Its main steam pipe (main pipeΦ 450× 41, branch pipeΦ 335× 31)uses 1- 2 mode in the second stage 2× 300 MW unit extension project in ShanXi HuaNeng YuShe power plant.
山西华能榆社电厂二期2×300MW机组扩建工程,其主蒸汽管道(主管Ф450×41,支管Ф335×31)采用1-2制方式。
On-line valve test results showed that the fault was caused by the little flow through the left-side main steam valve with a block or very small opening.
为查找原因,从数字式电液(DEH)调节系统的控制逻辑、汽轮机调门的流量特性和阀门活动过程等方面进行了分析,并通过阀门在线活动试验,最终确定了机组故障原因是左侧主蒸汽门堵塞或开度很少致使其通流量很小。
For the coordinated controlled large size thermal power units,the most main cause of main steam pressure fluctuation is the overshooting of fuel.
主蒸汽压力是蒸汽品质的重要体现,协调控制的大容量火电机组,引起主蒸汽压力波动的最主要内因就是燃料的过调,文中从调节参数、磨煤机的启停、煤质的变化和负荷的变化等4个方面对燃料过调的影响进行了分析并提出了一定的解决办法,同时也分析了减温水量对主汽压力的影响。
