Abstract

The furnace includes a vessel closed by a floating roof, and a sealing means mechanism between the roof and the vessel. The sealing mechanism includes two joint surfaces, one of which is arranged on the peripheral edge portion of the roof whereas the other is arranged on the peripheral edge portion of the vessel. The first surface is substantially toric and the second surface substantially frustoconical. The joint surfaces permit the centering of the roof relative to the axis of the vessel. The peripheral edge portion of the vessel is provided with a coping element on which one of the joint surfaces is arranged.
