Abstract

MÉTODO PARA CONVERTER UMA INSTALAÇÃO DE ALTO-FORNO. A invenção refere-se a um método para converter uma instalação de alto-forno (1), que compreende inicialmente pelo menos um alto-forno (10, 50), uma pluralidade de fogões originais (31-36) adaptados para gerar jato quente, um sistema de fornecimento de gás de topo (11, 51) para fornecer gás de topo de pelo menos um alto-forno (10, 50) para cada fogão original (31-36), um sistema de fornecimento de jato frio (14) para fornecer jato frio para cada fogão original (31-36), um sistema de fornecimento de jato de calor (15, 55) para fornecer jato quente de cada fogão original (31-36) para um sistema de injeção de jato quente (16, 56), que é adaptado para injetar gás em pelo menos um alto-forno (10, 50) em um nível de ventaneira (10.1, 50.1). De modo a permitir uma conversão eficiente de uma instalação de alto-forno para utilização de gás de síntese, a invenção prevê que o método compreende: - ao operar os fogões originais (31-36) para gerar jato quente, construir pelo menos um fogão a syngas (40, 41), adaptado para produzir um syngas reformando uma combinação de gás de um gás industrial contendo CO2 e um gás combustível contendo hidrocarbonetos, e construir um sistema de fornecimento de syngas (18) adaptado para conectar pelo menos um fogão a syngas (40, 41) a pelo menos um alto-forno (10, 50); - conectar um primeiro fogão a syngas (40) ao sistema de fornecimento de gás de topo (11, 51), ao sistema de fornecimento de jato frio (14) e ao sistema de fornecimento de jato de calor (15, 55) e operar o primeiro fogão a syngas (40) para geração de jato quente; - desconectar um primeiro fogão original (31) a partir do sistema de fornecimento de gás de topo (11, 51), do sistema de fornecimento de jato frio (14) e do sistema de fornecimento de jato de calor (15, 55); - converter o primeiro fogão original (31) para adaptá-lo para produzir syngas, se necessário substituindo seu revestimento refratário e/ou o suporte de seu revestimento refratário e/ou seus componentes mecânicos; - conectar o primeiro fogão original (31) ao sistema de fornecimento de gás de topo (11, 51); - desconectar o primeiro fogão a syngas (40) a partir do sistema de fornecimento de jato frio (14) e do sistema de fornecimento de jato de calor (15, 55), conectar o primeiro fogão original (31) e o primeiro fogão a syngas (40) a um sistema de fornecimento de combinação de gás (19) para fornecer a combinação de gás e através do sistema de fornecimento de syngas (18) para pelo menos um alto-forno (10, 50); e - operar o primeiro fogão original (31) e o primeiro fogão a syngas (40) para produzir syngas e fornecer o syngas ao pelo menos um alto-forno (10, 50) através do sistema de fornecimento de syngas (18).
