Description
Die vorliegende Erfindung bezieht sich allgemein auf das Gebiet der jahreszeitlich konfigurierbaren Heizkraftwerksysteme mit kombiniertem Zyklus und insbesondere auf ein Kraftwerk dieses Typs, das heißes Wasser für eine Heißwassernutzvorrichtung wie z. B. ein Fernwärmesystem zur Verfügung stellt.The The present invention relates generally to the field of Seasonally configurable combined heat and power plant systems Cycle and in particular to a power plant of this type, the hot water for one Heißwassernutzvorrichtung such as B. a district heating system to disposal provides.
In einem Heizkraftwerk mit kombiniertem Zyklus wird Wärme, die in den heißen Abgasen enthalten ist, welche von einer einen Generator antreibenden Gasturbine erzeugt werden, einem Wärmerückgewinnungs-Dampfgenerator (HRSG) zugeführt, der Dampf erzeugt, der einer Dampfturbine zugeführt wird, die zusätzliche Leistung erzeugt. Diese Anordnung kann eingesetzt werden, wenn das Kraftwerk mit einer Heißwassernutzvorrichtung wie z. B. einem Fernwärmesystem ausgestattet ist. Letzteres ist ein System, das Wärme auf niedrigem Niveau für Raumheizung und/oder leichte industrielle Zwecke verwendet, wobei ein bedeutender Aspekt desselben eine jahreszeitliche Veränderung der vom System beanspruchten Wärmelast ist.In a Combined Cycle Combined Heat will heat up in the hot Exhaust gases is contained, which of a generator driving a Gas turbine to be generated, a heat recovery steam generator Supplied (HRSG), generates the steam that is fed to a steam turbine, the additional Power generated. This arrangement can be used when the Power plant with a hot water utility device such as B. a district heating system Is provided. The latter is a system that absorbs heat low level for Space heating and / or light industrial uses, where a significant aspect of it is a seasonal change the heat load required by the system is.
Bei dem obenbeschriebenen herkömmlichen Kraftwerk wird Dampf aus einer Zwischenstufe der Dampfturbine entnommen und der Heißwassernutzvorrichtung zugeführt. Das verbrauchte, gekühlte Wasser, das von der Heißwassernutzvorrichtung erzeugt wird, wird gemeinsam mit Kondensat, das von einem Kondensator erzeugt wird, durch den das Abgas der Dampfturbine geleitet wird, zum HRSG zurückgeführt, um den Wasserkreislauf zu schließen.at the conventional one described above Power plant steam is taken from an intermediate stage of the steam turbine and the hot water utilization device fed. The consumed, cooled Water coming from the hot water utility is generated together with condensate, which is from a condenser is generated, through which the exhaust gas of the steam turbine is passed, returned to the HRSG to close the water cycle.
Bei einer solchen herkömmlichen Anordnung bestehen mehrere Probleme. Erstens sind HRSGs und Dampfturbinen in erster Linie aufgrund der verwendeten Drücke zur Maximierung des thermischen Wirkungsgrades relativ kompliziert und somit hinsichtlich der Investitionskosten und der Wartung relativ teuer. Außerdem sind die Systemsteuerungen und Operationen kompliziert, um eine angepaßte und sichere Steuerung der Dampfturbine in Kombination mit der Heißwassernutzvorrichtung sicherzustellen. Die Wasserbehandlung ist maßgeblich für einen stationären Ganzjahresbetrieb. Schließlich werden die erforderlichen Steuerungen noch komplizierter, wenn die von der Heißwassernutzvorrichtung benötigte Wärmemenge jahreszeitlich schwankt.at such a conventional one Arrangement there are several problems. First are HRSGs and steam turbines primarily due to the pressures used to maximize the thermal Efficiency relatively complicated and thus in terms of investment costs and maintenance relatively expensive. In addition, the system controls and operations complicated to a customized and safe control of the steam turbine in combination with the hot water utilization device sure. Water treatment is essential for a stationary year-round operation. After all The necessary controls become even more complicated when the from the hot water utilization device needed heat seasonally fluctuates.
Es ist daher die Aufgabe der vorliegenden Erfindung, ein neuartiges und verbessertes Heizkraftwerk mit kombiniertem Zyklus zu schaffen, das einfacher und kostengünstiger aufzubauen und zu betreiben ist als Kraftwerke des Standes der Technik.It is therefore the object of the present invention, a novel and to create a combined cycle combined heat and power plant the easier and cheaper To build and operate is as power plants of the prior art.
