Abstract
a presente invenção refere-se a um método para soprar pneumaticamente um agente de redução de substituição em pó em um reator de gaseificação em um método de fluxo denso por meio de um gás de transporte ou através de uma ventaneira (7) em um alto-forno de tal modo que o agente de redução de substituição é gaseificado em uma reação de gaseificação. o gás de transporte compreende um gás combustível cujos constituintes ou os seus constituintes de oxidação estão pelo menos parcialmente envolvidos na reação de gaseificação.
