 entstehen, wurde zur Bekämpfung des   Kesselstoinanaatzes   verwendet, jedoch erfüllte dasselbe seinen Zweck nur so unvollkommen, dass es für die Praxis un verwendbar blieb. 



  Der Grund dieses mangelhaften Ergebnisses war darin zu suchen, dass die in den Kessel eingeführten Abwässer schwerer waren wie das Speisewasser. 



   Durch vielfache Versuche ist es gelungen, ein absolut sicher wirkendes Kesselsteinlösemittel herzustellen, indem zerkleinertes Holz, dem vor dem Verkochen   nater Druck   das Harz entzogen wurde, mit einer Natronlauge von nur 2% verkocht wird. Die zur Verwendung gelangenden Hölzer werden vor dem Verkochen zu Zellulose der Einwirkung von Dampf in einem Kessel ausgesetzt und darauf mit   trockener heisser   Luft weiter behandelt. Durch diese Behandlung mit Dampf und der darauf folgenden mit trockener

   Das Verkochen erfolgt in einem mit Rührwerk versehenen Kessel unter einem   Druck-   von 14 Atm. mit 2%iger Natronlauge, Nach etwa   zehnstündiger   Kochdauer ist   alle   Holz zersetzt und es ist ein Präparat entstanden, dass allen Anforderungen eines sicher wir-    kenden   Kesselsteinlösemittels entspricht. 



   Die Wirkungsweise dieses Lösemittels ist nun, entgegen den bekannten, nicht chemisch, sondern mechanisch. Weil das Mittel das gleiche spezifische Gewicht wie Wasser

Die Folge hievon ist, dass der Kesselstein abgesprengt und das Kesselblech mit einer dünnen Isolationsschicht überzogen wird, die mit absoluter   Sicherheit eine Neubildung   des Kesselsteines verhindert. Durch Zusetzen des Lösemittels zum Kesselspeisewasser umhüllen die eingeführten Zelluloseteilchen, sobald neu zugeführtes Wasser in den Kessel tritt, die sich ausscheidenden Karbonate usw. mit einer mikroskopisch feinen Schicht, welche die Eigenschaft hat, die im Kesselwasser frei   schwabenden   Teile niederzuschlagen und dauernd daran haften zu bleiber.

 was used to combat the Kesselstoinanaatzes, but it only served its purpose so imperfectly that it was unusable in practice.



  The reason for this inadequate result was to be found in the fact that the waste water introduced into the boiler was heavier than the feed water.



   Through multiple attempts, it has been possible to produce an absolutely safe scale solvent by boiling shredded wood, from which the resin was removed before boiling under pressure, with a sodium hydroxide solution of only 2%. The woods that are used are exposed to the action of steam in a kettle before they are boiled into cellulose and then treated with dry, hot air. This treatment with steam and the subsequent one with a dry one

   The cooking takes place in a kettle equipped with a stirrer under a pressure of 14 atm. with 2% sodium hydroxide solution. After about ten hours of cooking, all the wood has decomposed and a preparation has been created that meets all the requirements of a safe scale solvent.



   The mode of action of this solvent is now, contrary to the known, not chemical, but mechanical. Because the agent has the same specific weight as water

 solid stone and the boiler plate. The consequence of this is that the scale is blasted off and the boiler sheet is covered with a thin layer of insulation, which with absolute certainty prevents the scale from forming again. By adding the solvent to the boiler feed water, the cellulose particles that have been introduced, as soon as the newly supplied water enters the boiler, envelops the carbonates, etc., with a microscopically fine layer, which has the property of depositing the parts floating freely in the boiler water and of sticking to them permanently .
