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.
