CEEF has officially been awarded a national invention patent (Patent No. ZL 2012 1 0433866.2) for a proprietary “Molten Salt Solar Energy Storage System.” This technological breakthrough leverages our decades of expertise in manufacturing high-efficiency thermal fluid heaters to enable 24-hour continuous operation for commercial solar power stations.
How the Dual-Medium Thermal Storage Cycle Works
To achieve uninterrupted thermal energy transfer day and night, the system utilizes a highly engineered dual-medium mechanism. During daylight hours, the solar collection array heats Therminol VP-1, a specialized synthetic heat transfer fluid. This fluid is circulated through advanced thermal oil heaters (often casually referred to in the market as thermal oil boilers) to rapidly elevate the temperature of the molten salt. This superheated molten salt is then deposited into large-scale, heavily insulated tanks for high-capacity thermal energy storage.
At night, the thermal exchange cycle reverses. The stored molten salt is utilized to reheat the Therminol VP-1, which subsequently boils water to generate high-pressure steam. This continuous steam flow drives the station’s turbines, producing steady, reliable electricity even without direct solar irradiation.
Pioneering Renewable Energy Hot Oil Applications
The efficiency of this continuous solar storage cycle relies entirely on the precise, leak-free management of liquid heat carriers under extreme temperatures. As a premier manufacturer of industrial heating equipment, CEEF’s mastery over high-temperature hot oil systems directly enabled this innovation.
By adapting our proven hot oil heater architecture to the rigorous, round-the-clock demands of the renewable energy sector, we ensure exceptional heat exchange stability for large-scale solar arrays. This patented system represents a major milestone in transitioning our heavy-duty thermal engineering capabilities into the green energy generation market.
