The purpose of this work is to compare industrial trials of modernized intermediate SPP-500-1 moisture separators-heaters of the K-500-65/3000 turbines in the No. 4 unit of the Leningrad NPP and the No. 1 unit of the Smolensk NPP. It was found that the distribution of the separated moisture along the perimeter and height of the steam space at the egress from the separation units is uniform in both NPP. A very small increase of the moisture concentration at the wall was obtained in individual apparatus at the Smolensk (No. 24) and Leningrad (No. 72) NPP. The flow rate of the separated material and the condensate of the warming steam, as measured on the Nos. 1 and 2 turbines of the Smolensk NPP, is close to that obtained on the Nos. 7 and 8 turbines of the Leningrad NPP. In the course of the industrial trials, it was shown experimentally that the moisture and flow rate are the same. This confirms the reliability of the results, which after modernization are close to the design-basis level.

列宁格勒和斯摩棱斯克核电厂水汽分离器-再热器现代化分离部分的工业试验

这项工作的目的是比较列宁格勒核电厂 4 号机组和列宁格勒核电厂 1 号机组 K-500-65/3000 汽轮机的现代化中间 SPP-500-1 水分分离器-加热器的工业试验。斯摩棱斯克核电站。发现分离的水分沿分离单元出口处蒸汽空间的周长和高度分布在两个核电厂中是均匀的。在斯摩棱斯克（第 24 号）和列宁格勒（第 72 号）核电厂的单个设备中，壁上水分浓度的增加非常小。在斯摩棱斯克核电站 1 号和 2 号汽轮机上测得的分离材料和暖蒸汽冷凝物的流量与在列宁格勒核电站 7 号和 8 号汽轮机上测得的流量接近。在工业试验过程中，实验表明，水分和流速是相同的。这证实了结果的可靠性，经过现代化改造后接近设计基准水平。
