Abstract

EL DISPOSITIVO DE CONTROL CONSTA DE UN TERMOPAR (15) QUE DETECTA LA TEMPERATURA DEL CATALIZADOR (10) Y DIRIGE UN DISPOSITIVO DE CONTROL ELECTRONICO (6) QUE POR TURNO CONTROLA UN DISPOSITIVO DE IGNICION (12, 13) Y UNA VALVULA (5) QUE SUMINISTRA GAS AL QUEMADOR (1). DURANTE UNA PRIMERA FASE OPERACIONAL (T{SUB 0}-T{SUB 2}), DICHA VALVULA ES INDUCIDA A CERRARSE CUANDO LA TEMPERATURA DEL CATALIZADOR (10) SE ELEVA A UN VALOR (A) POR ENCIMA DE UN VALOR DE TEMPERATURA PREDETERMINADA (T) AL QUE LA REACCION DEL CATALIZADOR SE DISPARA; ADEMAS, DICHA VALVULA (5) ES INDUCIDA A ABRIRSE DE NUEVO CUANDO LA TEMPERATURA DEL CATALIZADOR (10) DECRECE A UN VALOR PREDETERMINADO (B) INFERIOR AL VALOR (T + A), EN DONDE B < A. COMO RESULTADO, LA LLAMA CATALITICA DEL QUEMADOR PUEDE HACER IGNICION ESPONTANEAMENTE, SIN QUE HAYA NINGUNA NECESIDAD DE QUE EL DISPOSITIVO DE IGNICION SEA OPERADO UNA VEZ MAS.THE CONTROL DEVICE CONSISTS OF A THERMOCOUPLE (15) THAT DETECTS THE CATALYST TEMPERATURE (10) AND DIRECTS AN ELECTRONIC CONTROL DEVICE (6) THAT IN TURN CONTROLS AN IGNITION DEVICE (12, 13) AND A VALVE (5) THAT SUPPLIES GAS TO THE BURNER (1). DURING A FIRST OPERATIONAL PHASE (T {SUB 0} -T {SUB 2}), SUCH VALVE IS INDUCED TO CLOSE WHEN THE CATALYST TEMPERATURE (10) RISES TO A VALUE (A) ABOVE A DEFAULT TEMPERATURE VALUE ( T) TO WHICH THE CATALYST'S REACTION IS TRIGGERED; IN ADDITION, SUCH VALVE (5) IS INDUCED TO OPEN AGAIN WHEN THE TEMPERATURE OF THE CATALYST (10) DECREASES A DEFAULT VALUE (B) LESS THAN THE VALUE (T + A), WHERE B <A. AS A RESULT, THE CATALYTIC FLAME THE BURNER CAN MAKE IGNITION SPONTANEOUSLY, WITHOUT ANY NEED FOR THE IGNITION DEVICE TO BE OPERATED ONCE AGAIN.
