Abstract

EN UN PRECIPITADOR ELECTROSTATICO PARA LIMPIAR LOS GASES DE COMBUSTION DE PLANTAS INDUSTRIALES, QUE CONSTA DE UNA O MAS SECCIONES DE PRECIPITACION (7) ALIMENTADAS POR FUENTES DE CORRIENTE CONTINUA DE ALTA TENSION SEPARADAS TRADICIONALMENTE O INTERMITENTES, LA DESCARGA EN CORONA EN LA CAPA DE POLVO PRECIPITADA DURANTE EL PROCESO DE LIMPIEZA SOBRE LAS PLACAS ELECTRONEGATIVAS, SE DETECTA PERIODICAMENTE AUMENTANDO LA CORRIENTE DEL PRECIPITADOR EN CADA FUENTE DE ALTO VOLTAJE DE CORRIENTE CONTINUA HASTA QUE TIENE LUGAR LA DESCARGA DISRUPTIVA. TRAS ESTA (F), POSIBLEMENTE UN PERIODO DE BLOQUEO (B) (EN CASO DE QUE NO EXISTA DESCARGA DISRUPTIVA), EL VALOR MINIMO (U2MIN.U3MIN) DEL VOLTAJE DEL PRECIPITADOR SE COMPARA CON EL EXISTENTE (U0MIN) ANTES DE LA DESCARGA DISRUPTIVA, CORRIGIENDOSE EL ULTIMO VALOR POR UN FACTOR SELECCIONADO (K) DE SENSIBILIDAD DE DETECCION.
