Verfahren zur Reinigung der von den Heizgasen bestrichenen Heizfläche von Dampf- kesseln.
Bei Dampfkesselfeuerungen bildet sich an der Heizfläche insbesondere bei der Verwendung von schwefelhaltiger Braunkohle ein zäher Belag, der den Wärmeübergang beeinträchtigt und deshalb von Zeit zu Zeit entfernt werden muss. Dieser Belag setzt der mechanischen Reinigung einen beträchtlichen Widerstand entgegen, so dass die Instandhaltung der Feuerungen mit viel Mühe und hohen Kosten verbunden ist.
EMI1.1
fläche von Dampfkessel, gemäss welchem der Dampfkessel mit kaltem W : 1sser tBrunnenwasser) bis über die Feuerlinie gefüllt wird, worauf gesättigter Dampf in den Feuerungsraum eingelassen wird.
Man bedient sich hiezu zweckmässig eines Dampf Verteilers, der aus einem über die ganze Breite der Feuerung sich erstreckenden, mit Damphustrittsöffnungen versehenen Rohr besteht, das durch die Feuerungstür
EMI1.2
Dampf gespeist wird. Die den Feuerraum gegen den Schornstein abschliessende Riuchklappe wird dann so weit geöffnet, bis im letzten Zug der Feuerung Dampf bemerkbar ist.
Nach ganz kurzer Zeit bildet sich an den Wänden und Röhren des Kessels ein feuchter Niederschlag, welcher den die Heizfläche bedeckenden Belag vollkommen aufweicht, so dass er nach Unterbrechung der Dampfzufuhr durch Bespritzen mit einem ganz dünnen Wasserstrahl leicht entfernt werden kann und die Kesselwände bzw. die Rohre metallisch rein erscheinen.

Process for cleaning the heating surface of steam boilers that is coated with hot gases.
In the case of steam boiler firing, a tough coating forms on the heating surface, especially when using sulphurous lignite, which impairs the heat transfer and must therefore be removed from time to time. This coating offers considerable resistance to mechanical cleaning, so that the maintenance of the furnaces is very laborious and expensive.
EMI1.1
area of the steam boiler, according to which the steam boiler is filled with cold water up to the firing line, whereupon saturated steam is let into the furnace.
For this purpose, it is advisable to use a steam distributor which consists of a pipe which extends over the entire width of the furnace and is provided with steam outlets, which passes through the furnace door
EMI1.2
Steam is fed. The flap that closes the combustion chamber from the chimney is then opened until steam is noticeable in the last draft of the furnace.
After a very short time, a moist precipitate forms on the walls and pipes of the boiler, which completely softens the coating covering the heating surface, so that it can easily be removed by spraying with a very thin water jet after interrupting the steam supply and the boiler walls or the Pipes appear metallically pure.
