Regenerative hot blast stove and cross over conduit for such a regenerative hot blast stove

摘要

Regenerative hot blast stove comprising a combustion shaft (1), a regenerative shaft (2) arranged adjacent to the combustion shaft, and a cross over conduit (13) connecting the combustion shaft (1) with the regenerative shaft (2) for enabling gas flow from the combustion shaft via the cross over conduit into the regenerative shaft, which cross over conduit comprises a transverse section for at least bridging a gap between the combustion shaft and the regenerative shaft, the transverse section being essentially formed of a refractory wall (28) extending around a bore (16), the bore (16) leading to a first and a second connecting opening for connecting the cross over conduit with the combustion shaft and the regenerative shaft, wherein at least the first connecting opening is provided in the refractory wall of the transverse section, the connecting opening extending through the refractory wall to the bore.
