The basic properties of potassium nitrate and sodium nitrate
1.Potassium nitrate
The chemical formula is KNO₃, which is a colorless transparent rhombic crystal or rhombic crystal or white powder, odorless, non-toxic, salty and cool. It is a chlorine-free potassium compound fertilizer with high solubility, and its effective components nitrogen and potassium can be quickly absorbed by crops without chemical residues.
2.Sodium nitrate
The chemical formula is NaNO₃, which is a hygroscopic colorless transparent triangular-system crystal. It decomposes when heated to 380℃. When dissolved in water, it absorbs heat, the solution becomes cold, and the aqueous solution is neutral.
Principle and application of molten salt energy storage
1.Principle of molten salt energy storage
Molten salt energy storage technology takes advantage of the temperature difference of molten salt in the process of heating and cooling to achieve heat energy storage. Binary salt Solar Salt (60% sodium nitrate +40% potassium nitrate) is the heat transfer and storage working medium selected by most photothermal power stations at present, its melting point is 220℃, and the maximum working temperature can reach 600℃.
2.Heating supplying
The low-temperature molten salt is heated and stored in the high-temperature molten salt tank using valley electricity, and the high-temperature molten salt is used for heating duringduring the daytime while the energy consumption is at peak .
3.Surplus heat recovery
The surplus heat is recovered and used for heating and power generation through the molten salt heat storage system.
4.Photothermal power generation:
The tower photothermal power station tracks the sun in real time through a large-scale heliostat, focuses the sunlight on the heat absorber at the top of the tower, stores heat energy through high-temperature molten salt, and realizes the conversion of "light energy - heat energy - mechanical energy - electric energy".
5.Energy storage peak balancing:
Energy storage peaking is an important energy management technology, which uses energy storage equipment to optimize and balance the power grid to meet the fluctuation of power demand.
Marketing demands and future outlook
Molten salt heat storage technology, with its unique advantages of high temperature molten salt as a heat storage medium, is showing fast market growth potential worldwide. With the continuous landing of solar thermal power generation projects, the supply of sodium nitrate, potassium nitrate, nitric acid and other products in the upstream may appear a certain gap. As the main raw materials of molten salt, the reduction of supply indicates that the future demand growth of molten salt heat storage market may bring about a short supply situation.
In summary, potassium nitrate and sodium nitrate have important application value in the field of molten salt energy storage, and their market demand is expected to continue to grow with the development of new energy industry.If you have any demand for potassium nitrate and sodium nitrate, please contact us and you will be satisfied with our product and service support!
