核电高效紧凑新型蒸汽发生器设计研究

为了适应三代核电机组进一步提质增效的发展需求，在确保安全性的基础上，采用更加先进的技术、同时兼顾设计及制造技术的成熟性，研究设计了一款经济性更好、技术性能更先进的高效紧凑新型蒸汽发生器（ZH-J60型SG）。ZH-J60型SG设置了轴流式预热器和泥渣收集器，并改进设计了小型双级叶片汽水分离器。计算和分析表明，ZH-J60型SG提高了SG自然循环倍率，提升了整机功率重量比、出口蒸汽品质和运行可靠性，完全满足并在部分关键参数上超过第三代压水堆核电厂SG的水平。 

Design Research on Efficient and Compact Steam Generator for Nuclear Power Plants

For improving the quality and increasing efficiency of the third generation nuclear power plants, a more economical and compact new-type steam generator(ZH-J60 SG) is designed. ZH-J60 SG uses advanced technologies at the most, while ensuring the equipment safety and also paying much attention to the technical maturity in its design and manufacturing. This SG adds axial economizer and sludge collector, and adopts small vapor-liquid separator with double stages of vanes. The calculation and analysis show that recirculation ratio of secondary side flow, rating power to equipment weight ratio, outlet steam quality and operating reliability of ZH-J60 SG are much promoted. The technical performance of ZH-J60 SG reaches the top level of steam generators used for the third generation nuclear power plants, and some of the key parameters are even better.
