摘要
本文介绍了给煤机断煤后,磨煤机因密封风差压低,先后跳闸,运行调整不及时,煤水比失调,给水量远大于给煤量,主蒸汽温度急剧下降,造成汽轮机高压缸应力过大,引起锅炉MFT,通过详尽的分析,得出了准确的结论,并提出整改措施。
This article describes the machine off after coal coal, wind mill due to poor seal down, has tripped, run adjustment is not timely, ratio imbalance, to the amount of water is much greater than the amount of coal, the main steam coal water temperature fell sharply, resulting in the high pressure turbine too much stress, causing boiler MFT, conclusions, and propose corrective measures. through detailed analysis, come to accurate
