Abstract
(EN)
The condensate extraction device, within the internal cavity (4) of the cylinder, consists of a partition (10) arranged in front of the bottom (12) of the internal cavity. An opening (9) between the internal cylinder wall (8) and the edge of the partition (10) allows the condensates to pass and atomize behind the partition (10) where they are discharged at the level of the axis of the cylinder. The open section (9) between the partition (10) and the cylinder is relative to the diameter of the cylinder. In large-diameter cylinders, the edge of the partion (10) may include serrations which at the same time act to centre said partition in the cylinder.
(FR)
Le dispositif d'extraction des condensats, à l'intérieur de la cavité interne (4) du cylindre, consiste en une cloison (10) disposée devant le fond (12) de la cavité interne. Un orifice (9) entre la paroi cylindrique interne (8) et la périphérie de la cloison (10) permet le passage des condensats et leur atomisation derrière la cloison (10) où ils sont évacués au niveau de l'axe du cylindre. La section de l'ouverture (9) entre la cloison (10) et le cylindre, est fonction du diamètre du cylindre. Pour des cylindres de grand diamètre, la bordure périphérique de la cloison (10) peut comporter des crénelures qui, en même temps, servent au centrage de ladite cloison dans le cylindre.
