Description
Verfahren zur Kühlung von Kondensationskraftwerken undProcess for cooling condensing power plants and
Äbwärmenutzung.Use of waste heat.
Bei der Erzeugung von elektrischem Strom in Kondensationskraftwerken muß etwa 65% der eingesetzten Primärenergie als Abwärme an die Umwelt abgeführt werden. Diese Abwärme wird durch Austausch an die Kühlmedien der Umwelt, Wasser oder Luft, verteilt, und geht dem Prozeß der Dampfbildung und Stromerzeugung völlig verloren. Verfahren wie Frischwasser oder Nassekühlung,sowie Trockene-Rückkühlung, werden in Kühlturmen angewandt. Diese Abwärme, ist die Kondensationswärme, die dem Abdampf nach der Dampfturbine,durch Kühlung entzogen wird, um daraus Kondensat zu erzeugen.When generating electricity in condensing power plants 65% of the primary energy used must be discharged into the environment as waste heat will. This waste heat is exchanged to the cooling medium of the environment, water or air, and completely goes into the process of steam formation and electricity generation lost. Processes such as fresh water or wet cooling, as well as dry recooling, are used in cooling towers. This waste heat is the heat of condensation, which is the Exhaust steam after the steam turbine is withdrawn by cooling in order to convert it into condensate produce.
Der Wirkungsgrad des gesamten Prozeßes steigt mit sinkender Endtemperatur des Abdampfes und dadurch erzeugtes Vakuum im Kondensator.Die Temperatur und Verfügbarkeit der Kühlmedien in der Umwelt,setzen diese Notwendigkeit,je nach Ort und Jahreszeit,physikalische und wirtschaftliche Grenzen.The efficiency of the entire process increases as the final temperature falls of the exhaust steam and the resulting vacuum in the condenser. The temperature and availability of the cooling media in the environment, this necessity, depending on the location and time of year, is physical and economic limits.
Die Erfindung betrifft ein Verfahren,wobei ,die Abkühlung des Abdampfes unabhängig von den Umweltbedingungen und ohae Abwärme an die Umwelt,durch einen Gaskältekreis erfolgt.The invention relates to a method whereby the cooling of the exhaust steam regardless of the environmental conditions and ohae waste heat to the environment, by one Gas refrigeration cycle takes place.
Der Gaskältekreis besteht aus Kältekompressor mit Antrieb, Verflüssiger-Regelventil-Verdampfer-Schaltung.The gas refrigeration circuit consists of a refrigeration compressor with drive, condenser control valve and evaporator circuit.
Dem Abdampf,wird die Abwärme im Verdampfer entzogen und dem Kondensat,auf einem höhren Gemperaturniveau,im Verflüssiger zugeführt.Die Kesselspeisepumpe pumpt das Kondensat vom Verdampfer ab,drückt es durch einen Rauchgasvorwärmer und anschließend den Verflüssiger,wo das Kondensat die Vorwärmeendtemperatur erreicht,bevor es durch ein Drosselventil in die Kesselanlage eingespeist wird.The waste heat is extracted from the exhaust steam in the evaporator and fed to the condensate, at a higher temperature level, in the condenser. The boiler feed pump pumps the condensate from the evaporator, pushes it through a flue gas preheater and then the condenser, where the condensate is the preheating end temperature is reached before it is fed into the boiler system through a throttle valve.
Der Gaskältekreis,kann als einen einfacher Kreis,oder in Kaskadenschaltung zweier weise ausgeführt werden.Durch eine Kaskadensche g,kann der Abdampf bei etwa 5 C kondensieren - daß Kondensat auf eine Vorwärmeendtemperatur von etwa 100-130 C angehoben werden.Das Kondensat kann in die Kesselanlage als n eine überhitzte Flüssigkeit eingedrückt, und die Kesselanlage arbeitet nur als Dampfüberhitzer.The gas refrigeration cycle can be as a simple circuit, or in Cascade connection can be carried out in two ways. By means of a cascade circuit, the exhaust steam can condense at about 5 C - that condensate can be raised to a preheating end temperature of about 100-130 C. The condensate can be pressed into the boiler system as a superheated liquid, and the boiler system only works as a steam superheater.
Durch dieses Verfahren,ist der Abdampf zu Kondensat abgekühlt, und die Abwärme,für die Dampfbildung,auf ein höheres Temperaturniveau angehoben und zurückgewonnen.Die hierfür geleistete VerdichtungsarVeit im Antrieb des Kältekompressors,stellt nur ein Bruchteil der erzielten Energieeinsparung.With this process, the exhaust steam is cooled to condensate, and the waste heat, for the steam formation, is raised to a higher temperature level and recovered a fraction of the energy savings achieved.
Die Abwärmenutzung ist in einer Kraft/Wärme-Kopplung zu erreichen,in dem die Abwärme im Verflüssiger,ststt dem Kondensat, wahlweise, einem Fernwärmenetz überführt werdeneAbb2.The use of waste heat can be achieved in a power / heat coupling the waste heat in the condenser, the condensate, optionally, a district heating network be transferred eFig. 2.
Ein Zusatz-Verflüssiger und eine Umschaltungseinrichtung werden für diese Kopplung zusätzlich benötigt.Durch Umschaltung kann vom Winter auf Sommer-betrieb übergegangen werden. LeerseiteAn additional condenser and a switching device are used for this coupling is also required. By switching from winter to summer operation be passed over. Blank page
