Abstract

APARELHO PARA SUPRIMENTO DE SOPRO PARA UM ALTO-FORNO E MÉTODO DE SUPRIMENTO DE SOPRO. A presente invenção refere-se a um aparelho para suprimento de sopro para um alto-forno (1) que compreende uma pluralidade de trocadores de calor de sopro quente (4, 5, 6), sendo que cada trocador de calor compreende uma entrada de sopro frio, uma entrada de combustível, uma entrada de suprimento de ar, uma saída de sopro quente e uma saída de gás residual; e uma unidade de recuperação de calor residual (30) conectada a um suprimento de combustível, a entrada de combustível de trocador de calor e a entrada de sopro frio. As saídas de gás residual de trocador de calor são conectadas às entradas de sopro frio, por meio das quais o gás residual de trocador de calor de um trocador de calor (5) é suprido através da unidade de recuperação de calor residual, como sopro frio em outro trocador de calor (4).
