Atlantic salmon parr (Bolaks strain) were hatched at Nofima and initially kept in a FW flow‐through system in four separate tanks (,tank, size 3.2 m 3, diameter 2 m). When the fish reached a size of 20 g they were exposed to a 6‐week period of short day length (12 hour light, 12 hour darkness, 12L:12D) followed by a 6 week period of 24‐hour light to induce smoltification (Handeland ...

It is complicated to compare loads related to the ,RH, vacuum ,degasser,. The current load at 430 kW of HP steam should be treated as internal heat exchange, as the demand is covered by the steam from the BOF-converters. Using the available pinch curves, a study of possible improvements in three steps was carried out. The outcome is summarized in ...

For LF model, ‘,tank,–in–series’ model is used to simply consider the mixing phenomenon. The steel/slag reaction, lining dissolution, alloy addition and air absorption are also accounted for. On ,RH, modeling, three reaction sites in ,RH, vessel are defined: bath surface, inside bath and argon (Ar) bubble surface according to the decarburization and degassing mechanism.
