KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es ist ein Verfahren zur Entfernung von Kesselstein bekannt, bei dem durch Erhitzen der mit Kesselstein behafteten Kesselteile eine Dehnung dieser eisernen Teile herbeigeführt wird, der der Kesselstein nicht zu folgen vermag, so daß er abspringt. Dieses Verfahren wurde mit einer LeucMgasstichflamme unter Verwendung eines Gebläses ausgeübt.A method for removing scale is known in which by heating the boiler parts affected by scale caused an expansion of these iron parts that the scale is unable to follow, so that it comes off. This method was applied with a LeucM gas stick flame using a blower.
Das vorliegende Verfahren unterscheidetThe present procedure is different
ίο sich davon dadurch, daß nicht die mit Kesselstein behafteten Eisenteile, sondern allein der Kesselstein angewärmt wird. Gelegenheit dazu geben die seit einigen Jahren bekannten Brenner mit besonders heißer Flamme, wieίο by the fact that not those with scale affected iron parts, but only the scale is heated. occasion in addition, there are burners with particularly hot flames that have been known for a number of years, such as
z. B. Acetylensauerstoffbrenner, Wasserstoffsauerstoffbrenner u. dgl., deren Wirkung im allgemeinen auf der Anwendung reinen oder nahezu reinen Sauerstoffes beruht.z. B. acetylene oxygen burner, hydrogen oxygen burner and the like, whose action is generally based on the use of pure or almost pure oxygen.
Diese Brenner mit ihrer auf eine verhältnismäßig eng umgrenzte Stelle gerichteten, große Wärmemengen abgebenden Flamme ermöglichen es, den Kesselstein bis zur Weißglut zu erhitzen, ohne daß das darunter liegende Eisenmaterial erheblich angewärmt wird. Es erfolgt dadurch trotz des geringen Wärmeausdehnungskoeffizienten des Kesselsteins eine Ausdehnung desselben, die die gleichzeitige Ausdenung des Blechmaterials so weit übersteigt, daß der Kesselstein abspringt. Dabei arbeitet das Verfahren erheblieh schneller als das früher verwendete Verfahren mit einer niedriger temperierten Flamme.These burners are aimed at a relatively narrowly delimited place, Large amounts of heat emitting flame make it possible to burn the scale up to incandescence to be heated without the underlying iron material being significantly heated. It is done in spite of the small Coefficient of thermal expansion of the scale is an expansion of the same, which is the simultaneous evaporation of the sheet material so far exceeds that the scale pops off. The process works considerably faster than the one previously used Process with a lower temperature flame.
