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.GAS BURNER STEAM GENERATOR. In the case of a steam generator gas burner (1) for burning low calorific gases comprising a central air pipe (2), a gas pipe (6) arranged coaxially around the central air pipe (2) ) to form a gas flow cross-section (5), in particular a circular gas flow cross-section, and at least one further pipe element (8) coaxially disposed around the gas pipe (6) to form a cross-section. secondary air flow cross-section (7), in particular a circular secondary air flow cross-section, where the first agitators (9) disposed in the gas flow cross-section (5) are intended to provide a solution that renders It is possible to adapt a steam generator gas burner to varying properties of the fuel gas, in particular a fluctuating calorific value, while considering its ignition intensity. This is accomplished by the first adjustable shakers (9).
