Microwave selective heating of electric arc furnace dust constituents toward sustainable recycling: Contribution of electric and magnetic fields [PDF]

, 2021
Microwave heating of waste electric arc furnace dust (EAFD) for the purpose of its remediation has been studied extensively. However, these studies considered EAFD as a bulk material without addressing either the relative response of its individual ...

Assessment of Solid Wastes and By‐Products as Solid Particle Materials for Concentrated Solar Power Plants

Solar RRL, Volume 6, Issue 6, June 2022., 2022
The revalorization of wastes and by‐products to be used as solid particles inconcentrated solar plants leads to cost savings and progresses toward a sustainable technology. A complete characterization of wastes and by‐products before and after thermal treatment is reported, showing that by‐products from the steel industry have the most suitable ...

Recovery of Cs-137 from electric arc furnace dust by lixiviation [PDF]

, 2022
An orphan radioactive source of Cs-137 was inadvertently melted in an electric arc furnace, generating large volumes of electric arc furnace dusts contaminated with Cs-137 (137Cs-EAFD). This work proposes the Cs-137 recovery from 137Cs-EAFD by applying a

Off‐Gas Waste Heat Recovery for Electric Arc Furnace Steelmaking Using Calcium Hydroxide (Ca(OH)2) Dehydration

steel research international, Volume 91, Issue 11, November 2020., 2020
A novel process for extraction, storage, and utilization of off‐gas waste heat is discussed. Key difference to other concepts is the application of entrained flow Ca(OH)2 dehydration. Waste heat exchangers are avoided. Balancing of power‐off times for the reference plant requires just small heat storage tanks of 6.5 m3. In total, a net power generation
