Patentiert im Deutschen Reiche vom 10. März 1912 ab.Patented in the German Empire on March 10, 1912.
Die Erfindung betrifft ein Verfahren zur Feststellung der unvollkommenen Verbrennung von Feuerungsgasen mittels einer katalytischen Substanz, die von den Verbrennungsgasen durchströmt wird und wobei letztere eine Temperaturerhöhung erfahren.The invention relates to a method for determining the imperfect combustion of combustion gases by means of a catalytic substance that of the combustion gases is flowed through and the latter experience a temperature increase.
Das Wesen der Erfindung ist nun darin zu erblicken, daß die Gase innerhalb der katalytischen Substanz einer NachverbrennungThe essence of the invention can now be seen in the fact that the gases within the catalytic Substance of an afterburning
ίο unterworfen werden und die aus derselben resultierende Temperaturerhöhung gemessen wird. Zur Durchführung des Verfahrens bedarf es einer dauernd gleichmäßig arbeitenden und sehr empfindlichen Vorrichtung, da man es in den Rauchgasen mit sehr geringen Mengen Wasserstoff und hauptsächlich mit Kohlenoxyd, Methan und anderen Kohlenwasserstoffen zu tun hat, die nur bei erhöhter Temperatur mit dem Katalysator in Reaktion treten.ίο be subjected to and resulting from the same resulting temperature increase is measured. To carry out the procedure requires it is a constantly working and very sensitive device, since one it in the flue gases with very small amounts of hydrogen and mainly with carbon oxide, Methane and other hydrocarbons do that only at elevated temperature react with the catalyst.
Auf der beiliegenden Zeichnung ist beispielsweise ein geeigneter Apparat zur Durchführung des Verfahrens schematisch veranschaulicht, und zwar besteht derselbe im wesentliehen aus einem palladinierten Platinnetz a als Katalysator, das zwischen zwei Thermoelementen oder Thermobatterien b und c angeordnet ist, die gegeneinander geschaltet und an ein Galvanometer d angeschlossen sind.In the accompanying drawing, for example, a suitable apparatus for carrying out the process is schematically illustrated, namely the same essentially consists of a palladium-plated platinum network a as a catalyst, which is arranged between two thermocouples or thermal batteries b and c, which are connected to one another and connected to a galvanometer d are connected.
Der Katalysator und die beiden Thermoelemente werden zweckmäßigerweise durch einen geeigneten Heizkörper, z. B. einen Heraussehen Heizapparat, bis auf eine Temperatur von 300 bis 400° erhitzt, der derart angeordnet ist, daß die von ihm nach außen strahlende Wärme von einem Schlangenrohr e aufgenommen wird, durch das die zugeleiteten Rauchgase streichen; wobei sie vorgewärmt werden. Die Rauchgase verfolgen den in der Zeichnung durch Pfeile angedeuteten Weg.The catalyst and the two thermocouples are expediently through a suitable heating element, e.g. B. a look out heater, heated to a temperature of 300 to 400 °, which is arranged such that the heat radiating from it to the outside is absorbed by a coiled pipe e through which the supplied flue gases sweep; whereby they are preheated. The smoke gases follow the path indicated by arrows in the drawing.
Die Arbeitsweise der Vorrichtung ist folgende :The operation of the device is as follows:
Solange vor und hinter dem Katalysator, also an den Lötstellen beider Thermoelemente ein gewisser, durch die Verdichtung nicht brennbarer Gase am Katalysator bewirkter, sehr geringer Unterschied der Temperaturen herrscht, deren absolute Höhe gleichgültig ist, gibt das mit den gleichnamigen Polen verbundene Galvanometer den entsprechenden Minimalausschlag, der als Nullpunkt bezeichnet wird und einem Normalzustand der Feuerung entspricht. Eine durch die Nachverbrennung im Katalysator eintretende größere Temperaturerhöhung und die in Verbindung mit der Durchströmung der brennbaren Gase entstehende größere Temperaturdifferenz ergibt jedoch unmittelbar einen größeren elektromotorischen Kraftunterschied der beiden Thermoelemente, der durch das Galvanometer sofort angezeigt wird. Durch den Ausschlag der Magnetnadel des Galvanometers ist es möglich, kontinuierlich festzustellen, wieviel brennbare Produkte mit den Abgasen entweichen, und die Feuerung entsprechend zu regeln, d. h. sowohl den gerade der Anlage entspre-As long as in front of and behind the catalytic converter, i.e. at the soldering points of both thermocouples a certain, caused by the compression of non-flammable gases at the catalytic converter, there is very little difference in temperatures, the absolute level of which is irrelevant, the galvanometer connected to the poles of the same name gives the corresponding minimum deflection, which is called the zero point and corresponds to a normal state of the furnace. One through the afterburning occurring in the catalyst larger temperature increase and in connection with the When the flammable gases flow through, there is a greater temperature difference but immediately a larger electromotive force difference between the two thermocouples, which is immediately displayed by the galvanometer. The deflection of the galvanometer's magnetic needle makes it possible to continuously determining how much flammable products are escaping with the exhaust gases, and to regulate the firing accordingly, d. H. both the corresponding to the system
