The device comprises a sleeve (3) for recirculation of burnt gas, in a tubular form, which is coaxial to the burner and disposed in front of the nose (2) of the latter, this sleeve having a thin wall and a frontal orifice of dimension slightly greater to that of the nose of the burner. The distance between the front orifice and the nose of the burner, and also the length L and the diameter D in front of this burner is determined as a function of the form and the volume of the combustion chamber (1), of the power of the burner and the angle of atomization of the fuel. |
