The apparatus consists basically of an atmospheric burner, a combustion chamber, and means for creating a vacuum within the combustion chamber. To provide optimum combustion using different gases from one gas family, means for detecting at least one apparatus temperature and means for controlling the primary air flow according to the temperature detected are provided. Various applications are described wherein the temperature is measured at the surface of a burner diffuser and the primary air is controlled to keep the temperature below a critical value and the flame stable. For improved operation at the ignition stage, the flow rate of the primary air is set at a comparatively low predetermined starting value.

A method for controlling air being supplied to a gas combustion apparatus having an atmospheric burner comprising: a) introducing fuel gas in a class of fuel gases and a stream of primary air into a suction duct of a burner to form a fuel-gas air mixture; b) introducing said mixture into a diffuser

A method for controlling air being supplied to a gas combustion apparatus having an atmospheric burner comprising: a) introducing fuel gas in a class of fuel gases and a stream of primary air into a suction duct of a burner to form a fuel-gas air mixture; b) introducing said mixture into a diffuser associated with said burner and forming a flame region above a surface of said burner in a combustion chamber of said combustion apparatus, said primary air being introduced into the suction duct in an amount responsive to at least one temperature detected at or within the flame region of said burner, and in steady-state operation, said amount of primary air varying between a value substantially equal to the amount required for stoichiometric combustion of the fuel gas and a value largely exceeding said amount required for stoichiometric combustion of the fuel as; setting the burner to provide optimum combustion of said fuel gas, said optimum combustion corresponding to a desired temperature at or within said flame region of said burner; and varying said amount of primary air admixed with said fuel gas to change the ratio of primary air fuel gas to cause said detected temperature to approach said desired temperature.
