On the other hand, heat transfer (chemical energy) from the post-combustion reaction to the metal melt is also poor, since the post-combustion reaction takes place above the slag line, which in turn acts as an insulator, with the result that heat transfer (chemical reaction) to the metal melt becomes less valuable.ĩ. In addition, part of the generated heat (chemical energy) is lost to heating the N present in the air entering through the tap hole and the oven door 2. However, the heat transfer (chemical energy) from the reaction of the CO generated in the furnace with the oxygen blown into the furnace or present in the air to the solid charge is very small, since this post-combustion reaction takes place in the upper part of the furnace, in the region comprised between the slag line and the exhaust pipe, and the energy contained in this gas is rapidly dissipated in the upper part of the furnace and consequently is discharged via the exhaust system, rather than being transferred to the solid charge to the desired extent.
