Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Betrieb einer Gasturbine gemäß dem Oberbegriff des Anspruchs 1 und eine entsprechende Vorrichtung gemäß dem Oberbegriff des Anspruchs 7.The present invention relates to a method for operating a gas turbine according to the preamble of claim 1 and a corresponding device according to the preamble of claim 7.
Aus der AU-B-496757 bekannt ist ein Verfahren zum Betrieb einer mit vanadiumhaltigem Brennstoff befeuerten Gasturbine, die mindestens einen Brenner in einer Brennkammer sowie Mittel zur Zuführung einer in Wasser gelösten Magnesiumverbindung als Zusatzstoff in die Brennkammer aufweist, wobei der Brenner mit dem Brennstoff beaufschlagt wird.From AU-B-496757 a method for operating a gas turbine fired with vanadium-containing fuel is known, which has at least one burner in a combustion chamber and means for feeding a magnesium compound dissolved in water as an additive into the combustion chamber, the burner acting on the fuel becomes.
Aus der EP-A-0 193 838 ist beispielsweise ein sogenannter Hybridbrenner bekannt, welcher auch Möglichkeiten zur Einspritzung von Wasser oder Dampf in die Verbrennungszone vorsieht. Wegen Einzelheiten der Brennerkonstruktion wird ausdrücklich auf diese Schrift Bezug genommen. Weitere Varianten von Brennern mit zusätzlicher Einspritzung von Inertstoffen sind auch aus der DE-A 36 06 625 bekannt. Wasser und/oder Dampf werden z. B. in die Verbrennungszone einer Brennkammer eingedüst, um dort die Temperatur zu senken und so die Erzeugung von umweltschädigendem NOx zu verringern.From EP-A-0 193 838, for example, a so-called hybrid burner is known, which also provides options for injecting water or steam into the combustion zone. Reference is expressly made to this document for details of the burner construction. Further variants of burners with additional injection of inert substances are also known from DE-A 36 06 625. Water and / or steam are e.g. B. injected into the combustion zone of a combustion chamber to lower the temperature there and thus reduce the generation of environmentally harmful NO x .
Aus dem Stand der Technik ist es ferner bekannt, dem Brennstoff bei der Feuerung von Gasturbinen Additive beizumischen, beispielsweise, um die Bauteile der Gasturbine vor Schäden zu schützen. Insbesondere gibt es Probleme durch vanadiumhaltige Brennstoffe, beispielsweise bestimmte Schweröle. Das Vanadium bildet an den heißgasführenden Bauteilen, insbesondere den Schaufeln einer Gasturbine, niedrigschmelzende Vanadiumverbindungen, die sehr aggressiv sind und schützende Oxidschichten schnell auflösen. Dies führt zu einer stark beschleunigten Hochtemperaturkorrosion. Zur Vermeidung dieser Korrosionsform ist es bekannt, dem Brennstoff Metallverbindungen beizumischen, die während der Verbrennung mit dem Vanadium reagieren und Vanadate bilden, die sich durch so hohe Schmelzpunkte auszeichnen, daß sie bei den üblichen Schaufeltemperaturen in fester Form vorliegen. Unter zahlreichen Metallverbindungen haben sich insbesondere die des Magnesiums bewährt, da sich bei hinreichendem Magnesiumüberschuß Magnesium-Orthovanadat (Mg₃V₂O₈) bildet, das erst bei 1159°C schmilzt. Die entstehenden magnesiumhaltigen Beläge sind andererseits gut von den Schaufeln wieder zu entfernen. Bisher wird das Magnesium dem Brennstoff entweder in Form von öllöslichen Verbindungen, kolloidalen Suspensionen oder in Form von wasserlöslichen Salzen, die emulgiert werden müssen, beigemischt.It is also known from the prior art to add additives to the fuel when firing gas turbines, for example in order to protect the components of the gas turbine from damage. In particular, there are problems with fuels containing vanadium, for example certain heavy oils. The vanadium forms low-melting vanadium compounds on the hot gas-carrying components, in particular the blades of a gas turbine, which are very aggressive and quickly dissolve protective oxide layers. This leads to strongly accelerated high-temperature corrosion. To avoid this form of corrosion, it is known to add metal compounds to the fuel which react with the vanadium during combustion and form vanadates which are characterized by such high melting points that they are in solid form at the usual blade temperatures. Among numerous metal compounds, those of magnesium have proven particularly effective, since magnesium orthovanadate (Mg₃V₂O₈) forms, which only melts at 1159 ° C. The resulting magnesium-containing deposits, on the other hand, are easy to remove from the blades. So far, the magnesium has been added to the fuel either in the form of oil-soluble compounds, colloidal suspensions or in the form of water-soluble salts that have to be emulsified.
Die Herstellung öllöslicher Additive ist sehr aufwendig und hat hohe Kosten zur Folge, die beispielsweise bei hohen Vanadiumgehalten die Verwendung eines Brennstoffes unwirtschaftlich machen können. Die Beimischung von preiswerteren, nicht öllöslichen Magnesium-Verbindungen als Suspension oder Emulsion bereitet schwerwiegende Stabilitätsprobleme und erfordert einen erheblichen apparativen Aufwand. Durch Magnesium-Oxid-Suspensionen kann es zum Verschleiß von Brennerdüsen kommen. Aus der AU-B 496 757, von der die vorliegende Erfindung ausgeht, ist die Verwendung von in Wasser gelöstem Magnesiumsulfat, welches mit dem Brennstoff emulgiert wird, bekannt. Die Dosierung und Mischung mit dem Brennstoff ist jedoch relativ aufwendig und nur schwer konstant zu halten. In fast allen Anwendungsfällen mußte daher bisher auf die teuren öllöslichen Additive zurückgegriffen werden.The production of oil-soluble additives is very complex and entails high costs, which can make the use of a fuel uneconomical, for example at high vanadium contents. The addition of less expensive, non-oil-soluble magnesium compounds as a suspension or emulsion causes serious stability problems and requires considerable equipment. Magnesium oxide suspensions can cause burner nozzles to wear out. From AU-B 496 757, from which the present invention is based, the use of magnesium sulfate dissolved in water, which is emulsified with the fuel, is known. However, metering and mixing with the fuel is relatively complex and difficult to keep constant. In almost all applications, the expensive oil-soluble additives have had to be used.
Vor diesem Hintergrund ist es Aufgabe der vorliegenden Erfindung, ein Verfahren und eine zugehörige Vorrichtung zu schaffen, welche eine zuverlässige und preisgünstige Beimischung von Magnesium in den Verbrennungsprozeß unter Vermeidung der genannten Probleme ermöglichen. Insbesondere soll die Beimischung von im Wasser gelöstem Magnesiumsulfat in den Verbrennungsprozeß vanadiumhaltiger Brennstoffe erleichtert und verbilligt werden.Against this background, it is an object of the present invention to provide a method and an associated device which allow reliable and inexpensive admixture of magnesium in the combustion process while avoiding the problems mentioned. In particular, the admixture of magnesium sulfate dissolved in the water in the combustion process of fuels containing vanadium should be made easier and cheaper.
Zur Lösung dieser Aufgabe wird ein Verfahren gemäß dem Kennzeichen des Anspruchs 1 bzw. eine Vorrichtung gemäß Anspruch 6 angegeben. Vorteilhafte Ausgestaltungen sind in den jeweils abhängigen Ansprüchen angegeben.To achieve this object, a method according to the characterizing part of claim 1 and a device according to claim 6 are specified. Advantageous refinements are specified in the respective dependent claims.
Das gesonderte Eindüsen einer in Wasser gelösten Magnesiumverbindung zusammen mit dem Wasser in die Brennkammer ist verfahrenstechnisch wesentlich leichter zu beherrschen als das emulgieren einer in Wasser gelösten Magnesiumverbindung mit dem Brennstoff. Dadurch kann eine genaue Dosierung des einzubringenden Magnesiumanteils im Verhältnis zum Vanadiumanteil im Brennstoff problemlos bewerkstelligt werden. Die notwendigen Zusatzeinrichtungen am Brenner sind nicht besonders aufwendig und haben sich im Zusammenhang mit der Reduzierung von NOx im Abgas schon bewährt. Durch direktes Einsprühen der in Wasser gelösten Magnesiumverbindung in die Flamme wird praktisch der gleiche Effekt erzielt wie bei einer Eindüsung zusammen mit dem Brennstoff. Als preisgünstige und leicht in Wasser lösbare Magnesiumverbindung kommt vorzugsweise Magnesiumsulfat in Betracht. Pro Gewichtsanteil Vanadium im Brennstoff sollten etwa drei Gewichtsanteile Magnesium zugeführt werden. Dabei läßt sich die Konzentration der wasserlöslichen Magnesiumverbindung im Wasser so einstellen, daß pro Volumenanteil Brennstoff etwa ein Zehntel Volumenanteil Wasser mit gelöster Magnesiumverbindung eingedüst werden muß. Dies stellt technisch kein Problem dar, weil bereits die Eindüsung von wesentlich größeren Anteilen Wasser in anderem Zusammenhang gelöst ist.The separate injection of a magnesium compound dissolved in water In terms of process engineering, it is much easier to control together with the water in the combustion chamber than the emulsification of a magnesium compound dissolved in water with the fuel. As a result, an exact dosage of the magnesium content to be introduced in relation to the vanadium content in the fuel can be achieved without any problems. The necessary additional devices on the burner are not particularly complex and have already proven themselves in connection with the reduction of NO x in the exhaust gas. By spraying the magnesium compound dissolved in water directly into the flame, practically the same effect is achieved as with an injection together with the fuel. Magnesium sulfate is preferably an inexpensive magnesium compound which is easily soluble in water. About three parts by weight of magnesium should be added per part by weight of vanadium in the fuel. The concentration of the water-soluble magnesium compound in the water can be adjusted so that about one tenth of the volume of water with dissolved magnesium compound must be injected per volume of fuel. From a technical point of view, this is not a problem because the injection of much larger portions of water is already solved in another context.
Zur Erläuterung des ganzen Vorganges seien noch folgende Daten gegeben:The following data are given to explain the whole process:
Bei 20° C lösen sich 25,8 %, bei 0° C 20,9 % MgSO₄ in Wasser. In der Brennerflamme läuft dann folgende Reaktion ab:
Die Menge des durch das Sulfat zusätzlich eingeführten Schwefels fällt gegenüber derjenigen Schwefelmenge, die gewöhnlich im Brennstoff enthalten ist, nicht ins Gewicht. Auch ansonsten ergeben sich gegenüber der Beimischung einer öllöslichen Magnesium-Verbindung keine Nachteile für den Verbrennungsprozeß und die entstehenden Emissionen.At 20 ° C 25.8%, at 0 ° C 20.9% MgSO₄ dissolve in water. The following reaction then takes place in the burner flame:
The amount of additional sulfur introduced by the sulfate is insignificant compared to the amount of sulfur usually contained in the fuel. Otherwise there are no disadvantages for the combustion process and the resulting emissions compared to the addition of an oil-soluble magnesium compound.
Die benötigten Mengen seien anhand des folgenden Beispiels erläutert:The required quantities are explained using the following example:
Bei einem angenommenen, relativ hohen Vanadiumgehalt von 300 ppm im Brennstoff und einem Dosierverhältnis Magnesium zu Vanadium von 3 : 1 benötigt eine Gasturbine mit einem Brennstoffverbrauch von 10 kg/s etwa 160 kg MgSO₄/h. Wird eine 20%ige Lösung von MgSO₄ in Wasser eingesetzt, was genügend weit von der Löslichkeitsgrenze entfernt ist, so beträgt die benötigte Lösungsmenge 800 kg bzw. 670 l Lösung/h.With an assumed, relatively high vanadium content of 300 ppm in the fuel and a metering ratio of magnesium to vanadium of 3: 1, a gas turbine with a fuel consumption of 10 kg / s requires about 160 kg MgSO₄ / h. If a 20% solution of MgSO₄ in water is used, which is sufficiently far from the solubility limit, the amount of solution required is 800 kg or 670 l solution / h.
Vorrichtungen zur Durchführung des Verfahrens sind in den Ansprüchen 6, 7 und 8 angegeben. Demgemäß benötigen die an sich bekannten Brenner zur Durchführung des erfindungsgemäßen Verfahrens Zusatzvorrichtungen, nämlich mindestens einen zusätzlichen Vorratsbehälter für eine in Wasser gelöste Magnesiumverbindung und eine Dosiereinrichtung, die die Einspeisung in die Brennkammer über Wasserdüsen ermöglicht.Devices for carrying out the method are specified in claims 6, 7 and 8. Accordingly, the burners known per se require additional devices for carrying out the method according to the invention, namely at least one additional storage container for a magnesium compound dissolved in water and a metering device which enables feeding into the combustion chamber via water nozzles.
