Abstract

SISTEMA DE SEGURIDAD (10) DE LLAMA QUE UTILIZA UN MICROORDENADOR (16), EL CUAL RESPONDE A LA SEÑAL DE LLAMA (22) PROPORCIONADA POR UNA CADENA (20) DE AMPLIFICACION DE LLAMA NORMAL Y UN CONVERTIDOR (32) ANALOGICO-DIGITAL. UN CIRCUITO DE PROTECCION, COMO CIRCUITO (45) DETECTOR DE SEÑAL DE LLAMA SOBRANTE, ANALIZA LA SEÑAL ANALOGICA SUMINISTRADA AL CONVERTIDOR ANALOGICO-DIGITAL. EN EL CASO DE QUE EL MICROORDENADOR (16) NO PUEDA CERRAR LA VALVULA PRINCIPAL DE COMBUSTIBLE, EL CIRCUITO DETECTOR DE LLAMA SOBRANTE SE HACE OPERATIVO PARA DESACTIVAR UNA PARTE (62) DE UN CIRCUITO EN SERIE (62,36) QUE INCLUYE EL RELE (40) DE LA VALVULA PRINCIPAL (11) DE COMBUSTIBLE.
