A relatively new type of waste treatment called plasma arc recycling Plasma torches like this are the heart of a plasma recycling plant. Where landfilling squanders valuable material and—at best—produces small amounts of methane energy, plasma recycling produces much more energy with no

Electric Arc Furnace an overview ScienceDirect

Plasma gasification Wikipedia

Content and consistency of the waste directly impacts performance of a plasma facility. Pre-sorting and recycling useful material before gasification provides consistency. Too much inorganic material such as metal and construction waste increases slag production, which in turn decreases syngas production.

“Effect of Foamy slag in Electric arc furnace on

The study also showed that with foamy slag, the optimum amount of FeO in slag was found in between 18-22 wt. % with the basicity of 1.8-2.2, which is a good agreement in prospects of yield as well as quality of the steel. KEYWORDS: ELECTRIC ARC FURNACE, FOAMY SLAG, MASS BALANCE, ENERGY BALANCE, HEAT LOSS IN EAF, SLAG ENGINEERING, STEEL INDUSTRY.

Electric Arc Furnace Steelmaking using Scrap

Another technique to employ during continuous feeding is use of a foamy slag. The radiation of arc energy to the sidewalls is reduced since the tips of the electrodes are surrounded by scrap or a foamy slag. In the present case, the equipment and electric arc furnace were not large enough to permit testing of either technique.

Pyrometallurgical recycling of electric arc

In pyrometallurgical recycling of EAF dust, the fume (e.g., zinc oxide fume) generated is usually polluted by chlorine and fluorine (Tsugita, 2003), while the residue/slag produced often has a high iron content (Barna et al., 2000) and a small amount of non-ferrous metals such as zinc and lead which can be recycled either in an electric arc

Recycling Plastics as a Resource for Electric Arc

Recycling end of life products, such as waste tires and waste plastics in iron-and steelmaking permits their use as energy and material resources. The current paper discusses the combustion efficiencies of blends of metallurgical coke (MC) with plastics for electric arc furnace (EAF) steelmaking.
