Abstract
PROCESSO E USINA PARA A PRODUÇÃO E TRATAMENTO ADICIONAL DE GÁS COMBUSTÍVEL. A presente invenção refere-se à produção de gás combustível e à realização de um processo metalúrgico, materiais carbonáceos, por exemplo, carvão ou biomassa, reagidos com um gás contendo oxigênio em um primeiro estágio do processo para obter um gás combustível que contém monóxido de carbono, hidrogênio, óxido de carbono e/ou vapor, em que o gás combustível obtido é resfriado a uma temperatura de 300 a 600°C, preferivelmente 350 a 450°C, e subsequentemente submetido a uma separação de sólidos, e em que, em um segundo estágio do processo, o gás combustível é carregado a pelo menos um queimador do processo metalúrgico. O gás combustível da separação de sólidos é diretamente fornecido ao pelo menos um queimador do segundo estágio do processo, em que, após resfriamento, a temperatura do gás combustível é mantida dentro do intervalo de 300 a 600°C, preferivelmente 350 a 450°C, minimizando as perdas de calor e/ou fornecimento de calor.
