Abstract

RECICLADO DE CENIZAS VOLANTES PARA REDUCIR LAS EMISIONES DE GASES TOXICOS. SE DESCRIBE UN METODO PARA ELIMINAR LOS COMPUESTOS TOXICOS DE LAS EMISIONES GASEOSAS PROCEDENTES DE RESIDUOS MUNICIPALES SOLIDOS INCINERADOS EN UNA CAMARA DE COMBUSTION (11) EN EL CUAL LAS CENIZAS VOLANTES PRODUCIDAS POR EL PROCESO DE INCINERACION SE UTILIZAN PARA ABSORBER TOXINAS Y SE RECICLAN A LA CAMARA DE COMBUSTION (11), LO QUE DESTRUYE LAS TOXINAS ABSORBIDAS Y REGENERA LAS CENIZAS VOLANTES PARA UNA ABSORCION SUPLEMENTARIA DE TOXINAS.
