The molten salt heating furnace can obtain a higher working temperature under a lower operating pressure, the heating temperature is stable, can be adjusted accurately, and the thermal efficiency is high.

Molten salt is a mixture of potassium nitrate (KNO3), sodium nitrite (NaNO2) and sodium nitrate (NaNO3). The heat carrier furnace heats the powdered molten salt to a melting point of 142°C or higher, so that it can be recycled in a molten state. The highest working temperature can reach 600℃.
