HEIGHT-ADJUSTABLE RING PROTECTION SKIRT BETWEEN AN INDUSTRIAL OVEN IN PARTICULAR A CONVERTER OVEN, AND A CHIMNEY HOOD

摘要

In a height-adjustable hood ring (1) between an industrial furnace, especially a converter (2) and a stack hood (3) arranged thereabove at a distance, the upper rim (8) of the hood ring (1) is at a distance from the stack hood (3), the upper rim (8) of the hood ring (1) forming an annular gap (9) with the stack hood (3). In the case of such a hood ring (1), a reliable annular-gap seal is achieved in a compact manner, if the hood ring (1) is equipped, at or near its top rim (8), with a device (10) for supplying a gaseous and/or vaporous barrier medium which seals the annular gap (9).
