    摘要: The invention relates to a process and device for injecting at least one stream of a finely divided material into a hot gaseous flow, such as a plasma jet. According to the invention,--there is interposed on the path of said hot gaseous flow a screen pierced with a plurality of orifices spatially distributed about said hot gaseous flow so as to fractionate the latter into a plurality of elementary flows at least approximately in the same general direction; and--said stream of finely divided material, is led to at least one nozzle at least partially surrounded by said orifices, in order to create at least one stream of finely divided material whose direction is at least approximately similar to that of said elementary hot gaseous flows and surrounded by at least certain of them. The invention is particularly applicable to plasma chemistry.

    摘要: A plasma torch includes two tubular coaxial electrodes, at least one of which is axially movable between an operating position in which the movable electrode is spaced from the other electrode and an initiating position in which the movable electrode is in contact with the other electrode, thus establishing an electric short circuit so as to generate an electric arc upon rupture of the electric short circuit hen the mobile electrode is brought back to its operating position. Each electrode is contained in a support provided with a cooling circuit, through which a cooling fluid circulates. The cooling circuit associated with the movable electrode is provided with a seal which permits the electrode to be moved without creating any leaks in the cooling circuit.

    摘要: This invention relates to a plasma torch and a first and second electrode for use in a plasma torch. Each electrode includes a tubular intermediate part which is intended to come into contact with the arc feet and a pair of end parts which are intended to facilitate connection of the electrode to the other parts of the torch. Each electrode is disposed within an enclosed fluid circulation chamber within which a cooling fluid circulates. The intermediate and end parts of each electrode are at least ten millimeters thick. The individual parts of each electrode are connected together by a moisture-impervious, disassemblable, mechanical assembly which prevents the cooling fluid from coming in contact with the interior of the electrodes.
