Abstract

a presente invenção refere-se a um queimador, particularmente queimador low-nox-, para gerar uma chama pela combustão de um combustível, compreendendo: um azulejo (15, 15a, 15b) circundando uma abertura (2, 2a, 2b) do azulejo (15, 15a, 15b) se estendendo ao longo de um eixo do queimador (12), o azulejo (15, 15a, 15b) ainda compreendendo um lado da frente (20) e um lado de trás (21) voltado a partir do lado da frente (20), em que o lado de trás (21) compreende uma entrada de ar (10, 10a, 10b) conectada à dita abertura para alimentação de ar (a, a', a") na dita abertura (2, 2a, 2b), e em que o dito lado da frente (20) compreende uma saída de descarga (9, 9a, 9b) conectada à dita abertura (2, 2a, 2b) para descarregar uma chama (30) gerada pelo queimador (1) em uma área circundante (s), e em que o azulejo (15, 15a, 15b) ainda compreende uma parte interna (22) voltada para a dita abertura (2, 2a, 2b), como também uma parte externa (23) voltada a partir da dita abertura (2, 2a, 2b). de acordo com a invenção, o queimador (1) ainda compreende pelo menos um maçarico de oxigênio (5) se estendendo ao longo do eixo do queimador (12) em um primeiro recesso (17) do dito azulejo (15, 15a, 15b), o pelo menos um maçarico de oxigênio (5) tendo um bico de ejeção (6) em uma região terminal do pelo menos um maçarico de oxigênio (5), para ejetar oxigênio (o), particularmente de tal modo que o oxigênio (o) é primeiro ejetado em uma região de gás combustível mais frio (31) circundando a chama relativamente mais quente (30) gerada pelo queimador (1). além disso, a invenção se refere a um método para gerar uma chama (30).
