Description
Dampferzeugungsanlage mit einer Gasturbinenanlage Die Erfindung bezieht sich auf eine Dampferzeu- gungsanlage mit einer Gasturbinenanlage, bei der die Abgasleitung der Gasturbine mit der Brennkammer der Dampferzeugungsanlage verbunden ist. Die Ver wendung von Gasturbinenanlagen in Dampferzeu- gungsanlagen ist an sich vorteilhaft, da dadurch der thermische Wirkungsgrad verbessert werden kann.
Schwierigkeiten ergeben sich aber, wenn die Dampf erzeugungsanlage Belastungsschwankungen unterwor fen ist, weil dabei der Wirkungsgrad der Gasturbinen anlage sich rasch verschlechtert.
Die Erfindung ist dadurch gekennzeichnet, dass die Gasturbinenanlage für die Lieferung einer maxi- malen Gasmenge ausgelegt ist, die etwa 70 % der-von der Dampferzeugungsanlage bei Vollast benötigten Brennluftmenge entspricht, und dass ein regelbarer Ventilator vorgesehen ist,
der den Rest der von der Dampferzeugungsanlage benötigten Brennluftmenge liefert.
Ein Ausführungsbeispiel der Erfindung und deren Vorteile sind im folgenden anhand der Zeichnung be schrieben. Die Zeichnung zeigt eine schematische Darstellung einer Dampferzeugungsanlage mit einer Gasturbinenanlage. Die Gasturbinenanlage besteht aus einem von der Gasturbine 1 mit konstanter Dreh zahl angetriebenen Kompressor 2 und einer Brenn kammer 3. Die Brennkammer 3 ist über eine Leitung 4 mit der Austrittseite des Kompressors 2 verbunden. Den Brennstoff (Gas oder Öl) erhält die Brennkam- mer über eine Leitung 6.
Die Ansaugleitung des Kom- pressors ist mit 7 bezeichnet und die Austrittleitung der Turbine 1 mit B. Diese Leitung 8 führt zur Brenn- kammer der Dampferzeugungsanlage 9. Diese ent hält ein Rohrsystem 10, in dem mittels einer nicht dargestellten Speisepumpe zugeführtes Speisewasser in Dampf umgewandelt wird, der über die Leitung 12 einem nichtdargestellten Dampfverbraucher, z. B. einer Dampfturbine, zugeführt wird.
Die Brennkam mer des Dampferzeugers 9 ist mit nicht näher dar gestellten Brennern ausgestattet, die ihren Brennstoff aus der Leitung 13 erhalten. An die Dampferzeuger Brennkammer ist eine Luftzufuhrleitung 14 ange schlossen. Diese Leitung kommt von einem Ventilator 15, der beispielsweise von einem Elektromotor 16 an getrieben ist.
Der Kompressor 2 wird von der Gasturbine 1 im wesentlichen mit konstanter Drehzahl angetrieben, saugt dabei über die Leitung 7 Luft an, komprimiert sie und drückt sie über die Leitung 4 in die Brenn kammer 3. Die hier entstehenden Gase gelangen über die Leitung 5 in die Gasturbine 1, in der sie expan dieren und anschliessend über die Leitung 8 zur Brennkammer des Dampferzeugers 9 strömen.
Diese Gasmenge entspricht etwa 70 % derjenigen Gas- menge, die für die Verbrennung des durch die Leitung 13 bei Vollast des Dampferzeugers zugeführten Brennstoffes benötigt wird.
Wenn der Dampferzeuger mit einer grösseren Last als 70 % fährt, so wird der Rest der erforderlichen Luftmenge mit Hilfe des Ven tilators 15 über die Leitung 14 in die Dampferzeuger- Brennkammer eingeblasen.
Der Ventilator 15 fördert also nur in dem Lastbereich zwischen etwa 70 und 100 %. Er ist regelbar ausgebildet,
indem beispiels- weise die Drehzahl der Antriebswelle verändert wird. Da die 70 % Gasmenge der normalen Vollastgas- menge der Gasturbinenanlage entspricht und die Drehzahl praktisch konstant bleibt, arbeitet die Gas turbinenanlage stets mit gutem Wirkungsgrad,
denn die bei Laständerungen des Dampferzeugers notwen digen Anpassungen in der Brennluftzufuhr werden vom Ventilator 15 übernommen.
Wenn es vorkommt, dass die Dampferzeugungs- anlage häufig mit weniger als etwa 70 % Last oetrie- ben wird, so kann auch dieser Lastbereich von der Gasturbinenanlage gut beherrscht werden, wenn nach einer Ausführungsform der Erfindung in dem Kom pressor 2 eine im Betrieb verstellbare Leitschaufelung vorgesehen ist.
Steam generation system with a gas turbine system The invention relates to a steam generation system with a gas turbine system, in which the exhaust pipe of the gas turbine is connected to the combustion chamber of the steam generation system. The use of gas turbine systems in steam generation systems is advantageous in itself, since this can improve the thermal efficiency.
Difficulties arise, however, when the steam generating plant is subject to fluctuations in load because the efficiency of the gas turbine plant deteriorates rapidly.
The invention is characterized in that the gas turbine system is designed for the delivery of a maximum amount of gas that corresponds to about 70% of the amount of combustion air required by the steam generation system at full load, and that a controllable fan is provided,
which supplies the rest of the amount of combustion air required by the steam generation system.
An embodiment of the invention and its advantages are described below with reference to the drawing be. The drawing shows a schematic representation of a steam generation plant with a gas turbine plant. The gas turbine system consists of a compressor 2 driven at constant speed by the gas turbine 1 and a combustion chamber 3. The combustion chamber 3 is connected to the outlet side of the compressor 2 via a line 4. The combustion chamber receives the fuel (gas or oil) via a line 6.
The suction line of the compressor is denoted by 7 and the outlet line of the turbine 1 by B. This line 8 leads to the combustion chamber of the steam generation system 9. This contains a pipe system 10 in which feed water supplied by a feed pump, not shown, is converted into steam is, the via line 12 to a steam consumer, not shown, z. B. a steam turbine is supplied.
The Brennkam mer of the steam generator 9 is equipped with burners that are not presented in detail and which receive their fuel from line 13. An air supply line 14 is connected to the steam generator combustion chamber. This line comes from a fan 15 which is driven, for example, by an electric motor 16.
The compressor 2 is driven by the gas turbine 1 essentially at constant speed, sucks in air through the line 7, compresses it and pushes it through the line 4 into the combustion chamber 3. The gases produced here pass through the line 5 into the Gas turbine 1, in which they expand and then flow via line 8 to the combustion chamber of the steam generator 9.
This amount of gas corresponds to about 70% of that amount of gas which is required for the combustion of the fuel supplied through line 13 when the steam generator is at full load.
If the steam generator runs with a load greater than 70%, the rest of the required amount of air is blown with the help of the Ven fan 15 via line 14 into the steam generator combustion chamber.
The fan 15 thus only promotes in the load range between approximately 70 and 100%. He is trained adjustable,
by changing the speed of the drive shaft, for example. Since the 70% gas volume corresponds to the normal full load gas volume of the gas turbine system and the speed remains practically constant, the gas turbine system always works with good efficiency,
because the necessary adjustments in the combustion air supply when the steam generator changes load are taken over by the fan 15.
If it happens that the steam generation plant is frequently operated with less than about 70% load, then this load range can also be well controlled by the gas turbine plant if, according to one embodiment of the invention, a guide vanes adjustable during operation in the compressor 2 is provided.
