Abstract
During the heating of scrap in a container using sulfur-containing fuels for combustion, CaO, Ca(CO).sub.2, or CaCO.sub.3 powder is injected into the container to fix sulfur oxides generated during the combustion mainly as CaSO.sub.4. There is no need for special exhaust gas desulfurization, and, at the same time, slag formation is possible.
