Abstract
(DE)
Die Erfindung betrifft einen Plasmabrenner, der in ein Gefäß hineinragend an einer Tragvorrichtung befestigt ist und eine an einer Brennerlanze angeordnete Düse sowie ein innerhalb der Brennerlanze angeordnetes Hauptelektrodenrohr mit einer Hauptelektrode aufweist, zu der gasförmige und flüssige Medien sowie der elektrische Strom über koaxial angeordnete Rohre zugeführt werden, wobei eine ringförmige Isolierung (21) um die Hauptelektrode (10) im Bereich ihres Fußendes vorgesehen ist, die die Elektrode (10) ringförmig umfaßt, und an dieser Isolierung der Mantel (33) der von der Tragvorrichtung gehaltenen doppelwandigen Brennerlanze (30) befestigt ist.
(EN)
The invention concerns a plasma torch which is mounted on a support structure so that it extends into a container. The burner has a lance fitted with a jet nozzle and an electrode tube, fitted with a main electrode, located inside the lance. Gaseous and liquid media, as well as the electric current, are fed to the electrode through coaxially pipes. The bottom of the main electrode (10) is surrounded by an annular insulating element (21) which forms a ring round the electrode (10). The outer wall (33) of the double-walled lance (30) carried by the support structure being fixed to this insulation.

La présente invention se rapporte à un chalumeau à plasma lequel est fixé à un dispositif porteur, de manière à faire saillie dans un récipient, et lequel présente une buse montée sur une lance de chalumeau, ainsi qu'un tube à électrode principale monté dans la lance de chalumeau et comportant une électrode principale à laquelle sont amenés, par des tubes disposés coaxialement, des fluides gazéiformes et liquides, ainsi que le courant électrique, une isolation annulaire (21) entoure l'électrode principale (10) près de son pied, en formant un anneau. Sur cette isolation est fixée l'enveloppe (33) de la lance de chalumeau à double paroi (30) retenue par le dispositif porteur.
