Combined with integrated oxygen lances and permanent CO measurement, this furnace type ensures extra-low specific gas consumption.
If you add an integrated post-combustion system, your URTF from Hertwich (HE-URTF) will comply with even the strictest European emission standards. Today, most URTF operate with the standard low-salt process. They achieve an optimum metal yield with a salt factor of 0.2 - 0.5. Yet there is a greener alternative - because the salt-free AluRec® process saves money and completely avoids hazardous salt slag.
