Der Grundgedanke der Erfindung liegt mit anderen Worten darin, dass für bekannte Arten von Brennmaterial, insbesondere bekannte Kohlesorten, charakteristische Verteilungen, insbesondere zweidimensionale Verteilungen, für die Konzentra-tion mindestens eines Stoffes im Abgas und/oder für die Temperatur im Verbrennungsraum ermittelt werden können. Anhand solcher charakteristischer Verteilungen ist ein Erkennen der Art des Brennmaterials und insbesondere der Kohlesorte möglich. Nachfolgend kann die erkannte Art bzw.

On the basis of such characteristic distributions, a recognition of the type of fuel and in particular the type of coal is possible. Subsequently, the recognized species or variety can then be taken into account in the regulation of combustion and in particular in the automatic switching of control parameters, such as the excess air, advantageously for reducing pollutant emissions and for reducing fuel consumption.
Bei der obigen Definition der Erfindung wird unter "Stoff" allgemein jede Art von Verbrennungsprodukt verstanden, insbesondere in Form von Gas als Bestandteil des Abgases. Ferner wird unter dem Begriff Brennmaterial jede Art von Material verstanden, welches bei Kraftwerken zur Verbrennung gelangt.

Furthermore, the term fuel is understood to mean any type of material which is incinerated in power plants. For the presently particularly relevant coal-fired power plants, these are different types of coal or different types of coal.
Beim Rückschließen auf die Art von Brennmaterial wird ein Vergleich zwischen einer mit einem Musterbrennmaterial ermittelten Konzentrationsverteilung des Stoffes bzw. einer ermittelten Temperaturverteilung und der gemessenen realen Konzentrationsverteilung bzw. Temperaturverteilung vorgenommen.When inferring on the type of fuel, a comparison is made between a determined with a pattern fuel concentration distribution of the substance or a determined temperature distribution and the measured real concentration distribution or temperature distribution.

So it is not necessarily a sequential procedure when measuring concentration / s and the temperature and more
Rückschließen auf die Art des Brennmaterials erforderlich, sondern es können diese Schritte auch simultan erfolgen, so dass die erfindungsgemäßen Rückschlüsse besonders schnell und besonders aussagekräftig erzeugt werden können. Insgesamt kann so auf einfache Weise eine zwar nur genäherte, dafür aber sehr zeitnahe Erkennung der Art des Brennmaterials auf kostengünstige, einfache und zugleich prozesssichere Art erzielt werden.Feedback on the type of fuel required, but it can also be done simultaneously, so that the conclusions according to the invention can be generated very quickly and particularly meaningful.

Fig. 2 ein Ausführungsbeispiel des erfindungsgemäßen Verfahrens .Fig. 2 shows an embodiment of the method according to the invention.
In Fig. 1 ist ein Verbrennungsraum 10 eines weiter nicht veranschaulichten Kohlekraftwerks dargestellt, in dem beim Betrieb des Kohlekraftwerkes ein Kohlefeuer brennt. In dem Verbrennungsraum 10 befinden sich dabei das Brennmaterial Kohle mit zugehörigen Brenngasen, mehrere Flammen 11 sowie Abgase.In Fig. 1, a combustion chamber 10 of a not further illustrated coal power plant is shown in which burns a coal fire during operation of the coal power plant. In the combustion chamber 10 are the fuel coal with associated fuel gases, multiple flames 11 and exhaust gases.
Im Verbrennungsraum 10 sind horizontal und parallel zu einander zwei Messebenen 12 und 14 vorgesehen, an deren Umfangsrand sich beabstandet voneinander jeweils mehrere Messinstrumente 16 befinden. Jeweils zwei der Messinstrumente 16 ermöglichen eine linienförmige Messung in der zugehörigen Messebene 12 bzw. 14, wobei mit Hilfe der Messinstrumente 16 und einer zugehörigen Auswerteeinrichtung 18 die Konzentration der Stoffe O2 (Sauerstoff) und CO (Kohlenmonoxid) gemessen werden können.In the combustion chamber 10, two measuring planes 12 and 14 are provided horizontally and parallel to each other, at the Peripheral edge spaced from each other several measuring instruments 16 are located. In each case two of the measuring instruments 16 allow a linear measurement in the associated measuring plane 12 or 14, wherein the concentration of the substances O2 (oxygen) and CO (carbon monoxide) can be measured with the aid of the measuring instruments 16 and an associated evaluation device 18.
Ferner kann mit den Messinstrumenten 16 und der Auswerteeinrichtung 18 die Temperaturverteilung in der zugehörigen Messebene 12 bzw. 14 ermittelt werden. Die Messung beruht dabei auf einer Kombination von Messtechnik und CAT-Berechnung .Furthermore, the temperature distribution in the associated measuring plane 12 or 14 can be determined with the measuring instruments 16 and the evaluation device 18.

Die Auswerteeinrichtung 18 ist über einen Datenbus 20 mit einer Optimierungseinrichtung 22, einer Bedieneinrichtung 24 und einer Leiteinrichtung bzw. Leittechnik 26 betrieblich derart gekoppelt. Über die Bedieneinrichtung 24 können die von der Auswerteeinrichtung 18 gemessenen realen Konzentrationsverteilungen sowie Temperaturverteilungen in den Ebenen 12 und 14 dazu genutzt werden, dass die Optimierungseinrichtung 22 daraus auf die Art des im Verbrennungsraum 10 aktuell verbrannten Brennmaterials, vorliegend auf die dortige Kohlesorte, schließt.The evaluation device 18 is operationally coupled via a data bus 20 with an optimizing device 22, an operating device 24 and a guide or control system 26. By means of the operating device 24, the real concentration distributions measured by the evaluation device 18 and temperature distributions in the planes 12 and 14 can be used for the optimization device 22 to deduce therefrom the type of combustion material currently burned in the combustion chamber 10, in this case the local type of coal.
Die Art des Brennmaterials wird ermittelt, um die in dem Verbrennungsraum 10 brennenden Flammen 11 insbesondere im Hinblick auf einen geringen Ausstoß von NOx (Stickoxid) zu optimieren .The type of fuel is determined in order to optimize the burning in the combustion chamber 10 flames 11, in particular with regard to a low emission of NO x (nitrogen oxide).
Zur Ermittlung der Art des Brennmaterials verwendet die Optimierungseinrichtung 22 gespeicherte, charakteristische Muster der Konzentrationen der genannten Stoffe im Abgas und der Temperatur, welche mit Referenz-Brennmaterialien ermittelt und in der Optimierungseinrichtung 22 gespeichert worden sind. Die real gemessenen Verteilungen der Konzentration und der Temperatur werden mit diesen Mustern verglichen und mit dem derartigen Vergleich Übereinstimmungen erkannt .To determine the nature of the fuel, the optimizer 22 uses stored, characteristic patterns of the concentrations of said substances in the exhaust gas and the temperature, which have been determined with reference fuel and stored in the optimizer 22. The real measured distributions of the concentration and the temperature become with these patterns compared and recognized with the comparison of similarities.
Das zugehörige Verfahren ist in Fig. 2 veranschaulicht. Es umfasst den Schritt 28 des Messens der Konzentrationsverteilung z. B. der Stoffe O2 und CO und der Temperaturverteilung in der Ebene 12. Im Schritt 30 wird zeitgleich die Konzentrationsverteilung z. B. der Stoffe O2 und CO in der Ebene 14 sowie die dortige Temperaturverteilung gemessen. Im Schritt 32 wird, wie oben erläutert, die Konzentrationsverteilung sowie die Temperaturverteilung in den Ebenen 12 und 14 derart ausgewertet, dass auf die Art des Brennmaterials im Verbrennungsraum 10 rückgeschlossen werden kann .The associated method is illustrated in FIG. It comprises the step 28 of measuring the concentration distribution z. As the substances O 2 and CO and the temperature distribution in the plane 12. In step 30, the concentration distribution z. B. the substances O 2 and CO in the plane 14 and the local temperature distribution measured. In step 32, as explained above, the concentration distribution and the temperature distribution in the planes 12 and 14 are evaluated in such a way that the nature of the fuel in the combustion chamber 10 can be deduced.
Auf der Grundlage dieses Rückschlusses erfolgt dann in einem Schritt 34 eine Optimierung der Verbrennung, beispielsweise durch eine Änderung der Luftschichtung und/oder ein abschnittsweises Ändern des Luftüberschusses. On the basis of this inference then takes place in a step 34, an optimization of the combustion, for example, by a change in the air stratification and / or a section-wise changing the excess air.
