New Energy KNO₃

New Energy KNO₃

With the economic development and social progress, people put forward higher and higher requirements for energy. Finding new energy storage has become an urgent task facing mankind. The most effective and safest way to use clean energy is to convert it into electric energy, and realize optimal configuration, efficient transmission and convenient use through large power grid. As a clean and renewable energy, solar energy has attracted more and more attention, and its application fields are more and more extensive. According to the characteristics of solar energy and the needs of practical application, using solar power generation, especially photothermal power generation, is an effective way and method to solve the current energy, resources and environmental problems.

As a new type of energy storage, new energy KNO₃ is mixed with nitrate (40% potassium nitrate and 60% sodium nitrate), heated and melted into liquid to realize its heat storage function. In terms of function, its basic principle is the same as that of winter heating water as heat storage medium.

Advantages of the new energy KNO₃:

Low corrosion	Long life	Intelligence	Modularization

New energy KNO₃: The content of sulfur and chloride ion in molten salt is as low as 200ppm (generally 100ppm is the best in the market).

New energy KNO₃: The service life of the heat storage system is more than 30 years, and there is no limit on the number of cycles during operation.

New energy KNO₃: In addition to on-site monitoring, DCS system can be used for remote monitoring.

New energy KNO₃: The unit of solar thermal power generation is 50MW, and the unit of clean energy heating is 100000, 500000 and 1 million square meters or n * 50MW.

Application

Solar thermal power generation: the solar thermal power station uses molten salt for solar thermal power generation. This technology uses a powerful mirror to focus solar heat to generate steam, so as to drive the power turbine. The excess heat generated during the day can be used to heat a large amount of salt, which can absorb a considerable amount of heat. When the sun sets or the day is cloudy, the heat stored in molten salt is used to generate steam to drive power turbines.

Coal to electricity: the coal-fired boiler equipment of the central heating system is transformed into a molten salt heat storage electric heating system by using valley power, wind and light. The molten salt is electrically heated by using valley power and other energy at night, and the circulating water is heated to the heating temperature by salt water heat exchanger during the day. It can be distributed in villages, towns, communities, industrial parks, commercial buildings, etc Centralized application in cities according to the radiation range can achieve zero pollution and zero emission, which helps to alleviate the haze problem caused by coal heating in winter.

Industrial waste heat utilization: there are a lot of intermittent waste heat in industrial processes. These fields mainly include: high temperature flue gas waste heat, slag waste heat, product waste heat, cooling medium waste heat, combustible waste gas waste heat, chemical reaction waste heat, condensate, waste water waste heat, etc. These waste heat can be stored through the molten salt heat storage system and converted into a stable heat source that can provide continuous heating or hot water, so as to save energy and reduce consumption.
