Abstract

Correct hydraulic parameters are required for safe long-term operation of coke batteries. Maintaining positive pressure in the ovens throughout coking preserves the lining of the coke oven, because air leakage into the chamber is prevented. The chronological development of concepts regarding coke-oven hydrodynamics is reviewed and, on that basis, low pressure in the coke ovens is shown to appear only in the case of lining defects or incorrect measurements. Therefore, the pressure in the gas lines of the coke battery should be considerably less than that currently employed, so as to decrease the leakage of raw coke-oven gas into the heating system. Such decrease in gas pressure in the coke ovens decreases the consumption of coke-oven gas in heating, without loss of coke quality. To maintain the lining of each coke battery, hot repair must be employed: for example, ceramic surfacing or welding; the application of special ceramic coatings; and stopping of cracks and seams by insertion of ceramic. In addition, by sealing cracks and seams with ceramic, the expansion of the lining may be slowed, with corresponding extension of battery life.

焦炉的水力分析

摘要

为了使焦炭电池长期安全运行，需要正确的液压参数。在整个焦化过程中，保持炉内的正压可保留焦炉的内衬，因为可防止空气泄漏到炉膛中。回顾了有关焦炉流体力学原理的时间顺序发展，在此基础上，显示出仅在炉衬缺陷或测量不正确的情况下，焦炉中的低压才会出现。因此，焦炭电池组的气体管线中的压力应大大低于目前使用的压力，以减少原料焦炉煤气泄漏到加热系统中。焦炉中气压的这种降低减少了加热中焦炉气的消耗，而不会损失焦炭质量。为了保持每个焦炭电池的衬里，必须进行热修复：例如，陶瓷表面处理或焊接；特殊陶瓷涂料的应用；并通过插入陶瓷来阻止裂缝和接缝。此外，通过用陶瓷密封裂缝和接缝，可以减缓衬里的膨胀，并相应延长电池寿命。
