Gegenstand vorliegender Erfindung ist ein Verfahren zur Ausnutzung der Abwärme von Gas- oder Gasdampfturbinen, welche durch die gespannten Verbrennungsprodukte eines unter Druck verbrennenden Brennstoffluftgemisches, nachdem dieselben durch Wärmeabgabe an das Wasser in einem Dampfkessel auf die zur Beaufschlagung der Turbine vorteilhafte Temperatur abgekühlt sind, betrieben werden.The present invention is a method for utilizing the waste heat from Gas or gas steam turbines, which by the stressed combustion products of an under Pressure-burning fuel-air mixture after the same by giving off heat the water in a steam boiler to the advantageous for acting on the turbine Temperature have cooled down.
ίο An Hand der Zeichnung, welche beispielsweise die Gesamtanordnung einer zur Ausführung des Verfahrens geeigneten Vorrichtung darstellt, soll das Verfahren erläutert werden.ίο On the basis of the drawing, which for example represents the overall arrangement of a device suitable for carrying out the method, the method is intended to be explained will.
Gas und Luft werden, beständig unter Druck zuströmend, in einem Rohr a, welches in einen Kessel U eingebaut ist, verbrannt. Die Verbrennungsprodukte, welche beispielsweise zuerst einen Druck von 7 Atm. und eine Temperatur von 15000 haben, kühlen sich beim Durchstreichen des Heizrohres auf ein gewünschtes Maß ab (beispielsweise auf 600 °), während der durch die Wärmeabgabe entwickelte Dampf (mit beispielsweise 7 Atm.Gas and air, constantly flowing in under pressure, are burned in a pipe a, which is built into a boiler U. The products of combustion, which, for example, first have a pressure of 7 Atm. and have a temperature of 1500 0 , cool down to a desired level (for example to 600 °) when passing through the heating pipe, while the steam developed by the heat release (for example 7 atm.
und i8o°), von den Gasen getrennt, aus dem Kessel entweicht. Gase und Dämpfe können nun außerhalb des Kessels entweder vereinigt oder getrennt zur Arbeitsleistung herangezogen werden, in dem dargestellten Aus- führungsbeispiel werden sie zunächst durch einen Überhitzer geleitet, in welchem die. Gase beispielsweise auf 5000 abgekühlt, die Dämpfe auf 350° erwärmt werden. Die Gase treten alsdann arbeitsleistend in die Turbine T, der Dampf in die Dampfmaschine M. and 18o °), separated from the gases, escapes from the boiler. Gases and vapors can now either be combined or used separately for work outside the boiler. In the exemplary embodiment shown, they are first passed through a superheater in which the. Gases, for example, cooled to 0 500, the vapors are heated to 350 °. The gases then enter the turbine T to perform work, the steam into the steam engine M.
Hier setzt nun die Erfindung ein. Es sollen die aus der Gasturbine entweichenden, ^4 noch hoch erhitzten Abgase durch den Dampfkessel, welcher von den verbrannten Gasen beheizt wird, zurückgeleitet werden und dort einen Teil ihrer Wärme zur Dampfbildung ' abgeben, also die Wirkung des Heizrohres a unterstützen. In der Ausführungsform ist angenommen, daß die Temperatur der Gase im Kessel bis auf 2000 sinkt (was bei der angenommenen Temperatur des Kesselwassers von i8o° möglich ist) und dann schließlich noch einen Speisewasservorwärmer V durchströmen, in welchen das aus der Kondensationsdampfmaschine M abfließende Kondenswasser bei Sp mit 40° eintritt, um dann U nach Vorwärmung mit möglichst nahe an ioo° in den Kessel weiter gepumpt zu werden. Die Ausnutzung der Abwärme in ahnlicher Weise ist bereits für Dampfturbinen bekannt, besondere Vorteile bietet diese Wärmeausnutzung jedoch, wenn sie in einem Verbrennungskreislauf Verwendung findet, weil alsdann die Volumenvergrößerung des 60, Verbrennungsgemisches arbeitsleistend mit in , den Kreislauf eingreift. Es mag zur grundsätzlichen Unterscheidung von älteren Verfahren bemerkt werden, daß es sich im vorliegenden Falle im Gegensatz zu jenen, welche nur einen Kreislauf der erzeugten Dämpfe betreffen, um einen Kreislauf der dampferzeugenden Verbrennungsgase handelt, denen This is where the invention comes in. It should be returned to the escaping from the gas turbine, ^ 4 is still highly heated exhaust gases through the steam boiler, which is heated by the burnt gases and there their heat for steam generation 'to leave a part, that support the effect of the heat pipe a. In the embodiment, it is assumed that the temperature of the gases in the boiler to 200 0 lowers (which is ° is possible by i8o at the assumed temperature of the boiler water) and then finally to flow through another feed water V in which the effluent from the condensation of steam engine M condensation occurs at Sp at 40 °, in order then, after preheating, to be pumped further into the boiler at as close as possible to 100 °. The utilization of waste heat in a similar way is already known for steam turbines, but this utilization of heat offers particular advantages if it is used in a combustion cycle, because the increase in volume of the combustion mixture then intervenes in the cycle to provide work. In order to make a fundamental distinction from older processes, it may be noted that in the present case, in contrast to those which only concern a cycle of the generated vapors, a cycle of the steam-generating combustion gases is concerned
allerdings die erzeugten Dämpfe vollständig oder zum Teil beigemischt sein können.however, the vapors generated can be wholly or partially admixed.
