Description
DEUTSCHESGERMAN
Die Erfindung bezieht sich auf verbesserte Gemische für Gasturbinen und Verfahren zu ihrem Betrieb bei Verwendung von schwefel- und vanadinhaltigen Heizölen.The invention relates to improved mixtures for gas turbines and methods for their Operation when using heating oils containing sulfur and vanadium.
Schwere Heizöle, wie Rückstandsheizöle, die in Gasturbinenanlagen verwendet werden können, enthalten wesentliche Mengen Asche, welche oft einen merklichen Vanadingehalt besitzt. Bei der Verbrennung eines solchen Heizöls in den Gasturbinenanlagen der Industrie wird das Vanadin in das hoch reaktionsfähige, bei 690° schmelzende Pentoxyd umgewandelt, was zur Bildung von Ablagerungen auf den Turbinenschaufeln und auch zu einer starken Korrosion derselben führen kann. Die zunehmende Ablagerung von Vanadinabscheidungen kann im Betrieb zu einem ernsthaften Sinken des Wirkungsgrades führen.Contain heavy fuel oils, such as residual fuel oils, which can be used in gas turbine systems substantial amounts of ash, which often has a noticeable vanadium content. When burning of such fuel oil in the gas turbine industry, the vanadium is high in the reactive pentoxide, which melts at 690 °, is converted, which leads to the formation of deposits the turbine blades and can also lead to severe corrosion of the same. The increasing Deposition of vanadium deposits can lead to a serious decrease in efficiency during operation to lead.
Man hat das Problem der Vanadin- und Schwefelkorrosion seit langem erkannt und viele Versuche gemacht, es zu lösen, Über den Mechanismus dieser Korrosionseirscheinungen herrschen die verschiedensten Meinungen. Die Schwefelkorrosion und -reaktionsfähigkeit in Gasturbinenanlagen wird im allgemeinen hauptsächlich auf die Bildung von S O3 zurückgeführt. Während einige Fachleute die Ansicht verneinen, daß die Umwandlung von S O2 zu S O3 durch Vanadinoxyde katalysiert werden kann, wird dieselbe von anderen verteidigt.The problem of vanadium and sulfur corrosion has long been recognized and many attempts have been made to solve it. Opinions of the most varied prevail about the mechanism of these corrosion phenomena. Sulfur corrosion and reactivity in gas turbine plants is generally attributed primarily to the formation of SO 3 . While some skilled in the art deny that the conversion of SO 2 to SO 3 can be catalyzed by vanadium oxides, others defend it.
Die britische Patentschrift 705 176 bezieht sich auf die Verbrennung von schwefel- und bzw. oder vanadinhaltigen Heizölen in Gegenwart einer Dispersion einer kleineren Menge einer Erdalkaliverbindung in Form einer wäßrigen Lösung oder Aufschlämmung, wobei der Hauptteil des im Heizöl enthaltenen reaktionsfähigen S O3 und Vanadins in die entsprechenden Sulfate und Vanadate des zugesetzten Erdalkalimetalls umgewandelt wird. Man kann Oxyde oder Verbindungen von Ba, Ca, Zn oder Mg verwenden; in einigen Fällen ist es vorteilhaft, das Metall in Form eines organischen Salzes, wie eines Acetats, einzuführen. Gegenstand jener Erfindung war jedoch, sowohl den Schwefel als auch das Vanadin zu entfernen, so daß der Zusatz von Sulfaten nicht in Betracht gezogen wurde.British patent specification 705 176 relates to the combustion of sulfur and / or vanadium-containing heating oils in the presence of a dispersion of a smaller amount of an alkaline earth compound in the form of an aqueous solution or slurry, with the majority of the reactive SO 3 and vanadium contained in the heating oil in the corresponding sulfates and vanadates of the added alkaline earth metal is converted. Oxides or compounds of Ba, Ca, Zn or Mg can be used; in some cases it is advantageous to introduce the metal in the form of an organic salt such as an acetate. However, the object of that invention was to remove both the sulfur and the vanadium so that the addition of sulfates was not considered.
Nach der deutschen Patentschrift 819 032 soll die Verbrennung vanadinhaltiger öle in Gegenwart von Verbindungen des Calciums, Magnesiums, Bariums, Strontiums, Aluminiums, Siliciutns oder Zirkons ausgeführt werden. Dieser Zusatz dient zur Überführung des Vanadins in eine Vanadinverbindung, die bei Temperaturen oberhalb 630° weniger korrosiv wirkt als Vanadinoxyd, und kann sowohl getrennt vom Brennstoff als auch in Mischung mit demselben erfolgen. Auch die Beimischung von 0,12% Al2O3 zum Verfahren zur Herstellung heißer GaseAccording to German Patent 819 032, the combustion of oils containing vanadium is to be carried out in the presence of compounds of calcium, magnesium, barium, strontium, aluminum, silicon or zirconium. This addition serves to convert the vanadium into a vanadium compound, which is less corrosive than vanadium oxide at temperatures above 630 °, and can be carried out separately from the fuel or mixed with it. Also the addition of 0.12% Al 2 O 3 to the process for the production of hot gases

Brennstoff als Suspension einer anorganischen AIuminiiumverbindung ist bereits zu dem gleichen Zwecke vorgeschlagen worden.Fuel as a suspension of an inorganic aluminum compound has already been proposed for the same purpose.
Viele Heizöle enthalten sowohl Schwefel als auch Vanadin in sehr großen Mengen, und erfordern daher große Mengen von Zusätzen, damit mit Sicherheit der gesamte S- und V-Gehalt praktisch vollständig umgewandelt wird. Wenn aus irgendeinem Grunde, z. B. aus Kostengründen oder wegen eines unerwartet hohen S-Gehaltes des Öls, ein zu geringer Zusatz beigegeben wird, kann auf Kosten der \^anadatbildung vorwiegend Sulfat gebildet werden, was im Falle von Erdalkalimetallen von dem jeweils als Zusatz verwendeten Metall abhängt. Eine solche bevorzugte Umwandlung des Schwefels hängt von der Beständigkeit des jeweiligen gebildeten Sulfats und von a) der Betriebstemperatur der Gasturbine sowie b) dem Reaktionsvermögen des Vanadinoxyds mit dem Erdalkalimetall ab.Many heating oils contain both sulfur and vanadium in very large quantities, and therefore require large amounts of additives, so that the entire S and V content is almost completely converted with certainty will. If for any reason, e.g. B. for cost reasons or because of an unexpected high S-content of the oil, too little addition, can be at the expense of the formation of anadate predominantly sulfate are formed, which in the case of alkaline earth metals of the respective as Addition depends on the metal used. Such a preferred conversion of the sulfur depends on the Resistance of the respective sulfate formed and of a) the operating temperature of the gas turbine and b) the reactivity of the vanadium oxide with the alkaline earth metal.
Die zur Reaktion des Vanadinoxyds erforderliche Temperatur liegt fast immer merklich unterhalb der Betriebstemperatur der Gasturbine. Die Betriebstemperatur von Industriegasturbinen kann man zu etwa 850° ansetzen. Die Reaktionstemperatur von Calciumoxyd mit Vanadinpentoxyd beträgt etwaThe temperature required for the reaction of the vanadium oxide is almost always well below the Operating temperature of the gas turbine. The operating temperature of industrial gas turbines can be too apply about 850 °. The reaction temperature of calcium oxide with vanadium pentoxide is about

weitgehend aus dem System entfernt wird. Patentansprüche:According to the invention, therefore, tin sulphate is used. Sulphate can be seen in the fact that in the case of strong as an additive in the combustion of sulfur-containing heating stoves containing vanadium and heating oil containing vanadium. During operation, because of the instability of the sulphate at the temperature, this sulphate decomposes with the formation of gas turbines and the volatile SO 2 and SO 3 , which from the reaction-relative stability of the vanadate are only rinsed in a small area, while the tin oxide for 65 amounts of the additive required according to the invention reaction with vanadium pentoxide remains and are Hch,
this is converted into a stable vanadate, which
is largely removed from the system. Patent claims:
