Abstract

Dispositivo quemador que comprende un conjunto de tubos venturi consistente en una pluralidad de tubos venturi dispuestos para corrientes paralelas. La disposicion de venturis multiples que emplea combustible a presion como fluido inductor para inducir una corriente de aire, posibilita la provision de una premezcla de combustible y aire extrapobre en combustible. Hay un tubo central de quemador que se extiende hacia afuera, sobresaliendo del extremo de salida de un pico primario, sobre el que se monta una boquilla de capacidad relativamente pequena a una distancia substancial del extremo de salida del pico, permitiendo que la mezcla extrapobre en combustible se expanda y haga más lenta de manera que su velocidad lineal no exceda la velocidad de la llama de la mezcla antes de llegar a la llama de la boquilla. Es posible colocar un deflector adyacente a la boquilla para ayudar a estabilizar la llama luego de completado el proceso de expansion y reduccion de velocidad.
