Abstract

resumo processo e aparelho para melhoria da combustão de um combustível secundário em um forno rotativo a presente invenção se refere a um processo e a um aparelho para a melhoria da combustão de um combustível secundário (10) suprido em uma primeira corrente (7) em um forno rotativo (1), em que o forno rotativo (1) tem um conjunto de queimador (9), compreendendo um queimador principal (5) e uma pluralidade de canais de alimentação (16, 17, 18, 19, 20) para vários meios, dos quais um (19) é projetado para o suprimento de um combustível secundário (10), em particular na forma de partículas ou fragmentos em uma corrente de ar comprimido. de acordo com a invenção, uma lança de oxigênio tubular (12) para um gás rico em oxigênio, em particular, um oxigênio gasoso de grau técnico (11), ou um líquido rico em oxigênio, em particular, um oxigênio líquido de grau técnico (11), com um bocal inclinado (14) em sua extremidade, é disposto em ou sobre um canal de alimentação (20) do conjunto de queimador (9), por meio do que a lança de oxigênio (12) é levado para uma posição em que o oxigênio (11) emergindo a partir de um bocal (14) forma uma segunda corrente (8) que bate em uma primeira corrente (7) de combustível secundário. a presente invenção pode ser considerada para novas construções de conjuntos de queimador para fornos rotativos, mas principalmente serve para retroadaptação de conjuntos queimadores existentes, em que a maioria dos canais de alimentação está disponível, conforme requerido para inserção de uma lança de oxigênio na presente invenção. o envio direcionado de oxigênio gasoso ou líquido, ou de um gás enriquecido com oxigênio ou um gás liquefeito para um combustível secundário, pode melhorar significativamente o processo de combustão e, consequentemente, reduzir significativamente as emissões de exaustão, em particular, a emissão de monóxido de carbono.
