The invention concerns a Claus furnace gas burner consisting of at least five concentric tubes (T1-T5), forming five concentric gaps for introducing gas, the first tube (T1) being the tube with the smallest diameter and the fifth tube (T5) being the one with the largest diameter, wherein: the ends on the side of the Claus furnace of the third, fourth and fifth tubes are in the same plane, the two central tubes (T1, T2) are integral relative to each other and mobile along a central longitudinal axis of the burner relative to the other tubes (T3-T5), their ends on the Claus furnace side not exceeding the plane formed by the ends of the three other tubes, the gap formed between the first and second tubes (T1, T2) being terminated on the Claus furnace side by an injector oriented towards the periphery of the burner in the injecting direction of the gases into the burner. Depending on the ammonia content of the ammonia-containing gas to be treated in the Claus furnace, the two central tubes (T1, T2) are displaced to obtain total elimination of ammonia.
L'invention concerne un brûleur de gaz pour four Claus composé d'au moins cinq tubes concentriques (T1-T5), formant cinq espaces concentriques pour l'introduction de gaz, dans lequel: les extrémités du côtés du four Claus des troisième, quatrième tubes sont dans le même plan, les deux tubes centraux (T1, T2) sont solidaires l'un par rapport à l'autre et mobiles selon l'axe longitudinal central du brûleur par rapport aux autres tubes (T3-T5), leurs extrémités du côté du four Claus ne pouvant dépasser le plan formé par les extrémités des trois autres tubes, l'espace formé entre les premier et deuxième tubes (T1, T2) se termine du côté du four Claus par un injecteur orienté vers la périphérie du brûleur. En fonction de la teneur en ammoniac du gaz ammoniaqué à traiter dans le four Claus, les deux tubes centraux (T1, T2) sont déplacés de manière à obtenir une élimination totale de l'ammoniac.
