Abstract

UN METODO Y APARATO PARA REDUCIR LA PRODUCCION DE EMISION DE GASES NOCIVOS MIENTRAS SE PRECALIENTA CONTINUAMENTE UNA MEZCLA DE MATERIALES CARGADOS DE DESECHOS SOPORTADOS POR CADENA A UN HORNO ELECTRICO QUE HACE ACERO OPERADO CON DESCARGA GASEOSA DEL HORNO, QUE INCLUYE PROVISION PARA COMBUSTION CONTROLADA DENTRO DE LA CAMARA DE PRECALENTAMIENTO. GASES ELIMINADOS SON ENTONCES TRATADOS POR INCINERACION TERMICA DE MATERIAL DE COMBUSTIBLE RESIDUAL ANTES DE LIBERARLOS A LA ATMOSFERA PARA ASEGURAR QUE NO SON EMITIDOS GASES NOCIVOS.
