Abstract

Un parámetro clave en la operación segura de un sistema quemador, es la señal que se proporciona por el detector de flama que se emplea para asegurar que la flama se presenta cuando el combustible circula a la cámara de combustión del sistema. Una vez que se establece la operación de estado estable de sistema quemador, ya sea en fase de reposo o una fase no reposo, el nivel de señal de detector de flama normalmente está a un desplazamiento substancial desde el nivel umbral que determina si la flama se juzga presente o no. En ocasión la operación de detector de flama puede deteriorarse, el detector puede quedar desalineado, o las condiciones de aplicación pueden cambiar, cualquiera de los cuales puede resultar en un nivel de señal de flama durante la operación de estado estable que esta más cerca al nivel umbral que lo esperado. La función de ésta invención consiste en probar periódicamente y detectar éste nivel de señal fuera de rango desde el detector de flama. Cuando el sistema esté en una operación de reposo y no está presente flama, la invención involucra verificar si el nivel de señal de flama está dentro del rango definido por un bajo nivel marginal y el nivel umbral. Cuando el sistema está en una fase operacional en donde se espera la flama, la invención involucra verificar si el nivel de señal de flama está dentro de un rango definido por un alto nivel de margen y el nivel umbral. En caso de que cualquier verificación detecte ésta condición insatisfactoria, se proporciona una señal indicando ésta condición anormal. De preferencia, la condición anormal se emplea para controlar el destello de una lámpara indicadora, rápido durante la fase de reposo si el nivel de señal de flama es demasiado cercano al nivel umbral y más lentamente si el nivel de señal de flama está demasiado cercano al nivel umbral mientras que la flama está presente. También es posible el emplear dos lámparas diferentes para los indicadores.
