Abstract

Una caldera de doble combustible tiene aparato de distribucion de combustible acoplado a su seccion de quemador a traves de un regulador de presion y operativo para distribuir a la seccion del quemador, a partir de fuentes del mismo, una variable selectiva de (1) un primer combustible en una presion mayor que el establecimiento de regulacion de presion del regulador de presion, y (2) un segundo combustible a una presion menor que el establecimiento de regulacion de presion, el segundo combustible tiene un indice de Wobbe mayor que aquel del primer combustible. El primer combustible se hace fluir hacia la seccion del quemador mediante una linea de suministro de ramificacion en la cual la primera y segunda valvulas de dos posiciones de dos vias de dos posiciones electromecanicas se instalan en serie en orientaciones de flujo de normal opuestas para evitar con esto el contraflujo del segundo combustible en la fuente del primer combustible.
