Abstract:
1. A system for a tower-type thermoelectric solar plant that uses a molten salt heat transfer fluid, the system comprising: a cold salt storage tank for storing a quantity of the molten salt heat transfer fluid in a cold state; a hot salt storage tank for storing a quantity of the molten salt heat transfer fluid in a hot state; a mixture tank; a receiver through which the molten salt heat transfer fluid flows and that receives concentrated solar radiation for heating the molten salt heat transfer fluid, the receiver having an inlet and having an outlet from which molten salt heat transfer fluid in the hot state exits the receiver, wherein the outlet of the receiver is connected to both the hot salt storage tank and the mixture tank; and a supply line connecting the cold salt storage tank with the mixture tank; wherein: heat transfer fluid in the cold state is supplied through the supply line from the cold salt storage tank to the mixture tank; a first portion of the molten salt heat transfer fluid in the hot state exiting the receiver is directed to the hot salt storage tank to be stored; a second portion of the molten salt heat transfer fluid in the hot state exiting the receiver is supplied to the mixture tank; the heat transfer fluid in the cold and hot states supplied to the mixture tank are mixed in the mixture tank to form a mixture of cold and hot molten salt heat transfer fluid at an intermediate temperature; and the mixture of cold and hot molten salts is supplied from the mixture tank to the receiver via the inlet of the receiver to be heated in the receiver.
