Abstract

Patente de Invenção: <B>"MéTODO E DISPOSIçãO PARA OTIMIZAR A OXIDAçãO DURANTE A QUEIMA DE COMBUSTìVEIS GASOSOS E LìQUIDOS"<D>. Um método e uma disposição para reduzir as emissões de óxidos de nitrogênio em um aparelho de combustão equipado com uma fornalha tubular. O método compreende queimar os gases odoríficos inicial subestequiométrica, e subseq³entemente fornecer um ar adicional para a fornalha (3) na sua direção tranversal de um tal modo que a proporção de ar final fique acima de 1. A disposição compreende um duto de ar adicional (7) o qual se estende para a fornalha da caldeira e do qual o ar adicional é fornecido para a fornalha (3) na direção transversal da fornalha (3).
