Abstract

queimador industrial e processo de combustão correlacionado a fornos de tratamento térmico. a presente invenção está correlacionada a um queimador de alta velocidade, tendo emissões de poluição bastante baixas, adequado para o processamento de fornos de tratamento térmico de uma carga em atmosfera livre. o queimador é capaz de produzir uma chama compacta e fina, com a peculiaridade de manter as emissões de nox em níveis bastante baixos em qualquer temperatura da câmara, e com qualquer excesso de ar de combustão. o queimador exige uma única entrada para o ar comburente e uma única entrada para o gás combustível.
