Abstract

PROCEDIMIENTO DE FUNCIONAMIENTO DE UNA CENTRAL ELECTRICA ALIMENTADA CON UN COMBUSTIBLE NECESITADO DE SECADO, ESPECIALMENTE CON LIGNITO, LA CUAL PRESENTA AL MENOS UNA CALDERA, UNA CHIMENEA DE CONVECCION DISPUESTA A CONTINUACION DE DICHA CALDERA, AL MENOS UN MOLINO CON ALIMENTADOR PARA EL COMBUSTIBLE NECESITADO DE SECADO Y AL MENOS UNA TURBINA DE VAPOR. LA CORRIENTE DE GAS DE ESCAPE DE LA CALDERA QUE SALE DE LA CHIMENEA DE CONVECCION CON LA TEMPERATURA DE SALIDA DE ESTA ULTIMA ES ENFRIADA HASTA UNA TEMPERATURA DE DESEMPOLVADO Y HECHA PASAR POR UNA INSTALACION DE DESEMPOLVADO. EL COMBUSTIBLE NECESITADO DE SECADO ES SECADO CON GAS DE SECADO QUE SE HACE PASAR POR UN INTERCAMBIADOR DE CALOR QUE ESTA DISPUESTO EN RELACION DE INTERCAMBIO DE CALOR CON LA CORRIENTE DE GAS DE ESCAPE DE LA CALDERA.
