Abstract
a invenção se refere a um forno de loop com baixa nox para a fusão de vidro munido de um queimador aéreo que compreende um conduto de admissão de comburente que compreende 15 a 30 % de oxigênio em sua parede a montante, um conduto de recepção das fumaças de combustão em sua parede a montante, e um sistema de injeção sônica que compreende pelo menos um injetor de um jato de um gás com velocidade pelo menos igual a 80 % da velocidade sônica, dito injetor sônico, que desemboca na parede a montante ou que desemboca no conduto de recepção das fumaças de combustão, o dito injetor sônico injetando seu gás em contracorrente ao fluxo das fumaças de combustão que se dirige para o conduto de recepção das fumaças de combustão, assim como a um processo de preparação de vidro fundido que compreende a fusão de vidro no dito forno.
