Description
Verfahren zum Beschleunigen der Verbrennung. Die Erfindung bezieht. sieh auf ein Ver fahren zum Beschleunigen der Verbrennung eines Brennstoffes. Sie ist gekennzeichnet durch die Verwendung von bei der Verbren nung feuerfeste oxydische Verbindungen ergebenden Substanzen als Zugabe zit den an der Verbrennung teilnehmenden Stoffen, in einer Gewichtsmenge, welche mindestens 0,05% der Gewichtsmenge des Brennstoffes beträgt.
Ion hat. vorgeschlagen, speziell zur Ver minderung von Zerstörungen an hitzebestän digen Metallteilen bei Temperaturen von über 630 C, insbesondere von Erhitzerrohren, durch Verbrennungsprodukte, welche durch Verbrennen von Vanadium enthaltenden Brennstoffen erzeugt worden sind, dafür zu sorgen, dass bei der Verbrennung Zusatz stoffe vorhanden sind, durch welche das Va- iiadinrii in eine Vanadiumverbindung Über- < geführt wird, die dessen Angriffe auf die hitzebeständigen Metallteile bei Temperaturen von über 630 C vermindert.
Diesem Vorschlag gegenüber geht der V orsehlag gemäss der Erfindung von einer ganz andern Erkenntnis aus: Unabhängig davon, ob Zerstörung von Metallteilen stattfindet und ob diese Metall- teile sogenannte hitzebeständige sind, unab hängig ferner von der Temperatur und unab hängig davon, ob der zur Verbrennung gelan- äende Brennstoff Vanadium enthält, gestattet die Erfindung,
den Strömungswiderstand und die Abmessungen der zur Verbrennung des Brennstoffes dienenden Brennkammer gegenüber dem bisher Bekannten zu verklei nern und dies durch ein Beschleunigen dei Verbrennung zu erzielen.
Bisher erwies es sich als notwendig, zum Beispiel in einer Gasturbinenanlage, mit Rüeksieht auf die relativ geringe Verbren nungsgeschwindigkeit, der Brennkammer nicht nur eine relativ grosse Länge zu geben, sondern überdies noch die Geschwindigkeit eines Teils der diese Brennkammer dLirchströ- menden Luft künstlich für die Dauer der in diesem Teil der Luft stattfindenden Verbren nung 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 zum Beispiel für Strahl triebwerke und andere Flugzeuggasturbinen ein billiger Brennstoff verwendet werden darf.
Die feuerfesten oxydischen Verbindungen, welche sich beim Verfahren gemäss der Erfin dung ergeben, führen zu einer wesentlichen Beschleunigung des Verbrennungsvorganges, wobei die an den feuerfesten oxydischen Ver bindungen entstehenden Oberflächen ansehei- nend ähnlich wirken wie es von der Oberflä- echenverbrennung her bekannt, ist.
Es ist daher auch zweckmässig, alle lIass- na.hmen zu ergreifen um eine möglichst feine Verteilung der sich bildenden feuerfesten oxydischen Verbindungen zu erzielen. Dies ist zum Beispiel der Fall, wenn man als oxydbil- dende Substanz ein Metallpulver, z. B. Magne- sium- oder Aluminiumpulver, eine organimelie Metallverbindung, z. B. Magnesiiun-Napli- tenat oder -Oleat, einen Metalldampf, z. B.
Magnesiumdampf oder auch eine dampfför- mige organische Metallverbindung, z. B. dampfförmiges Magnesiumalkyl, dem Brenn Stoff zugibt.
Method of accelerating combustion. The invention relates. see a method for accelerating the combustion of a fuel. It is characterized by the use of refractory oxidic compounds resulting from the combustion as an addition to the substances participating in the combustion, in an amount by weight which is at least 0.05% of the amount by weight of the fuel.
Ion has. Suggested, specifically to reduce the destruction of heat-resistant metal parts at temperatures of over 630 C, especially of heater tubes, by combustion products which have been generated by burning vanadium-containing fuels, to ensure that additives are present during combustion, by means of which the variadinrii is converted into a vanadium compound, which reduces its attacks on the heat-resistant metal parts at temperatures above 630 C.
In contrast 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, regardless of the temperature and regardless of whether they are intended to be burned the fuel that occurs contains vanadium, the invention allows
to reduce the flow resistance and the dimensions of the combustion chamber used for the combustion of the fuel compared to the previously known and to achieve this by accelerating the combustion.
So far it has been shown to be necessary, for example in a gas turbine system, with due regard to the relatively low combustion speed, not only to give the combustion chamber a relatively large length, but also to artificially allow the speed of part of the air flowing through this combustion chamber for the To slow down the duration of the combustion taking place in this part of the air,
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 advantage that the fuel to be used no longer needs to be selected with regard to high combustion speed and a cheaper fuel may also be used, for example, for jet engines and other aircraft gas turbines.
The refractory oxidic compounds which result from the method according to the invention lead to a substantial acceleration of the combustion process, the surfaces arising on the refractory oxidic compounds appearing to have a similar effect as is known from surface combustion.
It is therefore also advisable to take all measures to achieve the finest possible distribution of the refractory oxidic compounds that are formed. This is the case, for example, if the oxide-forming substance is a metal powder, e.g. B. magnesium or aluminum powder, an organimelie metal compound, z. B. Magnesiiun-Napletenat or oleate, a metal vapor, z. B.
Magnesium vapor or a vaporous organic metal compound, e.g. B. vaporous magnesium alkyl, the fuel adds.
