Abstract

LOS HUMOS NOCIVOS QUE SALEN DE LA CAMARA DEL HOGAR SECO (112) DE UN HORNO DE RECUPERACION DE METALES (102) SON ALIMENTADOS EN UN INCINERADOR (106) DONDE SE QUEMAN A ALTA TEMPERATURA CON OXIGENO. EL GAS DE ESCAPE LIMPIO, CALIENTE SE INTRODUCE EN LA CAMARA DE BAÑO (11) DEL HORNO (102). ESTA DISPOSICION AHORRA TIPICAMENTE UN 60% DEL COSTE DE COMBUSTIBLE. ADEMAS, PUESTO QUE LOS HUMOS SON RECICLADOS, LA EMISION DE ESCAPE A LA ATMOSFERA SOLO REFLEJA AL ENTRADA DE COMBUSTIBLE Y OXIGENO. ESTO PUEDE SER CASI UNA OCTAVA PARTE DE UNA PLANTA CONVENCIONAL CON LO QUE SE REDUCE LA TAREA DE FILTRADO Y/O DEPURACION Y EL TAMAÑO DE LA CHIMENEA. POR TANTO ESTA DISPOSICION SUPONE UNA SERIE DE VENTAJAS PARTICULARES PARA LA CONSERVACION DEL COMBUSTIBLE Y LA CONSERVACION DEL MEDIO AMBIENTE. PERMITE QUE SE RECICLEN LOS METALES EN UNA INSTALACION QUE PRODUCE POCA CONTAMINACION Y QUE UTILIZA EL CALOR DEL MATERIAL DE DESECHO PARA CONSERVAR EL COMBUSTIBLE.
