Title:
MOLTEN SALT LAYERED ENERGY STORAGE SYSTEM CAPABLE OF SUPPLYING STEAM AT CONSTANT TEMPERATURE
Document Type and Number:
WIPO Patent Application WO/2022/088649
Kind Code:
A1
Abstract:
Disclosed is a molten salt layered energy storage system capable of supplying steam at a constant temperature. Several partition plates are arranged in a thermal storage tank from top to bottom, with each partition plate being provided with overflow holes. A heater comprises several heat exchange tubes that are in communication with each other in sequence, wherein the heat exchange tubes are located between adjacent partition plates at the bottom layer of the thermal storage tank; an outlet of a water inlet pipeline is divided into two paths, one of which is in communication with an inlet of the heater, and the other is in communication with a water inlet of a water-spray desuperheater via a desuperheating water pipeline; a first regulating valve is arranged on the desuperheating water pipeline; an outlet of the heater is in communication with a steam pipeline via the water-spray desuperheater; an outlet at the bottom of the thermal storage tank is in communication with an inlet of an electric heating furnace via a circulating pump; and an outlet of the electric heating furnace is in communication with an inlet at the top of the thermal storage tank. The system has the characteristics of high thermal storage capacity and a wide operating temperature range of molten salt, and also meets the requirement of the steam outlet temperature.
