摘要(Abstract)：
某发电厂2×600 MW超临界机组1号锅炉在整套启动调试期间遇到一次风机失速,引发锅炉MFT。分析了一次风机发生失速的主要原因,并针对调试、运行中发生的一次风机失速问题,提出了相应的避免或减轻一次风机失速的调整方法和预防措施,提高了机组的安全稳定性。
During complete startup commissioning of boiler No.1 in 2 ×600 MW supercritical unit in a power plant, a primary air fan stall occurred, resulting in boiler MFT(main fuel trip). This paper analyzes main reasons for the occurrence of the primary air fan stall and presents adjustment methods and preventive measures to reduce or mitigate primary air fan stall in accordance to the primary air fan stall in commissioning and operation to improve the security and stability of the unit.
