Abstract

"GRUPAMENTO DE TUBULAçãO VENTURI, E QUEIMADORES E MéTODOS EMPREGANDO ESTE GRUPAMENTO". Uma disposição de queimadores inclui um grupamento de venturis, incluindo um pluralidade de venturis, dispostos para um fluxo paralelo. A disposição de múltiplos venturis utilizando combustível pressurizado como fluido indutor para indução de um fluxo de ar, possibilita a provisão de uma mistura preliminar ultra-escassa em combustível de combustível e ar. Uma tubulação central de queimador, que se estende para o exterior, para além da extremidade de fornecimento de uma extremidade de queimador primária e engastando um injetor de capacidade relativamente pequena a uma distância substancial da extremidade de fornecimento da extremidade de queimador, possibilitando a expansão e retardamento da mistura ultra-escassa em combustível, de tal forma que sua velocidade linear não exceda a velocidade de chama da mistura, anterior à chama do injetor espaçado. Um defletor pode ficar posicionado de forma adjacente ao injetor para auxílio na estabilização da chama, após o processo de expansão e de retardamento ter sido completado.
