A new burner slashes NOx emissions from iron
01/05/2022Before being fed to the blast furnace, iron ore is first converted into pellets by, for example, a traveling-grate (TG) pelletizing plant. In this plant, so-called green pellets are conveyed through a furnace that heats the pellets to high temperatures to perform drying, partial calcination and induration. The pelletizing process generates considerable emissions of
