To enable a significant flow of liquid, gas or mixed hydrocarbons to be eliminated cleanly and safely, particularly during a well test phase, a burner comprises two concentric apertures, rotationally symmetrical about a common axis, enabling a hollow flame to be generated. The central aperture (20), intended for liquid or mixed products supplied by a conduit (12), consists of 2 concentric male (22) and female (21) conical parts, with the spacing (25) therebetween being continuously adjusted by the axial movement of the rod (23) which carries the male component (22) and which is centred by a centring component (24) in the conduit pipe (12), which carries the female component (21). The peripheral aperture (60), intended for gas products or an auxiliary airflow, also consists of two concentric male (62) and female (61) conical parts, between which the spacing (65) is not necessarily continuously variable during burning. |
