintenance of coke oven under longer coking time

在焦炉不能维持正常生产时,一般采用延长结焦时间的方法降低生产能力。介绍了焦炉在长结焦时间状态下,从规范出炉操作入手,做好炉温调控、压力调控、炉体维护等工作。分析了焦炉长结焦时间状态下的控制措施与控制经验,对K均、K安、炼焦耗热量等工艺指标及炭化室高向加热等问题提出了建议。

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.
