<p>The invention concerns a gas burner-type combustion device called burner (B) spraying a mixture of air and ignited gas in a pipe outlet, characterized in that it is equipped with a mobile diffusing cone (200) whereof the top (210) is arranged at least upstream of the flame-generating zone to ensure explosion of the air mixture with the gas, the relative displacement of the cone (200) along an axis of diffusion defined by the flames enabling the power of the latter to be adjusted. The invention also concerns a method for operating said device for use in thermal weed control.</p> |
