根据华润电力首阳山有限公司2×600MW超临界机组的运行特性及在运行中出现的一些问题,特别是由于缺乏超临界直流锅炉的运行经验,难于掌握直流方式运行的动态特性,难于从循环方式运行向直流方式转变。对这些问题进行分析探讨和总结经验,为以后大型超临界机组的调试及运行提供安全、稳定的条件。 According to the operating characteristics of 2 × 600MW supercritical units of China Resources First Yangshan Co., Ltd. and some problems in operation, especially due to the lack of operating experience of supercritical once-through boilers, it is difficult to grasp the dynamic characteristics of DC mode operation and it is difficult to recover from the cycle Mode of operation to DC mode change. Analysis and discussion of these issues and lessons learned for the future commissioning and operation of large-scale supercritical units to provide safe and stable conditions.
