Abstract

SE INTRODUCE AIRE MEDIANTE UN CONDUCTO (36) EN EL SEPARADOR CICLONICO (18) EN SENTIDO OPUESTO AL DEL FLUJO DE GASES DE COMBUSTION Y SOLIDOS ARRASTRADOS. EL AIRE ARRASTRA UNA PARTE DE LOS SOLIDOS FINOS Y LOS PASA A TRAVES DEL SEPARADOR (18) A UNA ZONA DE RECUPERACION DE CALOR (24) PARA REDUCIR LA CANTIDAD DE SOLIDOS DEL SISTEMA DE CIERRE (28,30,32) EN LA MEDIDA NECESARIA.
