Abstract

Se descubre un quemador que tiene una cámara del quemador con paredes retenedoras de calor altamente aisladas y unas series de mezcladoras fuera de centro localizados en un extremo del mismo. Se hace ignicion a una mezcla de concentracion uniforme de gas/aire para un 50% de combustible adicional sobre el límite pobre de inflamabilidad que viene desde los tubos mezcladores, dentro de la cámara del quemador debido a la recirculacion del gas de combustion y el aire de regreso al extremo de la cámara del quemador sobre la temperatura de autoignicion de la mezcla. La mezcla en particular descubierta utiliza proporciones de equivalencia de .55-.7. Con el quemador presente, el oxidante y el combustible se abastecen respectivamente a cada mezclador por los plenos comunes respectivos de combustible y oxidante. En esta manera, el combustible y el oxidante son mezclados cerca del punto de combustion, mejorando la seguridad y permitiendo la construccion de quemadores más grandes.
