摘要： Formation of nitrogen oxides and/or soot is obviated by mixing recycled combustion gas with incoming comburant supplied to a burner via a distribution opening and controlling the mass flow rate of combustion gas being recycled with respect to the mass flow rate necessary for the gaseous comburant, the mixture being passed to the burner as a turbulent flow in which the ratio between the kinetic momentum flux of the mixture and the product of the radius of the said distribution opening times the axial movement quantity flux of the mixture has a value at least sufficient so that the said turbulent flow produces a recirculation of the said mixture within the combustion chamber in the form of a toroidal vortex. This is achieved by apparatus comprising a mixing enclosure having two inlets each provided with means for regulating the size of its aperture, and an outlet, inlets communicating respectively with the atmosphere and with a duct for combustion gases, the outlet being connected to the inlet of a ventilator whose outlet communicates with gas mixture supply means arranged coaxially to a fuel injection nozzle in order to impart a turbulent motion to the gas mixture emitted from the supply means.
