低负荷下再热蒸汽温度偏低的原因及处理措施

Causes of Low Temperature of Reheat Steam under Low Load and Treatment Measures

针对某电厂600MW亚临界锅炉在低负荷时出现再热蒸汽温度偏低的实际情况,根据现场检查结果,初步分析原因;然后通过运行诊断及优化调整试验,对锅炉再热蒸汽温度偏低进行治理,取得了较好的治理效果。

In this paper,according to the field inspection results,the reason of the low reheat steam temperature in a 600MW subcritical boiler of a power plant is analyzed.Then,through the Operation Diagnosis and optimization adjustment test,the boiler reheat steam temperature is low,and a good effect is obtained.
