METHOD AND ARRANGEMENT FOR PREVENTING GAS FROM LEAVING AN OPENING OF A VESSEL

摘要

An arrangement (10) for preventing egress of a gas from a first opening of a vessel, the vessel including at least one other opening through which the gas can leave the vessel, the arrangement comprising an open passage (48) extending substantially around the first opening, the open passage (48) receiving a flow of gas such that the flow of gas leaves the open passage and flows towards and into the vessel to cause a gas from the environment external to the vessel to be drawn into the vessel. The arrangement may comprise a Coanda surface. The arrangement may be in the form of an inert for placement in the opening to the furnace.
