Abstract
"SISTEMA DE AQUECIMENTO DE AR PARA ALTOS-FORNOS". A presente invenção de um sistema de aquecimento do ar para altos-fornos que consiste de pré-aquecimento do ar em um regenerador do tipo "glendon" antes do aquecimento final em um regenerador do tipo "cowper", proporciona uma economia de combustível de 10% e uma substituição de outros 9% de combustível granulado por finos."AIR HEATING SYSTEM FOR BLAST OVENS". The present invention of an air heating system for blast furnaces, which consists of preheating the air in a "glendon" regenerator before final heating in a "cowper" regenerator, provides a fuel economy of 10 % and a replacement of another 9% of granulated fuel for fines.
