| Abstract: |
| The calculation formula of volume of molten salt, calculation formula of molten salt density under different temperatures, and iterative calculation formula of liquid level of salt tank in piping dissolving molten salt heating system were derived. The quantitative effect of temperature of returning salt on liquid level of salt tank was illustrated. A series of measures were put forward to prevent molten salt block accident. The improved startup and shutdown mode is relatively inexpensive and reliable. |
