The combined installation comprises at least one metal production unit (II), including at least one, and typically a series of metal production or treatment units ( ), and at least one air gas separation unit (III) including at least one outlet for at least one air gas ( ), the units being supplied with compressed air with a low water vapor content by a common compressed air production unit (I), and with at least one of the gas outlets ( ) from the separation unit (III) connected to at least one of the devices ( ) of the production unit, to supply the latter with gas.

In a combustion process permitting reducing the production NO.sub.x, there is ejected via a burner (1) at least one flow of combustible gas, at least one flow of an oxygenated gas supporting combustion and at least one flow (10) of one of these gases in liquid phase. In an oxyburner, one portion (between 13 and 35%) of the oxygen is injected in liquid phase. In an aeroburner for natural gas, one portion (10 to 30%) of this latter is ejected in a coherent liquid jet. Use particularly in glass furnaces and heaters.

The combined installation comprises at least one metal production unit (II), including at least one, and typically a series of metal production or treatment units (1-6), and at least one air gas separation unit (III) including at least one outlet for at least one air gas (14-18), the units being supplied with compressed air with a low water vapor content by a common compressed air production unit (I), and with at least one of the gas outlets (14-18) from the separation unit (III) connected to at least one of the devices (1-6) of the production unit, to supply the latter with gas.
