Description
Einrichtung zur Ausnutzung der Abwärme von industriellen Feuerungen in Druckluftturbinen. Die Erfindung bezieht sich auf eine Einrichtung zur Ausnutzung der AbwÄrme von industriellen Feu-erungen und ist eine weitere Ausbildung der Einrichtung nach Patent 38448o. Bei dem Patent 384 48o dient die Abwärme der Feuerung dazu*, die Druckluftturbine zu treiben.Device for utilizing waste heat from industrial furnaces in compressed air turbines. The invention relates to a device for exploitation the waste heat from industrial furnaces and is a further training of the facility according to patent 38448o. In the 384 48o patent, the waste heat from the furnace is used * to drive the air turbine.
Gemäß der Erfindung wird die Abluft der Turbine ungekühlt der Feuerung, deren Ab-*%ärme zur Erhitzung der Druckluft dient, als vorgewärmte Verbrennungsluft zugeführt, wodurch eine Steigerung der Verbrennungstemperatur der Feuerung stattfindet.According to the invention, the exhaust air from the turbine is uncooled from the furnace, whose waste *% is used to heat the compressed air, as preheated combustion air supplied, whereby an increase in the combustion temperature of the furnace takes place.
Ein Ausführungsbeispiel der Erfindung ist auf der Zeichnung schematisch dargestellt. Das Ausführungsbeisipel zeigt eine Feuerung i mit einem Rost 2 über einer Luftzuführung 7. über der Feuerung i, die mit Brennstoff beliebiger Art beschickt wird, befindet sich die Ausnutzungsstelle 3 der Anlage, von der aus beispielsweise ein Kessel oder eine chemische Anlage gespeist wird. Die Rauchgase der Anlage ziehen über der Verbrauchsstelle durch eü-i Röhrensystem 4 in den Schornstein ab. Die Turbine 5 steht mit der Anlage 1-4 durch ein Leitungssystern 6 in Verbindung, durch welches die Luft in Richtung der eingezeichneten Pfeile läuft, indem sie oben in den Wärmeaustauscher der Anlage 1-4 tritt. Aus dem Wärmeaustauscher fließt die Luft nach der Turbine hin und aus der Turbine wiederum durch ein oder zwei Einlässe 7, 8 in die Feuerun'-.An embodiment of the invention is shown schematically in the drawing. The exemplary embodiment shows a furnace i with a grate 2 above an air supply 7. Above the furnace i, which is charged with any type of fuel, there is the utilization point 3 of the system, from which a boiler or a chemical system, for example, is fed. The flue gases from the system are drawn off through the eü-i pipe system 4 into the chimney above the point of consumption. The turbine 5 is connected to the system 1-4 through a line system 6 through which the air runs in the direction of the arrows drawn by entering the heat exchanger of the system 1-4 at the top. The air flows from the heat exchanger to the turbine and out of the turbine again through one or two inlets 7, 8 into the furnace.
Die Wirkungsweise dieser Anlage ist die folgende: Zunächst wird die Feuerung i in üblicher Weise in Betrieb genommen. Die Einlässe 7 und 8 sind geschlossen. Die Rauchgase der Feuerung fließen durch den Wänneaustauscher4 ab. Hierbei wird die um die Röhren des Wärmeaustauschers liegende Luft erwärmt. jetzt wird der normale Lufteinlaß für die Verbrennungsluft der Feuerung ge# schlossen, und es werden die Einlässe 7 ' und 8 geöffnet. Die Feuerung saug gt nun zunächst die notwendige Verbrennungsluft durch diese Offnungen an. Sie setzt damit die Turbine 5 in Betrieb; es wird die Verbrennungsluftdurch den Verdichterg angesaugt und durch die hohlen Turbinenschaufeln io und den Diffusor i i in die Leitung 6 gedrückt, welche sie dem Wärmeaustauscher 4 zuführt. Aus diesem gelangt die Luft wesentlich erwärmt in die Turbine und beaufschlagtderen Schaufeln. Hierbei verliert die Luft den Hauptteil ihrer Wärme. Der Wärmerest gelangt mit der Abluft der Turbine durch die öffnung 7 und 8 in die Feuerung. Die Temperatur derselben erhoht sich dadurch um ein critsprechendes Maß, und es steig gert sich eritsprechend die Temperatur an der Ausnutzungsstelle.The mode of operation of this system is as follows: First, the furnace i is put into operation in the usual way. The inlets 7 and 8 are closed. The flue gases from the furnace flow through the heat exchanger4. The air around the tubes of the heat exchanger is heated here. now the normal air inlet for the combustion air of the furnace is closed and the inlets 7 ' and 8 are opened. The furnace now first draws in the necessary combustion air through these openings. It puts the turbine 5 into operation; the combustion air is sucked in through the compressor and forced through the hollow turbine blades io and the diffuser ii into the line 6 , which feeds it to the heat exchanger 4. From there, the air reaches the turbine, which is significantly warmed, and acts on its blades. Here the air loses most of its heat. The residual heat reaches the furnace with the exhaust air of the turbine through the openings 7 and 8. The temperature of the same increases by a critical amount, and the temperature at the point of use increases accordingly.
