Abstract：

To　observe　the　influence　of　thermal　stratification　on　the　discharging　process　of　molten　salt　in　small　single　thermal　storage　tank,　the　discharging　process　of　molten　salt　with　or　without　thermal　stratification　were　investigated.　The　parameters　including　molten　salt　temperature,　water　temperature　at　the　outlet　of　the　heat　exchanger　and　the　cumulative　heat　discharging　efficiency　were　analyzed　in　details.　It　was　found　that　maintaining　the　thermal　stratification　of　the　molten　salt　during　the　heat　discharging　process　is　the　key　factor　to　improve　the　cumulative　heat　release　efficiency　of　the　single　tank.　The　disturbance　caused　by　the　heat　discharging　of　the　immersed　heat　exchanger　can　destroy　the　molten　salt　thermal　stratification,　so　it　is　necessary　to　optimize　it.　The　results　provide　an　effective　basis　for　the　optimization　of　small　single　thermal　storage　tank　system　with　immersed　heat　exchanger.　©　2018,　Science　Press.　All　right　reserved.
