CO2 heater

key word:Heat exchange element


Product description

In order to avoid the explosive gas produced by the mixture of air and hydrogen before the hydrogen cooled generator is ready for power generation or when the generator is turned from power generation to shutdown for maintenance, when the hydrogen content in the mixture of hydrogen and air is between 4% and 1% In order to ensure safety, carbon dioxide is used as the intermediate isolation gas, so the gas conversion of hydrogen cooled generator should be carried out. When the generator carries out gas replacement, the liquid carbon dioxide gas in the bottle suddenly changes to the gas state through the pressure reducing valve. This instantaneous phase state change is accompanied by a large number of endothermic processes, which makes the gas temperature drop sharply. When the gas with lower temperature enters into the generator unit, the local temperature inside the generator will decrease and the water vapor inside the generator will condense to form condensation. The larger temperature difference will affect the insulation of the generator, and the surface dew will also affect the dielectric properties of the insulation, so it is necessary to heat carbon dioxide.
