Description
Dampf-Gas-Wärmehr aftanlage. Es sind Dampf-Gas-Wärmekraftanlagen vorgeschlagen, bei welchen die Verbrennungs gase einen Teil ihrer Wärme zur Dampferzeu gung und mindestens einen Teil der Rest wärme zur Erhitzung von Gas einer Gas turbinenanlage abgeben. Die Abwärme der Gasturbine dient zur Vorwärmung der Ver brennungsluft der Dampfanlage, so dass die Gasturbine alle ihre Wärme nutzbar abgibt und daher mit höchstmöglichem Wirkungs grad arbeitet. Dann ist aber auch der Lei stungsanteil der Gasturbinenanlage bestimmt durch die Grösse der Verbrennungsluftmenge und durch das Temperaturgefälle.
Aus die sem Grunde sind die bekannten Vorschläge nicht zur Ausführung. gelangt; denn die.er reichbare Leistung der Gasturbinenanlage ist zu klein, um die Mehrkosten wirtschaftlich zu decken.
Die vorliegende Erfindung beseitigt obigen Nachteil dadurch, dass das Gas der Gasturbine durch die Verbrennungsgase zwi schenüberhitzt wird. Es steigt dadurch der Leistungsanteil der Gasturbinenanlage. Wird zudem die Gasmenge nach grösser gewählt, als zur Vorwärmung der Verbrennungsluft nötig ist, so kann ihr Leistungsanteil noch weiter gesteigert werden.
Die beiliegende Zeichnung zeigt schema tisch ein Ausführungsbeispiel des Erfin dungsgegenstandes. 1 bezeichnet den Dampf kessel, 2 die Zuleitung des Speisewassers. 4 ist ein Dampfüberhitzer; der Dampf strömt durch eine Leitung 5 zu einer Gegendruck turbine 6 mit Nutzleistungsmaschine 9. Es sind zwei Roste 31 und 32 vorhanden. Der Abdampf strömt aus der Turbine 6 durch die Leitung 7 zu den Verbrauchsstellen. Die Pumpe 8 drückt das Speisewasser durch die Vorwärmer 101 und 102 zum Kessel. Die Luftturbine besteht aus zwei Teilen.
Der Verdichter 14 drückt die Luft durch den .Lufterhitzer 12, zur Hochdruckturbine 181. Hierauf strömt die Druckluft zum Zwischen- überhitzer 122 und zur Niederdruckturbine 132 mit Nutzleistungsmaschine 15. Die Abluft strömt zum Teil durch die Leitung 16 als Verbrennungsluft zu den Rosten 31 und 32, zum Teil durch die Leitung 17 zum Speise wasservorwärmer 101. Sofern nach dem Vor wärmer 101 noch weitere Wärme verfügbar ist,- kann die Restluft noch zu weiteren Wärmezwecken verwendet werden.
Der Einbau des Dampfüberhitzers und der Lufterhitzer kann auch auf beliebig andere Art erfolgen; so können zum Beispiel die Lufterhitzer auch neben dem Dampf kessel aufgestellt werden.
Durch die Zwischenüberhitzung wird der Luftturbinenanlage mehr Wärme zugeführt und damit die Leistung derselben und der Gesamtanlage vergrössert gegenüber einer Luftturbinenanlage ohne Zwischenüberhit zung.
Es kann auch Luft oder Gas in einem geschlossenen Kreislauf geführt und erhitzt werden. Nach dem Arbeiten der Druckluft oder des Druckgases in einer Luft- oder Gas- turbine wird die Abluft oder das Abgas die Restwärme mindestens zum Teil in einem Wärmeaustauscher an die Verbrennungsluft oder zu andern Wärmezwecken abgeben.
Die Abluft aus der Luftturbine kann mindestens einen Teil ihrer Wärme auch zur Vorwärmung der Druckluft nach dem Aus tritt aus dem Verdichter abgeben.
Steam-gas heating system. There are steam-gas thermal power plants proposed in which the combustion gases give off part of their heat for Dampferzeu generation and at least part of the remaining heat for heating gas from a gas turbine system. The waste heat from the gas turbine is used to preheat the combustion air in the steam system so that the gas turbine can use all of its heat and therefore works with the highest possible efficiency. But then the power share of the gas turbine system is also determined by the size of the amount of combustion air and the temperature gradient.
For this reason, the known proposals are not for implementation. arrives; because the achievable power of the gas turbine system is too small to cover the additional costs economically.
The present invention eliminates the above disadvantage in that the gas of the gas turbine is inter-superheated by the combustion gases. This increases the power share of the gas turbine system. If, in addition, the amount of gas selected is greater than is necessary to preheat the combustion air, its share of performance can be increased even further.
The accompanying drawing shows schematically an embodiment of the subject of the invention. 1 denotes the steam boiler, 2 the feed line for the feed water. 4 is a steam superheater; the steam flows through a line 5 to a counter-pressure turbine 6 with a power machine 9. There are two grids 31 and 32 available. The exhaust steam flows from the turbine 6 through the line 7 to the consumption points. The pump 8 pushes the feed water through the preheaters 101 and 102 to the boiler. The air turbine consists of two parts.
The compressor 14 pushes the air through the air heater 12 to the high pressure turbine 181. The compressed air then flows to the intermediate superheater 122 and to the low pressure turbine 132 with the power machine 15. The exhaust air partly flows through the line 16 as combustion air to the grates 31 and 32 , partly through the line 17 to the feed water preheater 101. If further heat is available after the preheater 101, - the remaining air can still be used for further heating purposes.
The steam superheater and the air heater can also be installed in any other way; For example, the air heater can also be installed next to the steam boiler.
As a result of the reheating, more heat is supplied to the air turbine system and thus the output of the same and of the entire system is increased compared to an air turbine system without reheating.
Air or gas can also be fed and heated in a closed circuit. After the compressed air or the compressed gas has worked in an air or gas turbine, the exhaust air or the exhaust gas will at least partially release the residual heat in a heat exchanger to the combustion air or for other heating purposes.
The exhaust air from the air turbine can release at least part of its heat to preheat the compressed air after it exits the compressor.
