Description

Verfahren zur mittelbaren Erzeugung von Dampf. Die bisherigen: Dampferzeuger mittels einer Heizflüssigkeit von :hohem Siedepunkt sind für die jetzt in Gebrauch kommenden hohen Drücke und Temperaturen nicht mehr geeignet, weil die Heizflüssigkeit verdampft und dadurch die Wärmevermittlung verhindert wird.Process for the indirect generation of steam. The previous ones: steam generators by means of a heating fluid of: high boiling point are for now in use coming high pressures and temperatures no longer suitable because the heating fluid evaporates and thus the heat transfer is prevented.

Um die Vorteile eines indirekt beheizten Dampferzeugers auch bei sehr hohen Dampfspannungen zu haben, wird gemäß dieser Er-Tindung die hochsiedende Heizflüssigkeit unter ! .einen bestimmten überdruck gebracht und hierdurch der an sich schon hohe Siedepunkt der Heizflüssigkeit noch weiter heraufgesetzt.To the advantages of an indirectly heated steam generator even with very According to this invention, having high vapor tensions becomes the high-boiling heating fluid under ! .brought a certain overpressure and thereby the already high one Boiling point of the heating fluid increased even further.

In den Abb. i und 2 isst die Grundlage der Erfindung schematisch dargestellt.In Figs. I and 2 the basis of the invention is shown schematically.

Feuerung A dient zum Erzeugen von Hochdruckdampf im Kessel B, der mit der Feuerung nicht in direkter Berührung ist, sondern i gemäß Abb. i und 2 in einem besonderen Behälter C steht.Firing A is used to generate high-pressure steam in boiler B, the is not in direct contact with the furnace, but i according to Fig. i and 2 in a special container C.

Der Behälter C ist durch die Wand D geschlossen und bis a-a mit einer hochsiedenden Heizflüssigkeit gefüllt; über u-a befindet sich Preßluft, Preßgas o. dgl., wodurch der Siede- j punk-t der Heizflüssigkeit um eine von der Größe der Pressung abhängige, bestimmte Zahl von Graden heraufgesetzt wird.The container C is closed by the wall D and to a-a with a high-boiling heating fluid filled; above u-a there is compressed air, compressed gas o. The like., whereby the boiling point of the heating fluid by one of the size of the Pressure dependent, certain number of degrees is increased.

Diese künstliche Erhöhung des Siedepunktes wird so gewählt, daß die Feuerung A noch eben veimäg, die Heizflüssigkeit bis zum Sieden zu bringen.This artificial increase in the boiling point is chosen so that the Furnace A just managed to bring the heating fluid to the boil.

Durch den Kreislauf der Heizflüssigkeit im Behälter C oder in einer geeigneten anderen Vorrichtung, wie Rohrleitungen u. dgl., hat die bis zum Sieden: erwärmte Heizflüssigkeit immer wieder Gelegenheit, die Wärme an den Kessel B abzugeben:, wobei die jeweils entstandenen Dämpfe der Heizflüssigkeit an der Wandfläche D sogleich wieder niedergeschlagen werden.By circulating the heating fluid in container C or in a suitable other device, such as pipelines and the like, has the up to boiling: heated heating fluid has the opportunity to transfer the heat to boiler B :, the respective vapors of the heating fluid produced on the wall surface D immediately to be knocked down again.

In Abb. i ist zur weiteren Abkühlung der Heizflüssigkeit beispielsweise eirn Behälter Dl (als Speisewasservorw .ärmer) und in Abb. 2 ein hiederdruckkessel E angeordnet; im übrigen ist die Abkühlung auf die verschiedenste Art möglich.In Fig. 1, for example, a tank Dl (as feed water preheater) is arranged for further cooling of the heating fluid and in Fig. 2 a low-pressure boiler E is arranged; Otherwise, the cooling is possible in the most varied of ways.

Durch diese indiredce Beheizung des Kessels B wird bei guter thermischer Wirkung durch die im Siedepunkt heraufgesetzte Heizflüssigkeit das Ansetzen von Kesselstein verhütet und die Explosionsgefahr beseitigt.By this indiredce heating of the boiler B is with good thermal Effect due to the heating liquid raised in boiling point the formation of Prevents scale and eliminates the risk of explosion.

Die Feuerung kajm auch durch Gas, Öl, Elektrizität usw. erfolgen.Firing can also be done by gas, oil, electricity, etc.
