Abstract

QUEIMADOR A GáS GERADOR DE VAPOR. No caso de um queimador a gás gerador de vapor (1) para queimar gases de baixo valor calorífico, que compreende um tubo de ar central (2), um tubo de gás (6) disposto coaxialmente ao redor do tubo de ar central (2) para formar uma seção transversal de fluxo de gás (5), em particular uma seção transversal circular de fluxo de gás, e pelo menos mais um elemento tubo (8) disposto coaxíalmente ao redor do tubo de gás (6) para formar uma seção transversal de fluxo de ar secundário (7), em particular uma seção transversal circular de fluxo de ar secundário, onde os primeiros agitadores (9) dispostos na seção transversal de fluxo de gás (5),destina-se a fornecer uma solução que torne possível adaptar um queimador a gás gerador de vapor para propriedades variáveis do gás combustível, em particular um valor calorífico flutuante, enquanto se considera a respectiva intensidade de ignição. Isto é realizado pelos primeiros agitadores (9) dispostos de modo ajustável.
