Description

Verfahren zur Ausnutzung der beim Abschlammen des Dampfkessels anfallenden Energie- und Wassermengen Bei der heute allgemein üblichen chemischen Speisewasseraufbereitung für Dampfkessel wird in kurzer Zeit die Salzanreicherung im Kessel so hoch, daß ein Teil des Kesselwassers, durchschnittlich a bis ß des eingespeisten Wassers, aus dem Kessel abgeführt werden muß, um ein Schäumen des Kesselinhaltes zu vermeiden.Process for the utilization of the incurred when the steam boiler is blown down Amount of energy and water With the chemical feed water treatment that is generally used today For steam boilers, the salt accumulation in the boiler is so high in a short time that part of the boiler water, on average a to ß of the water fed in, must be discharged from the boiler in order to avoid foaming of the boiler contents.

In vielen Fällen wird dieses Wasser unmittelbar und uriverwertet ins Freie abgelassen, wobei natürlich die in ihm enthaltenen Wärmemengen und sonstigen Energien verlorengehen. In anderen Fällen wird die in dem abgezogenen Wasser vorhandene Wärme in Wärmeaustauschern auf das zuzuführende Kesselspeisewasser übergeführt. Hierbeigeht gewöhnlich noch ein Teil der Wärme verloren, der beim Austritt aus dem W.ärmeaustauscher noch im Wasser enthalten ist. Insbesondere gelingt es hierbei nicht, auch diejenige Energie für den Verdampfungsprozeß des Kesselwassers nutzbar zu machen, die in dem abgebogenen, unter Druck stehenden Wasser selbst liegt. Auch gestaltet sich die Ausnutzung in Wärmeaustaus.chern umständlich und ist vor allem dort nicht anwendbar, wo bereits Speisewasser mit höheren Temperaturen verfügbar ist oder anderweit heißes Kondensat, Abdampf, Anzapfdampf usw. zur Speisewasservorwärmung genügend zur Verfügung steht. Eine nutzbringende Verwendung des- Abschlammwassers kommt in all diesen Fällen nicht in Frage.In many cases, this water is directly recycled and recycled Drained free, with of course the amounts of heat contained in it and other Energies are lost. In other cases it will be that present in the withdrawn water Heat transferred to the boiler feed water to be supplied in heat exchangers. Usually some of the heat that is lost when it exits the The heat exchanger is still in the water. In particular, it succeeds here not, that energy can also be used for the evaporation process of the boiler water to make, which lies in the bent, pressurized water itself. Even The utilization in Wärmeaustaus.chern turns out to be cumbersome and, above all, is Not applicable where feed water with higher temperatures is already available or otherwise hot condensate, exhaust steam, bleed steam etc. for preheating the feed water enough is available. A beneficial use of the blowdown water is out of the question in all of these cases.

Diese Mängel der Energieverluste werden gemäß der Erfindung dadurch behoben, daß das nach dem Abblasen unter vollem Kesseldruck stehende Abschlammwasser als Dampfwassergemisch zur Brennstoffschicht des Kessels geführt wird, indem es zuvor, wenn erforderlich, gefiltert und dann in an sich bekannter Weise fein zerstäubt wird. Auf diese Weise fallen Wärmeaustauscher und alle Wärmeverluste weg, und es gelingt ferner, neben dem Wärmeinhalt auch die Druckenergie des heißen Abschlammwassers nutzbar zu machen, dabei aber gleichzeitig die wesentlichen Vorteile ohne besondere Kosten zu erhalten, die durch die bekannte Zuführung von zerstäubtem Frischwasser oder Dampf erzielt werden, nämlich die Verbesserung der Verbrennung, die Abkühlung der Roststäbe, die Auflockerung der Schlacken und deren leichteres Lösen von den Rosten. Dem letztgenannten Verfahren gegenüber tritt bei dem neuen Verfahren der Fortschritt hervor, daß nicht besonders Frischwasser öder Dampf gebraucht wird, sondern die gleichen Vorteile durch die Verwendung des sonst nur in bezug auf seinen Wärmeinhalt ausgenutzten abfließenden Schlammwassers erzielt werden.These deficiencies in energy losses are thereby made according to the invention remedied that the blowdown water, which was under full boiler pressure after blowing off is fed as a steam-water mixture to the fuel layer of the boiler by filtered beforehand, if necessary, and then finely atomized in a manner known per se will. In this way, heat exchangers and all heat losses are eliminated, and it Furthermore, in addition to the heat content, the pressure energy of the hot blow-down water is also successful to make usable, but at the same time the essential advantages without special To maintain costs by the well-known supply of atomized fresh water or steam can be achieved, namely the improvement of the combustion, the cooling the grate bars, the loosening of the slag and its easier detachment from the Roast. In contrast to the last-mentioned procedure, the Progress shows that not particularly fresh water or steam is needed, but the same advantages by using the otherwise only in relation to his Heat content can be achieved by utilizing draining sludge water.
