Abstract (en)
[origin: JPH04222639A] PURPOSE: To provide a method and a device for a dynamic separation of two zones, to reduce gas consumption in the two zones and also to ensure an effective dynamic separation of the two zones. CONSTITUTION: In order to ensure a bi-directional dynamic separation between the two zones 10, 12, a gas curtain constituted by three juxtaposed gas streams or jets 28, 30 and 32 is formed between the zones. The central stream or jet is relatively fast and serves to stabilize two relatively slow lateral streams or jets 30, 32. The latter ensure the relative confinement of the two zones by means of their tongues 30a, 30b and their flow rate is determined in such a way as to supply the relatively fast stream with the gas necessary for its full development. In the case where one of the zones 10 has a reduced volume, an additional gas flow of flow rate can be injected into the zone.
