研究了高温熔盐蒸汽发生系统的蒸汽发生性能,特别分析了传热管在全部和部分浸没情况下系统的传热特性,结果表明:在实验的条件下,改变熔盐进口温度和流量对蒸汽量的影响很小;传热管部分浸没情况时的蒸汽量仅为传热管全部浸没时的1/2.在部分浸没情况下,随着熔盐流量增加熔盐出口温度先上升然后逐渐趋于稳定,稳定的流量值随熔盐的进口温度升高而增大;在全部浸没情况下,熔盐出口温度随着熔盐流量的增加近乎线性增大,没有观察到熔盐出口温度恒定现象.“,”Convective heat transfer performances of steam generator with molten salt materials have been experimentally investigated.Molten salt outside tube flowed downward and water inside tube flowed upward.The results showed that inlet temperature and flow rate of molten salt had little effect on the flow rate of steam.When the flow rate of feed water decreased, water level inside tube became low and steam flow rate dramatically reduced.Also, outlet temperature of molten salt would reach a constant value when the molten salt flow rate gradually increased, and the constant value increased as the increase of inlet temperature of molten salt.However, outlet temperature of molten salt linearly increased when the water level was as high as tube height.
