Description

Die Flugasche von Kohlestaubfeuerungen kann erhebliche Mengen (zwischen'2 und 250/0) unverbrannte Kohlebestandteile enthalten. Die tSberwachung der hierdurch entstehenden Kesselverluste und das richtige Einstellen der Kesselfeuerung kann nur bei laufender Anzeige des Gehaltes an Unverbranntem in der Asche zuverlässig erfolgen. The fly ash from pulverized coal furnaces can contain considerable amounts (between '2 and 250/0) contain unburned coal components. The monitoring of this resulting boiler losses and the correct setting of the boiler firing only reliable if the content of unburned matter in the ashes is continuously displayed take place.

Die Kontrolle wird üblicherweise durch die sog. The control is usually carried out by the so-called.

Streifenprobe oder durch eine Probeentnahme in bestimmten Abständen und Behandlung derselben mit Sauerstoff vorgenommen.Strip sample or by taking a sample at certain intervals and treating the same with oxygen.

Die Vorrichtung gemäß der Erfindung gestattet eine laufende Anzeige des Gehaltes von Unverbranntem in der Flugasche. Ein bekannter Teil des Aschenstromes durchläuft hierbei einen beheizten Luft- oder Sauerstoffstrom, wodurch die unverbrannten Teile zu CO2 nachverbrannt werden. Die Menge des in der Zeiteinheit entstehenden CO2 wird durch einen CO2-Messer ermittelt und ist ein Maß für den Gehalt an Unverbranntem in der Asche. The device according to the invention allows a continuous display the content of unburned matter in the fly ash. A well-known part of the ash stream runs through a heated stream of air or oxygen, which causes the unburned Parts are post-burned to CO2. The amount that arises in the unit of time CO2 is determined by a CO2 meter and is a measure of the amount of unburned matter in the ashes.

In der Figur ist eine Ausführungsform des Erfindungsprinzips dargestellt. In das in diesem Beispiel senkrecht angeordnete, durch die Heizwicklung 2 von außen beheizte Rohr 1 tritt an der-Stelle 3 ein Teilstrom der Asche ein. Aus der Sauerstoffflasche 4 wird über die Leitung 5 von unten her Sauerstoff in das Rohr eingeblasen. Das Rohr I mündet an seinem unteren Ende in einen Aschenkasten 6. An der Stelle 7 ist eine Einschniirung angebracht, die verhindert, daß eine zu große Menge Asche in das Verbrennungsrohr I fällt. Damit sich in dieser Einschnürung das Rohr nicht verstopft, ist dort ein elektromagnetisch betriebener Rüttler 8 angeordnet. An der Stelle g befindet sich -der Leitungsanschluß des CO2-Messers IO, der die bei der Verbrennung im Rohr entstandenen CO2-Mengen anzeigt. Die Skala dieses Meßgerätes kann direkt in Prozenten der unverbrannten Bestandteile geeicht werden. In the figure, an embodiment of the principle of the invention is shown. In the one arranged vertically in this example, through the heating winding 2 from the outside heated pipe 1 occurs at the point 3, a partial flow of the ash. From the oxygen bottle 4, oxygen is blown into the pipe from below via line 5. That Pipe I opens at its lower end into an ash pan 6. At point 7 is a circlet was made to prevent too large a quantity of ashes from entering the combustion tube I falls. So that the pipe does not become clogged in this constriction, an electromagnetically operated vibrator 8 is arranged there. At the point g there is -the line connection of the CO2 meter IO, which is during the combustion shows the amount of CO2 created in the pipe. The scale of this measuring device can be directly be calibrated as a percentage of the unburned components.

PATENTANSPRtJCHE : 1. Vorrichtung zur Anzeige des Gehaltes von Unverbranntem in der Flugasche, dadurch gekennzeichnet, daß ein bekannter Teil des Aschenstromes einen beheizten Luft- oder Sauerstoffstrom durchläuft und hierbei die unverbrannten Kõhleteile zu CO2 nachverbrannt werden und daß die Menge des in der Zeiteinheit entstehenden CO2 durch einen CO2-Messer ermittelt wird. PATENT CLAIMS: 1. Device for displaying the content of unburned matter in the fly ash, characterized in that a known part of the ash flow a heated air or oxygen flow passes through and thereby the unburned Cooling parts are afterburned to CO2 and that the amount of in the time unit resulting CO2 is determined by a CO2 meter.
