摘要
Abstract
Taking the MW level dual-tank molten salt heat storage system as the research object,a mathe-matical model of the molten salt(solar salt)melting process in the molten salt heat storage tank is estab-lished.The heat transfer characteristics in the melting process and the influence of the surface temperature of the electric heating tube are simulated and analyzed.In the early stage of heating the molten salt,the heat trans-fer method is mainly thermal conduction.As the molten salt around the electric heating tube melts,the heat transfer in the liquid phase zone is mainly through natu-ral convection.Increasing the surface temperature of the electric heating tube is conducive to expanding the pro-portion of the liquid phase zone and promoting the natu-ral convection heat transfer.关键词
