Abstract

SISTEMA DE CONTROL DE LA TEMPERATURA PARA RECALENTADOR DE GENERADOR DE VAPOR POR COMBUSTIBLE FOSIL TIPO TAMBOR O SEPARADOR, QUE PRODUCE UNA SEÑAL DE AVANCE (F2C) QUE SE ADAPTA CONTINUAMENTE A LOS CAMBIOS EN LAS VARIABLES DEL SISTEMA PARA AJUSTAR LA ENTALPIA (H3) DEL VAPOR QUE PENETRA EN EL RECALENTADOR PARA CAMBIAR LA ABSORCION DE CALOR EN EL MISMO DE ACUERDO CON CAMBIOS EN LAS VARIABLES DEL SISTEMA Y MANTENER ASI UNA ENTALPIA CONSTANTE (H4) DEL VAPOR DESCARGADO DE DICHO RECALENTADOR. EL SISTEMA GENERA (27,31) UNA SEÑAL DE RETORNO EN RESPUESTA A LOS CAMBIOS EN LA TEMPERATURA (T4) DEL VAPOR DESCARGADO DEL RECALENTADOR (1) PARA VOLVER A AJUSTAR LA ENTALPIA (H3) DEL VAPOR QUE PENETRA EN EL RECALENTADOR A FIN DE MANTENER LA TEMPERATURA (T4) DEL VAPOR DESCARGADO DEL RECALENTADOR A UN VALOR DE ROCIO PREDETERMINADO (29).
