Abstract
"MéTODO E APARELHO PARA USO APERFEIçOADO DE FONTES DE ENERGIA PRIMáRIAS EM USINAS DE AçO INTEGRADAS". Método e usina de aço integrada em que, em lugar de usar gases de forno de coque, gases de conversor e gases de topo de alto-forno disponíveis como combustível para geração de energia ou outras finalidades de aquecimento, esses gases são mais eficientemente utilizados como agentes químicos para redução direta de minérios de ferro produzindo DRI. DRI é carregado em alto-fornos aumentando a produção de aço em bruto, sem aumentar as capacidades da instalação de forno de coque e altos-fornos, sem mudanças na qualidade do aço em bruto, ou se a taxa de produção for mantida, o consumo específico de combustíveis fósseis é reduzido significativamente. A utilização de energia fóssil primária de acordo com a invenção também reduz as emissões específicas de CO~ 2~ por tonelada de aço em bruto. A emissão específica de CO~ 2~ em usinas integradas convencionais é cerca de 1,6 toneladas de CO~ 2~ por tonelada de aço em bruto.
