Die Figur zeigt eine schematische Darstellung der Einrichtung zur Energierückgewinnung.The figure shows a schematic representation of the device for energy recovery.
Die Einrichtung weist einen Dampferzeuger 1 auf. Dieser besitzt eingangsseitig einen Eingangsstutzen 2 zum Verbinden mit einer abgaseerzeugenden Einrichtung, beispielsweise einem Kupolofen. Ausgangsseitig ist ein Ausgangsstutzen 3 zum Verbinden mit einem Schornstein 4 vorgesehen. Der Dampferzeuger weist einen an sich bekannten Aufbau nach dem Wärmetauscherprinzip mit Vorwärmer, Verdampfer und Überhitzer auf.The device has a steam generator 1. This has an inlet connection 2 on the input side for connection to an exhaust gas generating device, for example a cupola furnace. An outlet connection 3 is provided on the outlet side for connection to a chimney 4. The steam generator has a known construction based on the heat exchanger principle with preheater, evaporator and superheater.
Ferner weist die Einrichtung eine Wärmekraftmaschine 5 in Form einer Gegendruckdampfturbine auf. Der Dampfausgang des Dampfer¬ zeugers 1 ist über eine Leitung 6 mit dem Eingang der Wärmekraft¬ maschine 5 verbunden. Anstelle der GegendruCakdampfturbine kann auch eine Kondensationsturbine oder ein Dampfmotor verwendet wer- den.Furthermore, the device has a heat engine 5 in the form of a counter-pressure steam turbine. The steam outlet of the steam generator 1 is connected via a line 6 to the inlet of the heat engine 5. Instead of the counter-pressure steam turbine, a condensation turbine or a steam engine can also be used.
Ferner ist eine Arbeitsmaschine S in Form eines Schraubenkompresso vorgesehen. Eine Welle 9 des Schraubenkompressors ist mit der Welle 10 der Wärmekraf maschine kraftschlüssig verbunden. Anstelle des Schraubenkompressors kann auch ein Turbokompressor oder eine Pumpe vorgesehen sein.Furthermore, a work machine S is provided in the form of a screw compressor. A shaft 9 of the screw compressor is non-positively connected to the shaft 10 of the heat engine. Instead of the screw compressor, a turbo compressor or a pump can also be provided.
Ferner ist eine Steuereinrichtung 11 vorgesehen. Diese ist eingangsseitig mit einer Meßeinrichtung 12 verbunden, die an dem Eingangsstutzen 2 angeordnet ist und die dem Dampferzeuger jeweils zugeführte Wärmemenge mißt. Der Ausgang der Steuerein¬ richtung 11 ist zum Steuern mit jeweilseinem Steuereingang des Schraubenkompressors verbunden.A control device 11 is also provided. This is connected on the input side to a measuring device 12 which is arranged on the inlet connection 2 and which measures the amount of heat supplied to the steam generator. The output of the control device 11 is connected to a control input of the screw compressor for control purposes.
Ferner ist ein Wärmetauscher 13 vorgesehen. In dem gezeigten Ausführungsbeispiei handelt es sich um einen Wärmetauscher zum Erwärmen von Luft, die als Warmluft zum Heizen verwendet wird. In gleicher Weise kann aber auch ein Wärmetauscher zum Erzeugen von Warmwasser oder ähnlichem vorgesehen sein. Die Eingangsseite des Wärmetauschers 13 ist über eine Leitung 14 und ein Drossel¬ ventil 7 mit der Abdampfseite der Wärmekraftmaschine 5 verbunden. Der Wärmetauscher 13 weist einen Kondensator auf. Der Ausgang des Kondensators ist über eine Leitung 15 mit einer S eisewasser- Versorgung 16 verbunden, die ihrerseits wiederum über eine Lei¬ tung 17 mit der Wassereinlaßseite des Dampferzeugers 1 verbunden ist, so daß ein Kreislauf der Dampf-Wasser-Dampf Leitung gegeben ist.A heat exchanger 13 is also provided. In the exemplary embodiment shown, it is a heat exchanger for heating air, which is used as warm air for heating. In the same way, however, a heat exchanger for generating hot water or the like can also be provided. The input side of the heat exchanger 13 is connected to the exhaust steam side of the heat engine 5 via a line 14 and a throttle valve 7. The heat exchanger 13 has a condenser. The output of the condenser is connected via a line 15 to an ice water supply 16, which in turn is connected via a line 17 to the water inlet side of the steam generator 1, so that a circuit of the steam-water-steam line is provided.
Zusätzlich zu der oben beschriebenen Verbindung zwischen Steuer¬ einrichtung 11 und Schraubenkompressor ist die Steuereinrichtung über einen weiteren Ausgang mit dem Drosselventil 7 zur Ansteuerun desselben verbunden.In addition to the connection between the control device 11 and the screw compressor described above, the control device is connected to the throttle valve 7 for controlling the same via a further output.
Im Betrieb wird über den Eingangsstutzen 2 Rauchgas oder ein sonstiges Wärmeenergie enthaltendes Gas zugeführt und über den Dampferzeuger überhitzter Dampf erzeugt, der über die Leitung 6 der als Gegendruckdampfturbineausgebildeten Wärmekraftmaschine 5 zugeführt wird. Die Dampfturbine treibt über ihre Welle 10 und die mit ihr kraftschlüssig verbundene gemeinsame Welle 9 des Schraubenkompressors diesen an. Das durch den Kompressor komprimierte Fluid wird in bekannter Weise über Ausgänge einem Verbraucher zugeführt.In operation, flue gas or another gas containing thermal energy is supplied via the inlet connection 2 and superheated steam is generated via the steam generator, which is supplied via line 6 to the heat engine 5 designed as a counter-pressure steam turbine. The steam turbine drives via its shaft 10 and the common shaft 9 of the non-positively connected to it Screw compressor on this. The fluid compressed by the compressor is supplied to a consumer in a known manner via outputs.
Der Schraubenkompressor hat zum Steuern in bekannter Weise Schieber- oder überStromregeleinrichtungen, mit denen sie ge¬ nügend ab- bzw. hochgeregelt werden können. Die Steuerein¬ richtung 11 ist in Abhängigkeit von der Auslegung der Dampf¬ turbine so ausgebildet, daß sie die Leistungsaufnahme des Schraubenkompressors in Abhängigkeit von der mit der Me߬ einrichtung 12 gemessenen Leistung so einstellt, daß die Leistungsaufnahme des Kompressors nicht größer und vorzugs¬ weise einige Prozent kleiner ist als die Ausgangsleistung der Dampfturbine, wenn diese in ihrem optimalen Betriebsbereich betrieben wird. Diese Ausgangsleistung der Dampfturbine ent¬ spricht der der Dampfturbine zugeführten Leistung mal dem Wir¬ kungsgrad der Dampfturbine im optimalen Ξetriebsbereich. Durch die Steuerung ist es möglich, zeitgleich mit dem Zusammenbruch der Dampfproduktion den Leistungsbedarf der Arbeitsmaschine 8 zu reduzieren und die Dampf urbine auch im Teillastbereich zu halten.For control, the screw compressor has slider or flow control devices in a known manner, with which they can be regulated down or up sufficiently. Depending on the design of the steam turbine, the control device 11 is designed in such a way that it adjusts the power consumption of the screw compressor in dependence on the power measured with the measuring device 12 such that the power consumption of the compressor is not greater and preferably is a few percent less than the output power of the steam turbine when it is operated in its optimal operating range. This output power of the steam turbine corresponds to the power supplied to the steam turbine times the efficiency of the steam turbine in the optimal operating range. The control makes it possible to reduce the power requirement of the work machine 8 at the same time as the steam production collapses and to keep the steam turbine also in the partial load range.
Die Einrichtung weist ferner eine Mengenmeßeinrichtung 18 zum Bestimmen der dem Überhitzer des Dampferzeugers zugeführten Dampf enge und damit auch der der Dampfturbine zugeführten Dampf enge auf. Das Ausgangssignal dieser Mengenmeßeinrichtung 18 wird über eine Leitung einem Eingang der Steuereinrichtung 11 zugeführt. In Abhängigkeit von dem so zugeführten Meßsignal steuert die Steuereinrichtung 11 das Drosselventil 7 derart, daß der Dampfdruck konstant bleibt und die Menge so verändert wird, daß die Drehzahl der Dampfturbine nahezu konstant bleibt.The device also has a quantity measuring device 18 for determining the narrow steam supplied to the superheater of the steam generator and thus also the narrow steam supplied to the steam turbine. The output signal of this quantity measuring device 18 is fed to an input of the control device 11 via a line. Depending on the measurement signal supplied in this way, the control device 11 controls the throttle valve 7 in such a way that the steam pressure remains constant and the quantity is changed such that the speed of the steam turbine remains almost constant.
Der Abdampf vom Ausgang der Dampfturbine 5 wird über die Leitung 14 dem Wärmetauscher 13 zugeführt. In dem Ausführungsbeispiel wird an einem Luftkondensator Luft erwärmt und über eine ent¬ sprechende Ausgangsleitung beispielsweise einer Hallenheizung zugeführt. Der .Abdampf schlägt sich an dem Kondensator nieder und wird über die Leitung 15 zur Speisewasserversorgung rückgeführt. In der Speisewasserversorgung 16 kann in geeigneter Weise eine Aufbereitung erfolgen. Von der Speisewasserversorgung wird schließlich aufbereitetes Wasser dem Dampferzeuger zugeführt.The waste steam from the outlet of the steam turbine 5 is fed to the heat exchanger 13 via the line 14. In the embodiment air is heated at an air condenser and supplied to a hall heating via a corresponding output line, for example. The .Abdampf precipitates on the condenser and is returned via line 15 to the feed water supply. In the feed water supply 16, treatment can take place in a suitable manner. Finally, treated water is fed to the steam generator from the feed water supply.
Mit der oben beschriebenen Einrichtung wird beispielsweise ein dem Eingang des Dampferzeugers zugeführtes Gichtgas von 600 °C auf 180 °C abgekühlt und bringt eine Wärmemenge von etwa 8,0 MWh bei 36 t/h Schmelzleistung. Hiervon werden ca. 15 % durch die Schraubenkompressoren in mechanische Arbeit umgewandelt. Durch die Ausnutzung der Abwärme der Dampfturbine erfolgt eine weitere Ausnutzung der zugeführten Energie. Dadurch steigt der Gesamtnutzen gegenüber dem Nutzen bei bisherigen Lösungen erheblich an. Der in einem -solchen Betrieb permanent hohe Druckluftbetrieb erlaubt die totale Abnahme der erzeugten Druckluft und die Auslastung der Einrichtung in Grundlast. With the device described above, for example, a blast furnace gas fed to the inlet of the steam generator is cooled from 600 ° C. to 180 ° C. and produces a heat quantity of approximately 8.0 MWh at a melting capacity of 36 t / h. About 15% of this is converted into mechanical work by the screw compressors. By utilizing the waste heat from the steam turbine, the energy supplied is further utilized. As a result, the overall benefit increases significantly compared to the benefit of previous solutions. The compressed air operation, which is permanently high in such an operation, permits the total removal of the compressed air generated and the utilization of the facility in base load.
