Einrichtung zur Verhütung von Korrosionen in Niederdruckdampfheizungen.
Bei Niederdruekdampfheizungen machen sich häufig Korrosionen an den Dampfkesseln bemerkbar.
Die Ursache davon ist, dass die Kondensatleitungen durch das Standrohr mit der freien Luft in Verbindung stehen und sich die ganzen Rohrleitungen sowie die Kessel beim Abstellen der Anlage mit Luft füllen.
Dadurch hat das Wasser Gelegenheit, Sauerstoff aufzunehmen, der dann während des Stillstandes der Kessel korrodierend auf dessen Wandungen einwirkt.
Nach der Erfindung soll dieser Übelstand dadurch beseitigt werden, dass das ganze System von der Luft abgeschlossen und an einen Behälter mit veränderlichem Raum angeschlossen wird, der mit einem indifferenten Gas gefüllt ist.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch veranschaulich. a ist der Dampfkessel, b die zu den Heizkörpern c führende Dampfleitung, d die Rückleitung für das Heizdampfkondensat. Diese Leitung ist über das Ventil e mit einer Gasglocke/verbunden, die z. B. mit Stickstoff gefüllt und durch ein Gewicht g so ausgeglichen ist, dass in ihr ein geringer Überdruck herrscht. h ist ein Luftauslass ins Freie, i ein Sieherheitsstandrohr.
Die Wirkungsweise dieser Einrichtung ist folgende : Zu Beginn der jährlichen Heizperiode wird angeheizt, wobei die Kondensatabscheider der Heizkörper derart umgestellt sind, dass der Dampf frei durchströmt und der entweichende Dampf die Luft aus dem ganzen System durch das Ventil austreibt, wobei das Ventil e geschlossen ist. Sobald das ganze System luftleer ist, wird das Ventil h geschlossen, Ventil e geöffnet und sämtliche Kondensatabscheider der Heizkörper werden angestellt. Der in der Glocke t befindliche Stickstoff fül1t nunmehr alle Rohrleistungen, die bei den jetzt üblichen Ausführungen mit Luft in Berührung kommen. Beim Abstellen des Kessels kondensiert sich der darin befindliehe Dampf und der Dampfraum füllt sich ebenfalls mit Stickstoff.
Falls durch Undichtheiten Stickstoff verloren gehen sollte, sinkt die Glocke f tiefer, bis sie schliesslich auf einen Kontakt aufsitzt, der ein Alarmsignal betätigt.

Device for preventing corrosion in low pressure steam heating systems.
In the case of low-pressure steam heating systems, corrosion is often noticeable on the steam boiler.
The reason for this is that the condensate lines are in contact with the open air through the standpipe and all the pipelines and the boiler fill with air when the system is switched off.
This gives the water the opportunity to absorb oxygen, which then has a corrosive effect on the walls of the boiler while the boiler is at a standstill.
According to the invention, this inconvenience is to be eliminated in that the whole system is closed off from the air and connected to a container with variable space, which is filled with an inert gas.
In the drawing, an embodiment of the subject matter of the invention is illustrated schematically. a is the steam boiler, b the steam line leading to the radiators c, d the return line for the heating steam condensate. This line is connected via the valve e to a gas bell / which z. B. is filled with nitrogen and balanced by a weight g so that there is a slight overpressure in it. h is an air outlet to the outside, i is a safety standpipe.
The mode of operation of this device is as follows: At the beginning of the annual heating season, the heating is started, with the condensate separators of the radiators being adjusted in such a way that the steam flows freely through and the escaping steam expels the air from the entire system through the valve, with valve e closed . As soon as the whole system is evacuated, valve h is closed, valve e is opened and all condensate traps on the radiators are turned on. The nitrogen in the bell now fills all pipe services that come into contact with air in the current designs. When the boiler is switched off, the steam in it condenses and the steam space also fills with nitrogen.
If nitrogen should be lost due to leaks, the bell f sinks lower until it finally rests on a contact that triggers an alarm signal.
