The purpose of filling the generator's cold water tank with nitrogen is to prevent corrosion and rust.
The fixed cooling water tank of the generator is usually filled with nitrogen during transportation or maintenance breakdown.
Nitrogen, with the chemical formula N2, is generally a colorless and odorless gas, and is generally non-toxic. Nitrogen is generally less dense than air. Nitrogen represents 78.12% (volume fraction) of the total atmosphere and is the main component of air. Under standard atmospheric pressure, when cooled to -195.8°C, it turns into a colorless liquid. When cooled to -209.8°C, liquid nitrogen turns into a snow-like solid. The chemical properties of nitrogen are inactive and it is difficult to react with other substances at room temperature. However, it can undergo chemical modifications with certain substances under temperature conditions.high nature and energy and can be used to produce new substances useful to humans. .
