Nitrogen Generator for Blanketing (Covering) Gas: A term used to describe an inert gas such as nitrogen or argon introduced into a furnace to prevent oxidation of the component parts being heat-treated. The flowrate and pressure of the atmosphere and the equipment type (i.e. gas-tight construction) must be sufficient to limit the influx of air.
The protective gases used in furnace atmospheres are usually a mixture of hydrogen, nitrogen, carbon dioxide (CO2), carbon monoxide (CO), and trace amounts of water.
