昌江核电厂水汽集中取样装置优化分析

Concentrated Sampling Device Optimization Analysis of PWR Nuclear Power Plant Steam

本文运用对比分析的方法 ,对当涂火电厂水汽集中取样装置和昌江核电厂的二回路水汽集中取样装置进行分析评价。结果发现,当涂火电初期投资较少,系统结构简单,运行维护方便,但安全稳定性较差,能效低;昌江核电厂虽然初期投资相对较大,但其设备在安全和经济性能方面,有了较大的优化改进,是节能增效的有利措施。笔者针对昌江核电的水汽集中取样装置进行了深入分析,提出了自己的优化建议。

In this paper, the method of comparative analysis, of Dangtu thermal power plant water vapor concentration sampling device and the Changjiang nuclear power plant in the second loop of water vapor concentration sampling device were analyzed and evaluated. It was found that the Dangtu thermal power with less initial investment, the system has the advantages of simple structure, convenient operation and maintenance, but security and stability is poor, the low level of energy efficiency; Changjiang nuclear power plant although the initial investment is relatively large, but its equipment in safety and economic performance, improvement and optimization of large, is favorable measures for energy efficiency. The water vapor concentration of Changjiang nuclear power sampling device are analyzed, put forward the optimization suggestions.
