La paja es uno de los residuos agr\u00edcolas m\u00e1s comunes, generados en cientos de millones de toneladas anualmente en todo el mundo. Su quema a cielo abierto provoca contaminaci\u00f3n del aire, p\u00e9rdida de fertilidad del suelo y riesgos para la salud de la poblaci\u00f3n.<\/p>\n\n\n\n

\u00bfPor qu\u00e9 torrefacci\u00f3n?<\/strong><\/strong><\/h3>\n\n\n\n

La torrefacci\u00f3n es un tratamiento t\u00e9rmico suave de la biomasa en condiciones anaer\u00f3bicas, a temperaturas entre 230\u202f\u00b0C y 300\u202f\u00b0C. Este proceso convierte la paja en biomasa torrefactada (torrefacto) con propiedades similares al carb\u00f3n f\u00f3sil, tales como:<\/p>\n\n\n\n

    \n
  • Mayor densidad y poder calor\u00edfico<\/li>\n\n\n\n
  • Hidrofobicidad (resistencia a la humedad)<\/li>\n\n\n\n
  • Buena capacidad de molienda<\/li>\n\n\n\n
  • Reducci\u00f3n del contenido de vol\u00e1tiles<\/li>\n<\/ul>\n\n\n\n

    El torrefacto puede utilizarse en calderas y hornos, e incluso mezclarse con carb\u00f3n f\u00f3sil sin necesidad de modificar los equipos existentes.<\/p>\n\n\n\n

    \u00bfPor qu\u00e9 briquetar antes de la torrefacci\u00f3n?<\/strong><\/strong><\/h3>\n\n\n\n

    Cuando se utiliza paja con una humedad aproximada del 10\u202f%, su densidad aparente es de unos 70\u202fkg\/m\u00b3, lo que limita considerablemente el rendimiento del reactor de pir\u00f3lisis. La formaci\u00f3n de briquetas o pellets a partir de la paja incrementa la densidad aparente hasta 350\u2013400\u202fkg\/m\u00b3, m\u00e1s de cinco veces, lo que mejora significativamente la conductividad t\u00e9rmica durante el proceso de torrefacci\u00f3n.<\/p>\n\n\n\n

    Etapas del proceso<\/strong><\/strong><\/h3>\n\n\n\n
      \n
    • Secado y trituraci\u00f3n<\/strong> \u2013 Reducci\u00f3n de la humedad y preparaci\u00f3n del material para el briqueteado<\/li>\n\n\n\n
    • Briquetado<\/strong> \u2013 Compresi\u00f3n de la paja en briquetas cil\u00edndricas densas, t\u00edpicamente de 32\u202fmm de di\u00e1metro y 30\u2013100\u202fmm de longitud<\/li>\n\n\n\n
    • Torrefacci\u00f3n<\/strong> \u2013 Tratamiento t\u00e9rmico del material en ambiente sin ox\u00edgeno a temperaturas finales de 230\u2013300\u202f\u00b0C<\/li>\n\n\n\n
    • Enfriado y envasado<\/strong> \u2013 El torrefacto se enfr\u00eda y se embala seg\u00fan las especificaciones del cliente<\/li>\n<\/ul>\n\n\n\n
      \"\"<\/figure>\n\n\n\n

      Ventajas del torrefacto de paja<\/strong><\/strong><\/h3>\n\n\n\n
        \n
      • Mayor densidad energ\u00e9tica<\/strong> \u2013 Gracias al aumento del contenido de carbono fijo<\/li>\n\n\n\n
      • Facilidad de transporte y almacenamiento<\/strong> \u2013 Por su menor volumen y propiedades hidrof\u00f3bicas<\/li>\n\n\n\n
      • Responsabilidad medioambiental<\/strong> \u2013 Reducci\u00f3n de emisiones de CO\u2082 y de la contaminaci\u00f3n<\/li>\n\n\n\n
      • Eficiencia econ\u00f3mica<\/strong> \u2013 Posibilidad de uso como combustible principal en calderas industriales<\/li>\n<\/ul>\n\n\n\n
