摘要

Inductive coupled plasma burner comprises a tubular burner channel (1), an induction coil (2) surrounding the burner channel and a dielectric envelope (3). The dielectric envelope comprises a closed or a porous structure (4). The porous structure or the clearance space is flowed through between the outer wall of the burner channel and the envelope by a fluid (5). The induction coil is closely located at the burner channel and the envelope reaches up to the induction coil in longitudinal axis direction of the overall arrangement, which is not yet enclosed. Inductive coupled plasma burner comprises a tubular burner channel (1), an induction coil (2) surrounding the burner channel and a dielectric envelope (3). The dielectric envelope comprises a closed or a porous structure (4). The porous structure or the clearance space is flowed through between the outer wall of the burner channel and the envelope by a fluid (5). The induction coil is closely located at the burner channel and the envelope reaches up to the induction coil in longitudinal axis direction of the overall arrangement, which is not yet enclosed. The burner-top of the clearance space or the porous structure is enclosed relative to the fluid flow. The fluid suctions radially arranged on burner-top is present in the envelope, where the fluid entry takes place via burner-under-side open clearance space.
