华润电力常熟第二发电厂1号650 MW汽轮发电机组,含国产首台1952.21 t/h超临界复合循环锅炉。该直流锅炉有不同于汽包炉的调试过程,如投粉稳压冲管、系统的启动、安全门的整定、锅炉燃烧的初调整及低负荷稳燃的调试等。对调试中出现问题,如炉水循环泵启动中、磨煤机风量显示值不正确、锅炉结焦、磨煤机螺旋输送器轴承两边端盖烧红和中心风控制等问题进行了处理,尤其是注意了水冷壁壁温及分离器出口温度的调整。168 h试运行的结果显示:主要运行参数达到设计要求,机组可稳定、安全运行。
China Resources Power Changshu second power plant No. 1 650 MW Turbine Generator Set, including China’s first 1952.21 t / h supercritical composite boiler. The boiler has a different from the drum boiler commissioning process, such as powder regulator surge pipe, the system starts, the safety gate setting, the initial adjustment of the boiler combustion and low load stable combustion debugging. In the debugging problems, such as the start of the boiler water circulation pump, the mill shows the amount of air flow is incorrect, the boiler coke, coal mill screw conveyor bearings on both sides of the cover burning red and the center of the wind control and other issues were dealt with, in particular, attention Water wall temperature and separator outlet temperature adjustment. 168 h trial run results show that: the main operating parameters to meet the design requirements, the unit can be stable and safe operation.
