Description
Die Erfindung betrifft einen Wärmeaustauscher einer Gasturbinengeneratoranordnung zur gleichzeitigen Erzeugung elektrischer Leistung sowie von Wärme für die Entsalzung von Meereswasser.The invention relates to a heat exchanger of a gas turbine generator arrangement for the simultaneous generation of electrical power and heat for the desalination of sea water.
Elektrische Leistung soll mit einem Gasturbinenwechselstromgeneratorsatz erzeugt werden, wogegen der Dampf zur Beaufschlagung der Entsalzungsanlage durch Rückgewinnung von Abwärme der aus der Gasturbine austretenden Abgase erfolgen soll.Electrical power is to be generated with a gas turbine alternator, whereas the steam for loading the desalination plant is to be generated by recovering waste heat from the exhaust gases emerging from the gas turbine.
Bei der Anordnung nach der Erfindung kann auch eine Dampfturbine vom Gegendrucktyp oder vom Derivations- bzw. Anzapf- oder Gleichdruck- und Kondensationstyp zur Erzeugung zusätzlicher elektrischer Leistung eingebaut werden. Solch eine Turbine wird dann mit unter hohem Druck stehendem überhitzten Dampf beaufschlagt, der auf Kosten eines Teils der von den aus der Gasturbine austretenden Abgasen rückgewonnenen Wärme erzeugt wird. Soll die Produktion sowohl von elektrischer Leistung wie entsalzten Wassers erhöht werden, so genügt es, die aus der Gasturbine austretenden Rauchgase unter Verwendung eines Brenners aufzuheizen, der vor dem Rauchgaseinlaß in dem Dampferzeuger eingebaut wird.In the arrangement according to the invention, a steam turbine of the counterpressure type or of the derivative or tapping or equal pressure and condensation type can also be installed to generate additional electrical power. Such a turbine is then subjected to high pressure superheated steam at the expense of a part the heat recovered from the exhaust gases exiting the gas turbine is generated. If the production of both electrical power and desalinated water is to be increased, it is sufficient to heat the flue gases emerging from the gas turbine using a burner which is installed in the steam generator in front of the flue gas inlet.
Die Anordnung nach der Erfindung, verglichen mit üblichen Anordnungen, die elektrische Leistung und entsalztes Wasser mittels einer thermoelektrischen Anlage mit Dampfturbinen vom Gegendrucktyp erzeugen, hat den Vorteil, daß bei gleichem Austrag an entsalztem Wasser die Erzeugung elektrischer Leistung um mehr als das Dreifache die der üblichen Installationen überschreitet und daß der spezifische Verbrauch an Primärenergie (Kalorien pro Kilowattstunde) geringer ist.The arrangement according to the invention, compared with conventional arrangements that generate electrical power and desalinated water by means of a thermoelectric system with steam turbines of the counterpressure type, has the advantage that with the same discharge of desalinated water, the generation of electrical power is more than three times that of the usual Installations and that the specific consumption of primary energy (calories per kilowatt hour) is lower.
Der Vorteil der verbesserten Erzeugung elektrischer Leistung bei gleichem Austrag entsalzten Wassers, wird auch dann aufrecht erhalten, wenn man als Vergleich thermoelektrische Energiekraftanlagen heranzieht, bei denen Turbinen vom Derivations- (derivatien) bzw. Anzapf- und Gleichdrucktyp und Kondensationsturbinen Verwendung finden.The advantage of the improved generation of electrical power with the same discharge of desalinated water is also maintained if one uses as a comparison thermoelectric power plants in which turbines of the derivative (derivatives) or tap and constant pressure type and condensation turbines are used.
Vorgeschlagen wird also eine Anlage zur gleichzeitigen Erzeugung elektrischer Leistung und entsalzten Wassers, bei der die aus einer Gasturbine kommenden Rauchgase ihre fühlbare Wärme an eine Entsalzungsanlage abgeben, so daß das zu entsalzende Wasser erwärmt wird. Besondere Vorteile sind in der besseren Ausnutzung der fühlbaren Wärme durch die Maßnahme nach der Erfindung zu sehen.What is proposed is a system for the simultaneous generation of electrical power and desalinated water, in which the flue gases coming from a gas turbine give off their sensible heat to a desalination system so that the water to be desalinated is heated. Particular advantages can be seen in the better utilization of the sensible heat through the measure according to the invention.
Eine beispielsweise Ausführungsform nach der Erfindung soll nun mit Bezug auf die Figuren 1 und 2 näher erläutert werden.An example embodiment according to the invention will now be explained in more detail with reference to FIGS.
Nach Fig. 1 tritt Luft 1, die bei 2 gefiltert wird, in eine Gasturbine ein, die gebildet wird durch einen Kompressor 3, eine Brennkammer 4 (die mit Brennstoff 14 beaufschlagt wird) und eine Turbine 5, wobei letztere einen elektrischen Generator 6 treibt. Die aus der Turbine 5 kommenden Rauchgase 11 werden in ein Gehäuse 7 geführt, das einen Dampferzeuger (Niederdruck) 8 und gegebenenfalls einen Hochdruckdampferzeuger 9 enthält (beide werden durch vorgewärmtes Wasser 10 beaufschlagt). Nachdem sie an die Dampferzeuger die in ihnen enthaltene fühlbare Wärme abgegeben haben, werden diese Gase in den Schornstein 13 über den Fuchs 12 ausgetragen.According to FIG. 1, air 1, which is filtered at 2, enters a gas turbine which is formed by a compressor 3, a combustion chamber 4 (which is supplied with fuel 14) and a turbine 5, the latter driving an electric generator 6 . The flue gases 11 coming from the turbine 5 are fed into a housing 7 which contains a steam generator (low pressure) 8 and possibly a high pressure steam generator 9 (both are acted upon by preheated water 10). After they have given off the sensible heat contained in them to the steam generator, these gases are discharged into the chimney 13 via the fox 12.
Der im Niederdruckdampferzeuger 8 (5 bis 15 Atmosphären) erzeugte Dampf wird über 15 zur Entsalzungsanlage 16 geführt, wo er verwendet wird, um das zu entsalzende Wasser zu erwärmen. Der von einem gegebenenfalls vorhandenen Hochdruckdampferzeuger 9 (30 bis 70 kg/cm hoch2) kommende Wasserdampf beaufschlagt eine Gegendruckturbine 17 (es kann sich auch um eine Derivations- und Kondensationsturbine handeln, wobei in letzterer der abgeleitete oder Anzapfdampf über 18 zur Entsalzungsanlage 16 geführt wird, wobei die Kondensation im Kondensator 19 stattfindet).The steam generated in the low-pressure steam generator 8 (5 to 15 atmospheres) is fed via 15 to the desalination plant 16, where it is used to heat the water to be desalinated. The water vapor coming from a possibly existing high-pressure steam generator 9 (30 to 70 kg / cm high2) acts on a back pressure turbine 17 (it can also be a derivative and condensation turbine, in the latter of which the discharged or bleed steam is conducted via 18 to the desalination plant 16, the condensation taking place in the condenser 19).
Fig. 2 zeigt eine abgeänderte Ausführungsform, die sich von der oben beschriebenen durch die Anordnung eines Hilfsbrenners 20 unterscheidet, der mittels Brennstoff 14 und durch das Gebläse 21 beaufschlagt wird. Dieser Brenner ermöglicht die Erzeugung entsalzten Wassers und gegebenenfalls elektrischer Leistung auch dann, wenn die Gasturbine steht.FIG. 2 shows a modified embodiment which differs from the one described above by the arrangement of an auxiliary burner 20, which by means of fuel 14 and is acted upon by the fan 21. This burner enables the generation of desalinated water and, if necessary, electrical power even when the gas turbine is at a standstill.
Befindet sich die Gasturbine im Betrieb, so ermöglicht sie zusätzlich die Erzeugung elektrischer Leistung und gleichzeitig die Erzeugung entsalzten Wassers durch weitere Erwärmung der aus der Gasturbine austretenden Rauchgase 14.If the gas turbine is in operation, it also enables the generation of electrical power and, at the same time, the generation of desalinated water by further heating the flue gases 14 emerging from the gas turbine.
