METHOD AND DEVICE FOR HEAT TREATING AT LEAST ONE EFFLUENT COMPRISING FUEL POLLUTANTS

摘要

The invention relates to a method for heat treating at least one effluent comprising fuel pollutants, wherein: a first comburent fluid and a combustible fluid are fed into a first area (A), said first comburent fluid and/or said combustible fluid being fed along a helical path; the comburent-combustible mixture is ignited such that a combustion phase is carried out along a helical path in the first area; said combustion phase is forced to pass into a second area (B) via a passage (P) restricted so as to give it the shape of an axially symmetrical vortex well flow; the effluent to be treated is fed at the area of axial symmetry of said vortex well flow; a second comburent fluid is fed into the second area (B) with a component tangential to the vortex well flow, characterized in that the second comburent fluid is injected in a stepped manner with a different angle of attack at each step. Said specific injection enables precise and gradual dispersion of the second comburent fluid into the entire body of the flame.
