  Verfahren zum Trocknen von Brennstoffen. 



   Im Stammpatent Nr. 121405 ist ein Verfahren zum Trocknen von Brennstoffen beschrieben, bei dem das durch Heissdampfkreislauf vollständig getrocknete, hocherhitzte Trockengut entweder dadurch gekühlt wird, dass es unter Sattdampf gesetzt wird, der sich am Gut überhitzt und ihm dadurch Wärme entzieht, oder dadurch, dass durch Druckerniedrigung nach der praktisch vollständigen Entfernung des Wassers nun die im Trockengut gebildeten flüchtigen Ballaststoffe teilweise verdampfen und dadurch dem Trockengut Verdampfungswärme entziehen. 



   Gemäss der vorliegenden weiteren Ausgestaltung dieser Erfindung wird unter Beibehaltung der sonstigen Merkmale des Verfahrens nach dem Stammpatent der Heissdampf mit kleinen periodischen Druckschwankungen von etwa einer halben Atmosphäre angewendet, die sich kurzzeitig wiederholen sollen. Es wird hiedurch erreicht, dass der Heissdampf nicht nur die Aussenhaut der Kohle umspült und diese erwärmt, sondern jeweils bei der Drucksteigerung auch Gelegenheit hat, in die Poren derselben einzudringen. Hiedurch wird die Stückfestigkeit der ausgebrachten Kohle weiter verbessert und von der Regelung der Temperaturdifferenz zwischen Kohle und Heissdampf weitgehend unabhängig gemacht.

  Process for drying fuels.



   The parent patent no. 121405 describes a process for drying fuels in which the highly heated dry goods, which have been completely dried by the superheated steam cycle, are either cooled by placing them under saturated steam, which overheats the goods and thereby removes heat from them, or by that by lowering the pressure after the practically complete removal of the water, the volatile dietary fibers formed in the dry material now partially evaporate and thereby withdraw heat of vaporization from the dry material.



   According to the present further embodiment of this invention, while maintaining the other features of the method according to the parent patent, the superheated steam is used with small periodic pressure fluctuations of about half an atmosphere, which are intended to be repeated briefly. This ensures that the superheated steam not only flows around the outer skin of the coal and heats it, but also has the opportunity to penetrate into the pores of the same as the pressure increases. This further improves the lump strength of the coal discharged and makes it largely independent of the regulation of the temperature difference between coal and superheated steam.
