Abstract
DC arc plasma torch, in particular intended for obtaining a chemical substance from a plasma-generating gas (P) which includes said substance. According to the invention: the electrode (2A) is in communication with the chamber (3) for injecting the plasma-generating gas via a tubular piece (2B) through which the arc (10) passes and which constitutes the reaction chamber in which said plasma-generating gas (P) gives rise to the plasma (13) under the action of the electric arc (10); and means (7, 8) are provided which make it possible to form a fluid barrier (14) between the electrode (2A) and the plasma (13).
