Solar thermal power generation refers to the technology of converting solar thermal energy into thermal energy of heat-carrying fluid and then transferring the thermal energy to the power generation system for power generation It is more environmentally friendly than photovoltaic power generation more stable than wind power generation and can be directly connected to the grid for power supply It is currently the most promising green energy source
In solar thermal power generation molten salt for heat storage is an extremely critical system Molten salt is mainly potassium nitrate or mixed salt mainly made of potassium nitrate Due to the corrosiveness and point requirements for equipment the quality requirements for potassium nitrate used in molten salt are very strict In addition to high purity requirements the content of impurity ions Extremely low especially the content of chloride ion CI which is the culprit causing corrosion and affecting the service life of equipment
The high-purity potassium nitrate produced by our company has a main content of more than 99.9 a chloride ion CI content of less than 40ppm a carbonate of less than 40ppm and a sulfate of less than 30ppm It is the best choice for solar molten salt
