Description
Verfahren zum Beschleunigen der Verbrennung. Die Erfindung bezieht sich auf ein Ver fahren zum Beschleunigen der Verbrennung eines Brennstoffes. Sie ist gekennzeichnet durch die Verwendung von Magnesium oder einer Magnesiumverbindung als Zugabe zu den 'an der Verbrennung teilnehmendedStof- fen, wobei die zugegebene Gewichtsmenge Magnesium mindestens 0,05% der Gewichts menge des Brennstoffes beträgt.
Man hat vorgeschlagen, speziell zur Ver minderung von Zerstörungen an hitzebestän digen Metallteilen bei Temperaturen von über<B>630'C,</B> insbesondere Von' Erhitzerrohren, durch Verbrennungsprodukte, welche durch Verbrennen von Vanadium enthaltenden Brennstoffen erzeugt worden sind, dafür zu sorgen, da.ss bei der Verbrennung Magnesium vorhanden ist, sortdass'das Vanadium in eine Vanadiumverbindung, die dessen Angriffe auf die hitzebeständigen Metallteile bei Tem peraturen von über 630 C vermindert, über geführt wird.
Diesem Vorschlag gegenüber geht der Vorschlag gemäss der Erfindung von einer ganz andern Erkenntnis aus Unabhängig davon, ob Zerstörung von Metallteilen stattfindet und ob diese Metall teile sogena.nnte hitzebeständige sind, unab hängig ferner von der Temperatur und unab hängig davon, ob der zur Verbrennung ge langende Brennstoff Vanadium enthält, ist es das Ziel der Erfindung,
den Strömungs widerstand und die Abmessungen der zur Verbrennung des Brennstoffes dienenden Brennkammer zu verkleinern und dies durch ein Beschleunigen der Verbrennung zu er zielen.
Bisher erwies es sich als notwendig, z. B. in einer Gasturbinenanlage, mit Rücksicht auf die relativ geringe Verbrennungsge schwindigkeit, der Brennkammer nicht nur eine relativ grosse Länge zu geben, sondern überdies noch die Geschwindigkeit eines Teils der diese Brennkammer durchströmenden Luft künstlich für die Dauer der in diesem Teil der Luft stattfindenden Verbrennung abzubremsen, was eine Vergrösserung des Strömungswiderstandes und dazu auch noch des Durchmessers der Brennkammer zur nachteiligen Folge hatte.
Bei Anwendung des Verfahrens nach der Erfindung werden diese Nachteile beseitigt bzw. vermindert. Es entsteht ferner der Vor teil, dass der zu verwendende Brennstoff nicht mehr mit Rücksicht auf hohe Verbren nungsgeschwindigkeit ausgewählt zu werden braucht und auch z. B. für Strahltriebwerke und andere Flugzeuggasturbinen ein billiger Brennstoff verwendet werden darf.
Das Magnesium kann in metallischer Form, z. B. als Metallpulver, es kann auch in Form einer seiner Verbindungen, z. B. in Form von Magnesiumoxyd und von Magne- siumkarbonat, verwendet werden.
Man kann einen Magnesium enthaltenden Stoff oder auch reines Magnesium dem Brenn stoff schon vor dessen Verbrennung zugeben oder auch den Stoff erst während des Ver brennungsvorganges zuführen.
Man kann Magnesium oder eine Magne- siumverbindung schon in Verbrennungsluft oder erst in den Verbrennungsgasen zerstäu ben.
Man kann eine Magnesium enthaltende Flüssigkeit, geschmolzenes Magnesium oder eine gasförmige Magnesiumverbindung, z. B. Magnesiumalkyle, verwenden.
Man kann öllösliche Magnesiumverbin- dungen, z. B. Magnesiumoleate, Magnesium- naphtenate, Magnesiumacetate, verwenden.
Method of accelerating combustion. The invention relates to a process for accelerating the combustion of a fuel. It is characterized by the use of magnesium or a magnesium compound as an addition to the substances participating in the combustion, the added weight of magnesium being at least 0.05% of the weight of the fuel.
It has been proposed, specifically to reduce the destruction of heat-resistant metal parts at temperatures of over 630 ° C, in particular from heater tubes, by combustion products which have been produced by burning vanadium-containing fuels ensure that magnesium is present during combustion, so that the vanadium is converted into a vanadium compound which reduces its attack on the heat-resistant metal parts at temperatures above 630 C.
In relation to this proposal, the proposal according to the invention is based on a completely different insight. Regardless of whether metal parts are destroyed and whether these metal parts are so-called heat-resistant, furthermore independent of the temperature and independent of whether the ge for combustion long-term fuel contains vanadium, the aim of the invention is
to reduce the flow resistance and the dimensions of the combustion chamber used for the combustion of the fuel and to achieve this by accelerating the combustion.
So far it has been found necessary, e.g. B. in a gas turbine system, with regard to the relatively low speed combustion, not only to give the combustion chamber a relatively large length, but also artificially the speed of part of the air flowing through this combustion chamber for the duration of the combustion taking place in this part of the air to slow down, which resulted in an increase in the flow resistance and also in the diameter of the combustion chamber.
When using the method according to the invention, these disadvantages are eliminated or reduced. There is also the part before that the fuel to be used no longer needs to be selected with regard to high combustion speed and also z. B. for jet engines and other aircraft gas turbines a cheap fuel may be used.
The magnesium can be in metallic form, e.g. B. as metal powder, it can also be in the form of one of its compounds, e.g. B. in the form of magnesium oxide and magnesium carbonate can be used.
You can add a magnesium-containing substance or pure magnesium to the fuel before it is burned, or you can only add the substance during the combustion process.
Magnesium or a magnesium compound can already be atomized in the combustion air or only in the combustion gases.
A liquid containing magnesium, molten magnesium or a gaseous magnesium compound, e.g. B. use magnesium alkyls.
You can use oil-soluble magnesium compounds such. B. Magnesium oleates, magnesium naphtenates, magnesium acetates, use.
