Metallurgical furnace with scrap metal preheater and dispenser

   
   

A Preheater-Steelmaking Furnace and closed loop Process System for semi-continuous melting of integrally preheated recycled or virgin ferrous charge, by using highly energy efficient combustion process of natural gas combusted by oxygen as the main heat source, after preheating of the cold charge, by fully exploiting thermal energies of the melting process off-gases, in a gas tight, low noise, ecologically friendly PSF with scant CO and drastically reduced CO.sub.2 in exhaust gases for semi-continuous, batch self-charging, sealed pairs of eccentrically rotating quasi cylindrical, permeable half drums hoppers creating separate preheating chambers.

Uma fornalha do Preheater-preheater-Steelmaking e um laço closed processam o sistema para o derretimento semi-continuous do pré-aquecido integralmente recycled ou a carga ferrosa virgem, usando altamente o processo eficiente da combustão da energia do gás natural combusted pelo oxigênio como a fonte de calor principal, depois que pré-aquecimento da carga fria, inteiramente explorando energias térmicas dos off-gases process de derretimento, em um ruído apertado, baixo do gás, em PSF ecologically amigável com CO scant e em CO.sub.2 dràstica reduzido em gáses de exaustão para semi-continuous, grupo quecarrega, pares selados excêntrica de girar meios os funis cilíndricos, permeable quasi dos cilindros que críam câmaras de pré-aquecimento separadas.
