Abstract

Generador de turbulencias, con un interruptor de retroceso de llama integral, comprendiendo: Un primer monolito que comprende una pluralidad de primeros canales que se extienden a través del mismo, definidos los canales por paredes, presentando las paredes de los primeros canales superficies de extinción, teniendo cada uno de los primeros canales una entrada, una salida, una longitud y un diámetro hidráulico medio, con las entradas de los primeros canales determinando una cara aguas arriba, las salidas de los primeros canales determinando una cara aguas abajo; así como un segundo monolito que comprende una pluralidad de segundos canales, definidos por paredes, presentando las paredes de los segundos canales superficies de extinción, teniendo cada uno de los segundos canales una longitud y un diámetro hidráulico medio, con las entradas de los segundos canales determinando una cara aguas arriba, las salidas de los segundos canales determinando una cara aguas abajo, estando el primer monolitosituado espacialmente aguas arriba con respecto al segundo monolito, con una distancia de separación entre el primer monolito y el segundo monolito, cuya longitud es menor que la distancia de reformación de llamas, siendo la longitud de los primeros canales más la longitud de los segundos canales menor que la longitud de un canal individual del interruptor de retroceso de llama de un canal individual, y siendo la proporción entre el diámetro hidráulico medio de los primeros canales y el diámetro hidráulico medio de los segundos canales tal que una llama se extingue durante un evento de retroceso de llama, quedando desplazados los canales del primer monolito y los canales del segundo monolito, y presentando por lo menos uno de los canales del segundo monolito una orientación espacial tal que se imparte una turbulencia a un fluido, cuando pasa a través del mismo.
