Abstract

In a process for optimising the combustion mechanism in a combustion plant for fossil fuels, the moisture content of the main flow of combustion air is set, reproducibly, at a higher level than that of the ambient air and enriched with ionised oxygen before being fed into the combustion plant. The aim is to improve (optimise) the utilisation coefficient of the fossil fuel to be burned and thus the efficiency of the combustion plant itself.

Description

Verfahren zur Optimierung des Verbrennungs¬ mechanismus in einer VerbrennungseinrichtungMethod for optimizing the combustion mechanism in a combustion device
B E S C H R E I B U N GDESCRIPTION
Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Optimierung des Verbrennungsmechanismus in einerThe present invention relates to a method for optimizing the combustion mechanism in an
Verbrennungse nric tung für fossi le Brennstoffe, insbe¬ sondere zur Anwendung beim Betrieb von Wärmekraft¬ maschinen wie zum Beispiel Verbrennungsmotoren, Gas¬ turbinen und Dampferzeugern.Combustion device for fossil fuels, in particular for use in the operation of heat engines such as internal combustion engines, gas turbines and steam generators.
Auch wenn der genaue Mechanismus von Verbrennungsvor¬ gängen bis heute noch nicht vollständig aufgeklärt und verstanden ist, so läßt sich eines zweifelsfrei fest¬ stellen, nämlich daß die fossi len Brennstoffe, wie zum Beispiel öl oder Kohle, unter Zuführung von Verbren- nungsluft verbrennen und Wärmeenergie erzeugen, die dann zum Betrieb von Kra tmaschinen genutzt werden kann. In Verbindung mit Verbrennungskraftmaschinen und Ver¬ brennungsvorgängen allgemein ist auch bekannt, daß mit einer Zumischung von ionisiertem Sauerstoff zur Ver- brennungs luft eine vollständigere Verbrennung fossiler Brennstoffe erzielt werden kann; die Verbrennung wird weiter verbessert, wenn dem ionisierten Sauerstoff vor der Einleitung in die Verbrennungs luft gezielt Feuchtig¬ keit zugemischt wird. Die Verbesserung der Verbrennung an sich beruht offens chtlich darauf, daß über dieEven if the exact mechanism of combustion processes has not yet been fully elucidated and understood, one thing can be ascertained beyond doubt, namely that fossil fuels, such as oil or coal, burn with the supply of combustion air and Generate thermal energy, which can then be used to operate machines. In connection with internal combustion engines and combustion processes in general, it is also known that a more complete combustion of fossil fuels can be achieved by adding ionized oxygen to the combustion air; the combustion is further improved if the ionized oxygen is specifically mixed with moisture before being introduced into the combustion air. The improvement in combustion itself is obviously based on the fact that over the
Thermolyse des zusätzlichen Wassers einerseits und die vom ionisierten Sauerstoff bereitgestellten negativen Ionen andererseits sich ein kombinatorischer beziehungs¬ weise synerg i st i scher Effekt mit entsprechender Wir- kungsgradverbesserung ergibt (vergleiche DE-PS 24 61 694, DE-PS 27 22 431, DE-OS 32 40 651). Die der vorliegenden Erfindung zugrunde liegende Aufgabe bestehe darin, den Brenn sto -Ausnut zung sgrad der in einer Verbrennungseinrichtung zu verbrennenden fossi len Brennstoffe weiter zu verbessern.Thermolysis of the additional water on the one hand and the negative ions provided by the ionized oxygen on the other hand result in a combinatorial or synergistic effect with a corresponding improvement in efficiency (compare DE-PS 24 61 694, DE-PS 27 22 431, DE- OS 32 40 651). The object on which the present invention is based is to further improve the degree of fuel utilization of the fossil fuels to be burned in a combustion device.
Diese Aufgabe wird dadurch gelöst, daß der Verbrennungs' Haupt luftst ro auf einen reproduzierbaren, relativ zur Umgebungs luf t höheren Feucht gkeitsgehalt eingestellt wird, und daß in den so eingestellten Verbrennungs- Haupt luft st rom vor der Zuführung zur Verbrennungsein¬ richtung ionisierter Sauerstoff eingeleitet wird.This object is achieved in that the combustion main air flow is set to a reproducible moisture content which is higher relative to the ambient air, and in that ionized oxygen is introduced into the combustion main air stream before it is fed to the combustion device becomes.
Eine Weiterbi ldung dieser Grundidee besteht darin, daß der Verbrennungs-Haupt luftst rom zusätzlich angewärmt wird, und daß - wie an sich bekannt - auch dem ionisier' ten Sauerstoff Feuchtigkeit definiert zugemischt wird.A further development of this basic idea consists in that the main combustion air stream is additionally warmed, and that - as is known per se - the ionized oxygen is also admixed with moisture in a defined manner.
Im Gegensatz zum Stand der Technik wird erfindungsgemäß also nicht der den ionisierten Sauerstoff tragende be¬ ziehungsweise mitführende Gasstrom bezüglich seines Feuchtigkeitsgehalts auf einen reproduzierbaren Wert eingestellt, sondern der Verbrennungs-Haupt l uftst rom . Damit wird letztlich erreicht, daß - bezogen auf die sich aus dem Verbrennungs-Haup luft st rom und dem Gas¬ strom mit dem ionisierten Sauerstoff bi ldende Gesamtver- brennungs luft - die im Brennraum der Verbrennungsein¬ richtung verbrannte Luft insgesamt mehr positiv ge¬ ladene Wasserstoffionen H freisetzt, die dann mit den zugemischten negativ geladenen Sauerstoff i onen 0 exo¬ therm reagieren und entsprechend viel Wärmeenergie er¬ zeugen. Durch die genaue Dosierung des Feuchtigkeitsge¬ halts des Verbrennungs-Haupt luftst ro s und die Erhöhung dieses Feuchtigkeitsgehaltes relativ zur Umgebungs luf t lassen sich so exakt reproduzierbare Betriebsverhält¬ nisse und im wesentlichen vorher berechenbare Wärmemengen erreichen. Damit werden letztlich auch die mit unter¬ schiedlichen Ausgangs-Feuchtigkeiten der Umgebungs luft verbundenen Ungenaui gkei ten eliminiert.In contrast to the prior art, the moisture content of the gas stream carrying or carrying the ionized oxygen or entrained is not adjusted to a reproducible value, but the main combustion is running. This ultimately ensures that - based on the total combustion air forming from the main combustion air and the gas stream with the ionized oxygen - the air burned in the combustion chamber of the combustion device is generally more positively charged Releases hydrogen ions H, which then react with the admixed negatively charged oxygen ions 0 exotherm and generate a correspondingly large amount of thermal energy. Due to the exact metering of the moisture content of the main combustion air stream and the increase of this moisture content relative to the ambient air exactly reproducible operating conditions and essentially previously predictable amounts of heat can be achieved in this way. Ultimately, this also eliminates the inaccuracies associated with different initial humidities of the ambient air.
Eine weitere Ausgestaltung des erfindungsgemäßen Ver¬ fahrens besteht darin, den Verbrennungs-Haupt luf t st rom zusätzlich, d.h. vor der Zuführung zum Brennraum, zu erwärmen. Damit kann der Feuchtigkeitsgehalt der Ver¬ brennungsluft gezielt erhöht und der Wirkungsgrad weiter verbessert werden.A further embodiment of the method according to the invention consists in additionally adding the main combustion air, i.e. before being fed to the combustion chamber. The moisture content of the combustion air can thus be increased in a targeted manner and the efficiency can be further improved.
Darüberhinaus kann natürlich auch dem Gasstrom mit dem ionisierten Sauerstoff gezielt und definiert Feuchtig¬ keit zugemischt werden, so daß die Gesamtverbrennungs- luft exakt reproduzierbar eingestellt werden kann. Grundsätzlich besteht auch die Möglichkeit Feuchtig¬ keit mittelbar über den Brennstoff in die Flamme einzu¬ bringen oder unmittelbar direkt in die Flamme einzu- spritzen. In addition, of course, the gas stream with the ionized oxygen can be specifically and specifically admixed with moisture, so that the total combustion air can be set exactly reproducibly. In principle, there is also the possibility of introducing moisture into the flame indirectly via the fuel or of injecting it directly into the flame.
