Abstract

"QUEIMADOR A GáS". Um micro queimador a gás é provido que gera uma chama pré-misturada estável, a qual produz pouca ou nenhuma fuligem ou hidrocarbonetos não queimados. O queimador a gás inclui uma entrada de combustível, bocal, câmara de oxigenação com pelo menos uma entrada de ar, uma câmara de mistura tendo uma parede interna troncónica, pelo menos uma barreira permeável e um retentor de chama. O queimador a gás mistura perfeitamente combustível e ar que entrou para formar uma mistura quase estequiométrica antes da combustão. O queimador a gás mistura o combustível e ar de modo tão perfeito que ele requer uma taxa de fluxo de combustível menor do que de outra maneira seria necessária para produzir uma chama pré-misturada estável. O queimador a gás pode incluir um tubo de chama opcional no qual uma chama é contida e seq³estrada do ar que se difunde.
