| 摘 要： | 为研究熔盐蒸汽发生器的传热特性,以Solar Salt二元硝酸盐为工质,对熔盐与过冷沸腾水在蒸汽发生器中的传热规律进行实验研究.实验结果表明:熔盐传热系数随着水侧与熔盐的质量流速的增大而增大,随着水侧压力的升高而减小;当水侧在过冷水状态时,熔盐传热系数随着熔盐入口温度的升高而增大;当水侧在过冷沸腾状态时,熔盐传热系数随...

| Abstract: | In this study,a binary salt mixture(60%NaNO;and 40%KNO;,wt.)was used as the working substance to study the shellside heat transfer performance of molten salt-steam generator.The experimental results showed that the shell-side heat transfer coefficient in molten salt steam generator is affected by water pressure,water and molten salt flow flux,molten salt inlet temperature.In addition,multiple linear regression is used based on the experimental data to fit experimental correlation equation for the shell-side hea transfer coefficients,and with the maximum fitting errors of±10%. |
