Abstract

EL INDICE DE FLUJO VOLUMETRICO PARA LA ADICION DE UN AGENTE DE ACONDICIONAMIENTO DE GAS DE COMBUSTION, COMO ES EL TRIOXIDO DE SULFURO, ES ESTABLE MANTENIENDO EL DERIVADO DE LA POTENCIA DEL PRECIPITADOR ELECTROESTATICO RESPECTO DE INDICE DEL FLUJO DENTRO DE UN LIMITE DE OPERACION PRESELECCIONADO. EL DERIVADO DE LA POTENCIA DEL PRECIPITADOR RESPECTO DEL TIEMPO Y EL DERIVADO DEL INDICE DE FLUJO RESPECTO DEL TIEMPO SON MEDIDOS, Y A CONTINUACION LOS DERIVADOS SE DIVIDEN PARA DETERMINAR EL DERIVADO DE LA POTENCIA DEL PRECIPITADOR RESPECTO DEL INDICE DEL FLUJO. ESTE VALOR CALCULADO SE COMPARA CON UN LIMITE DE OPERACION PRESELECCIONADO. SI EL VALOR CALCULADO ES MAYOR QUE EL LIMITE DE OPERACION PRESELECCIONADO, EL INDICE DEL FLUJO DEL AGENTE ACONDICIONADOR AUMENTA. SI EL VALOR CALCULADO ES MENOR QUE EL LIMITE DE OPERACION PRESELECCIONADO, EL INDICE DEL FLUJO SE REDUCE, HASTA QUE SE ALCANZA UN VALOR DERIVADO CALCULADO DEL ESTADO FIJO DENTRO DEL LIMITE DE OPERACION.
