The molten salt is a mixture of potassium nitrate (KNO3), sodium nitrite (NaNO2) and sodium nitrate (NaNO3). The powdered molten salt is heated above 142℃ in the heat carrier furnace, make sure the molten salt recycling in the melt flow state, and the maximum operating temperature up to 480℃.
The molten salt furnace adopts coal as fuel, and takes the molten salt as heat medium. A circulating pump is used to create liquid-phase circulation of liquid molten salt, then the thermal energy will be transmitted to the heat using equipment. After unloaded in the heat using equipment, the heat molten salt will return to the furnace to be reheated.
Main Characters of Molten Salt Furnace
- High automaticity, prompt start and stop, high reliability.
- The thermal efficiency is higher, and the temperature of liquid molten salt will up to 480 ℃.
- Heating temperature is more stable by adjusting precisely, and it is easier to obtain higher working temperature under lower pressure.
- There are complete operating control and safety detection device on the system.
- High thermal efficiency, completely burning, stable output, better adaptability to variable load.
- Savings: It has the characteristics of high temperature and low pressure, it could reduce the pressure rating of the equipment, and could reduce the investment costs of the equipment.
