摘要：

Molten　salts　as　thermal　energy　storage　(TES)　material　have　been　numerously　studied.　The　annular　baffle　immersed　in　single　tank　can　improve　the　heat　discharging　performance　(HDP)　of　the　TES　system.　The　different　annular　baffle　conditions　are　experimentally　studied　in　single　tank　TES　system,　the　working　conditions　are　set　as　atmospheric　pressure,　vacuum　and　filled　with　solar　salt　in　the　annular　baffle.　The　results　present　that　the　effective　heat　discharging　time　(HDT)　of　working　condition　C　(filling　the　solar　salt　in　the　annular　baffle)　and　working　condition　B　(the　vacuum　treatment　of　the　annular　baffle)　is　increased　by　21.1%　and　6.1%,　respectively　compared　with　the　working　condition　A　(the　atmospheric　pressure　in　the　annular　baffle).　The　highest　heat　discharging　efficiency　(HDE)　is　93.93%　obtained　by　working　condition　C,　while　the　HDE　of　working　condition　B　and　A　is　91.16%　and　83.2%,　respectively.　This　research　provides　a　significance　guide　for　the　design　and　application　of　single　tank　TES　system.
