Abstract

SE SUMINISTRA UN METODO DE COMBUSTION DE LECHO LIQUIDO PARA QUEMAR RESIDUOS UTILIZANDO UN HORNO DE LECHO LIQUIDO SIN SER AFECTADO POR LA FLUCTUACION DE LA CANTIDAD NI CALIDAD DE RESIDUOS ALIMENTADOS AL HORNO, POR LO QUE PREVIENE LA DESCARGA DE CO FUERA DEL HORNO. ESTE HORNO COMPRENDE UN NUMERO DE TUBOS DIFUSORES DE AIRE (5) PARA ALIMENTAR UN PRIMER AIRE A LECHO LIQUIDO (3), SITUADOS PARALELAMENTE UNO AL OTRO EN EL FONDO DEL LECHO LIQUIDO (3), Y UNA PARTE DE ESPACIO LIBRE FORMADO ENCIMA DEL LECHO (3) PARA QUEMAR MATERIAS NO QUEMADAS CON UN AIRE SECUNDARIO, TENIENDO DICHO TUBO (5) DIFUSOR DE AIRE UN NUMERO DE BOQUILLAS SUMINISTRADAS A LO LARGO DEL EJE DEL TUBO Y UN PRIMER MEDIO DE CONTROL DEL AIRE INCLUYENDO UN HUMEDECEDOR DE APERTURA Y CIERRE (7) PARA CONTROLAR LA CALIDAD DEL AIRE A SER ALIMENTADO Y EL METODO SE LLEVA A CABO ALIMENTANDO DICHO AIRE PRIMERO EN EL LECHO (3) A TRAVES DE DICHOS TUBOS (5) UNO DESPUES DEL OTRO DE ACUERDO CON UN PATRON PREDETERMINADO DE APERTURA Y CIERRE POR MEDIO DE DICHOS MEDIOS DE CONTROL DE AIRE PRIMARIO PARA QUE EL NIVEL DE LA CANTIDAD DE AIRE UO A LA CANTIDAD MINIMA DE AIRE FLUIDO (UO/UMF) ESTE EN EL NIVEL DE 1,4 A 4 CUANDO DICHO HUMIDIFICADOR ESTE ABIERTO Y EN EL NIVEL DE 0,5 A 2 CUANDO DICHO HUMIDIFICADOR ESTE CERRADO Y EN INTERVALOS DE 1 A 10 SEGUNDOS, PREFERENTEMENTE DE 2 A 10 SEGUNDOS Y DE 10 A 100 SEGUNDOS RESPECTIVAMENTE.
