“…Alternative designs exist for heating scrap with waste gases and direct combustion for energy savings compared to the EAF route. [58,59] It is assumed that heating to the process temperature in the proposed furnace is as efficient as the conventional route, and that a continuous process to the EAF could be developed, but 10 to 20 kWh/tonne [60] is added to each high-temperature solid scrap process to account for heat losses during the transition to the EAF. The process heat energy would be for powering the furnace during the treatment-maintaining 1000°C for an additional 10 minutes, and heating the additional reactants.…”

“…Zhou et al [5] relatam que um queimador a oxicombustível típico, em regime de operação durante a fusão, produz fluxos de gases com velocidades entre 40 e 60 m/s. Outros autores [2,4,6] afirmam que a turbulência e o arraste mecânico produzido por estes campos de velocidades são os principais inconvenientes operacionais da utilização de fornos rotativos. Os rendimentos do carburante coque de petróleo calcinado, com granulometria de 1 a 3 mm, quando adicionado à carga sólida aquecida, durante a produção de ferros cinzentos e nodulares, em fornos rotativos a óleo de xisto e gás natural, são apresentados na Tabela 7.…”

“…Seventy-two abstracts were retrieved after removing repeated abstracts, review articles and abstracts not related to the topic. Upon application of inclusion criteria (e.g., efficiency, costeffectiveness, output purity), a total of 28 articles were fully examined and twenty-one studies were finally selected for use in our evidencebased methodology (Andrews et al, 2000;Baldock and Short, 2000;Cow-perthwaite et al, 1980;Diaz et al, 2001;Ferracin et al, 2002;Frias et al, 2002;Agrawal et al, 2004;Rabah, 1998;Ramus and Hawkins, 1993;Reddy, 2003;Raghavan et al, 2000;Tianjun and Qichang, 1999;Errington et al, 2005;Arthur and Edwards, 2003;Zhang et al, 2008;Ziebik and Stanek, 2006;Barakat, 1998;Ettler et al, 2005;Ryzhenkov et al, 2006;Socolow and Thomas, 1997;Yender, 1998).…”
