１０ＭＷ高温气冷实验堆（ＨＴＲ－１０）的蒸汽发生器为直流型、小盘管组件式结构，盘管弯曲半径小，工作压力为中压范围，由此而带来两相流体流动的不稳定性问题是ＨＴＲ－１０蒸汽发生器研究的主要问题。介绍了用Ｋｈａｂｅｎｓｋｙ等方法分析ＨＴＲ－１０蒸汽发生器的密度波不稳定性。分析了入口欠热度、入口节流度、加热功率、质量流量、系统压力、热负荷及出口蒸汽干度等对ＨＴＲ－１０蒸汽发生器密度波脉动的影响。分析表明在ＨＴＲ－１０蒸汽发生器设计工况下不会发生密度波脉动。
The steam generator for the 10MW HTR-10 is a direct current, small-coil assembly with a small coil bend radius and a working pressure in the medium pressure range, resulting in a two-phase fluid flow The stability issue is a major issue in the HTR-10 steam generator research. The Krabensky method is introduced to analyze the density wave instability of HTR-10 steam generator. The effects of inlet underheating, inlet throttle, heating power, mass flow rate, system pressure, heat load and outlet steam dryness on the pulse wave density of HTR-10 steam generator were analyzed. Analysis shows that density wave pulsation does not occur at HTR-10 steam generator design conditions.
