Procedure for inertised introduction of combustible and explosive substances into container

摘要

With the filling opening closed, the container inner space is pressurised with inert gas. The gas is controllably released as waste gas. With opening of the filling opening the release of waste gas stops and at the upper edge of the filling opening atmospheric air drawn in from an outer annular chamber. From an inner chamber formed as a push-in funnel a definitively composed amount of inert gas flows into the outer chamber and is drawn out of it.
