    摘要: A method and system for providing a controlled gaseous environment at the opening to a receiver and around a free liquid stream downwardly entering the receiver opening. The method comprises laminarly emitting at least two gas flows to extend and intersect over the receiver opening thereby forming an upward plume enveloping the free liquid stream.
