In　this　study,　a　binary　salt　mixture　(60%　NaNO3　and　40%　KNO3,　wt.)　was　used　as　the　working　substance　to　study　the　shell-side　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　heat　transfer　coefficients,　and　with　the　maximum　fitting　errors　of　±10%.　©　2022,　Solar　Energy　Periodical　Office　Co.,　Ltd.　All　right　reserved.
