摘要
介绍了某厂630 MW亚临界锅炉长程吹灰器控制系统在实际运行中存在的典型问题,并对吹灰器控制逻辑进行优化设计,在不进行现场硬件回路改造的前提下,通过逻辑判断实现了吹灰枪启动失败、中途故障停运以及运行超时等异常工况的识别报警,有效保障了锅炉吹灰的安全进行。
This paper introduces the typical problems existing in the operation of the long-range sootblower control system of a 630 MW subcritical boiler in ninghai power plant.Through the optimization design of the sootblower control logic,the fault identification and alarm of the abnormal working conditions such as the start failure of the sootblower,the shutdown of the midway fault and the operation timeout are realized by logical judgment without the transformation of the field hardware circuit,which effectively guarantees the safety of the boiler.
