Abstract

EN EL FILTRADO DE GAS A ALTA TEMPERATURA (POR EJ. MAYOR DE 400 (GRADOS) C) Y A ALTA PRESION (POR EJ. MAYOR DE 5 BAR) -TAL COMO EL PRODUCIDO POR LA GASIFICACION O COMBUSTION DE LECHO FLUIDO A PRESION DEL CARBON- A MENUDO SE ACUMULAN PARTICULAS SOBRE LOS ELEMENTOS DE SOPORTE PARA LOS FILTROS, Y SOBRE LAS ESTRUCTURAS CIRCUNDANTES. ESTA DEPOSICION DE PARTICULAS PUEDE DAÑAR LOS ELEMENTOS DEL FILTRO, O REDUCIR GRANDEMENTE SU EFECTIVIDAD. ESTE PROBLEMA SE ELIMINA LIMPIANDO AUTOMATICAMENTE DE FORMA PERIODICA LAS SUPERFICIES DE SOPORTE Y/O CIRCUNDANTES DE LOS FILTROS, DIRIGIENDO CORRIENTES DE GAS A ALTA PRESION A LAS SUPERFICIES DE SOPORTE Y/O CIRCUNDANTES. TAMBIEN PUEDEN SUFRIR UN LAVADO DE SENTIDO INVERSO CON GAS COMPRIMIDO, SEGUN LA FORMA CONVENCIONAL, AL MISMO TIEMPO QUE, O EN MOMENTOS DIFERENTES DE, EL MOMENTO EN EL QUE SE LIMPIAN LAS ESTRUCTURAS DE SOPORTE Y/O CIRCUNDANTES. PUEDEN MONTARSE CONDUCTOS CON BOQUILLAS DIRECTAMENTE SOBRE LAS SUPERFICIES DE SOPORTE Y/O CIRCUNDANTES Y SE CONECTAN MEDIANTE UN TUBO CON UNA VALVULA AUTOMATICAMENTE CONTROLADA A UNA FUENTE DE FLUIDO A ALTA PRESION
