Abstract

sistema de combustão com emissão ultrabaixa de nox e método de mistura rápida de combustível. trata-se de sistema de combustão (10) que utiliza método de mistura rápida de gás combustível com ar de combustão de a obter mistura intensa de fluxo de ar com fortes componentes rotacionais com uma pluralidade de jatos de gás descarregada para esse fluxo. a montagem de sistema de combustão (10) inclui um corpo externo dotado de uma entrada de ar e flanges de montagem. o corpo externo (12) é conectado com o elemento de saída cônica (18) e ainda com combustor de formato cilíndrico (20). o sistema de combustão (10) também inclui o conjunto de combustível compreendido por dois tubos coaxiais (24) e (26) com aletas (42) curvas de swirl e injetores de gás (48). essa montagem é colocada dentro do corpo externo (12) ao longo do eixo do queimador com as aletas (42) posicionadas próximo à entrada do elemento cônico (18). o sistema de combustão opera empregando um método de mistura rápida, com os jatos de gás combustível injetados e regularmente distribuídos no fluxo de ar de combustão com componentes rotacionais de alta intensidade.combustion system with ultra-low nox emissions and rapid fuel mixing method. This is a combustion system (10) that uses a method of rapidly mixing fuel gas with combustion air to obtain an intense mixture of air flow with strong rotational components with a plurality of gas jets discharged into this flow. The combustion system assembly (10) includes an outer body provided with an air inlet and mounting flanges. the external body (12) is connected to the conical output element (18) and also to the cylindrical-shaped combustor (20). the combustion system (10) also includes the fuel assembly comprised of two coaxial tubes (24) and (26) with swirl curved fins (42) and gas injectors (48). this assembly is placed within the outer body (12) along the burner axis with the fins (42) positioned near the inlet of the conical element (18). The combustion system operates employing a rapid mixing method, with jets of fuel gas injected and regularly distributed in the combustion air flow with high-intensity rotational components.
