Einrichtung zur Messung der Temperatur von strömenden GasenDevice for measuring the temperature of flowing gases

Die Erfindung betrifft eine Einrichtung zur Messung der Temperatur von strömenden Gasen in Rohrleitungen, ins"besondere der Heißwindtemperatur "beim Betrieb von Hochöfen. Für die Regelung der LÜschwindtemperatur an Hochöfen muß f die Windtemperatur möglichst verzögerungsfrei gemessen werden. Bisher wurden dafür in den Windstrom ragende Thermoelemente eingesetzt, beispielsweise nackte Nickel-Chrom-Nickel -Elemente, die geringe Anzeigeverzogerung haben. Diese Elemente sind aber nur bis zu Windtemperaturen vonThe invention relates to a device for measuring the temperature of flowing gases in pipelines, in particular the hot blast temperature "when operating blast furnaces. For the control of the LÜschwind temperature at blast furnaces f the wind temperature can be measured with as little delay as possible. So far, thermocouples protruding into the wind power were used for this used, for example bare nickel-chromium-nickel -Items that have low display lag. These elements are only up to wind temperatures of

Es bestellt die Aufgabe, eine Einrichtung zur Messung der Heißwindtemperatur zu schaffen, die bei möglichst kleiner Anzeigeverzögerung in allen technisch vorkommenden Temperaturbereichen eingesetzt werden .kann. Diese Aufgabenοteilung gilt auch für die Temperaturnessung anderer Gase hoher Temperatur. Zur lösung dieser Aufgabe wird eine Einrichtung vorgeschlagen, die dadurch gekennzeichnet ist, daß in der Wand des gasführenden Kanals ein in den Gasstrom ragender Heßkörper aus temperaturfesten, schlecht wUrneleitendem Material angebracht ist, und daß ihm gegenüber ein Pyroneter angeordnet ist zur Messung der der Gastenperatur entsprechenden Temperatur einer Meßfläche des Ivleßkörpers. Der Meßkörper soll möglichst die Eigenschaften eines schwarzen Strahlers aufweisen. Infolge der schlechten Wärmeleitung nimmt seine Oberfläche sehr schnell die Temperatur des zu messenden Gases an. Wird der Meßkörper als Hohlkörper ausgebildet,, so folgt seine Oberflächentemperatur noch schneller den Änderungen der Gastenperatur. Da die pyrometrie ehe Ilessung praktisch verzögerungsfrei erfolgt, folgt die Ileßeinrichtung schneller als alle bisher bekannten Meßeinrichtungen den Änderungen der Gantemperatur.approx. 1000 ° C usable. It ordered the task of creating a device for measuring the hot blast temperature, with the smallest possible display delay in all technical occurring temperature ranges are used .can. This division of tasks also applies to temperature measurement other high temperature gases. To solve this problem, a device is proposed that thereby is characterized in that in the wall of the gas-carrying channel a Hßkörper protruding into the gas flow made of temperature-resistant, bad heat-conducting material is attached, and that A pyroneter is arranged opposite it for measuring the temperature of a measuring surface corresponding to the guest temperature of the obesity. The measuring body should, if possible, have the properties of a black body. As a result of the poor heat conduction, its surface increases very quickly the temperature of the gas to be measured. If the measuring body is designed as a hollow body, its surface temperature follows changes in guest temperature even faster. As the pyrometry before reading is practically instantaneous takes place, the measuring device follows the changes faster than all previously known measuring devices the gant temperature.

In den Heißwindkanal 1 einer Hochofenanlage strömt der Heißwind in der durch den Pfeil angegebenen Richtung. In der Innenwand des Heißwindkanals 1 ist ein Heßkörper 2 aus keramischem, εchi echt wärmeleitendem Material so angeordnet, daß er teilweise in den Heißwindstrom ragt. Ihm gegenüber ist in der Wand des Heißwindkanals 1 eine Öffnung 3 angebracht, in der ein Visierrohr 4 für das Pyrometer 5 befestigt ist. LIit dem mit photoelektrischen Empfängern arbeitenden Pyrometer 5 wird die Oberfläche 6 des Itleßkörpers 2 anvisiert. Die Oberfläche 6 ist leicht gegen die Strömungsrichtung geneigt, wodurch erreicht wird, daß diese Oberfläche besonders schnell die Windtemperatur annimmt. Um das Pyrometer 5 ohne Betriebsunterbrechung abnehmen oder auswechseln zu können, besteht die Ilöglichkeit, das Visierrohr 4 mittels eines Schiebers abzusperren.The flows into the hot blast tunnel 1 of a blast furnace system Hot wind in the direction indicated by the arrow. A hot body 2 is located in the inner wall of the hot blast channel 1 made of ceramic, εchi genuinely thermally conductive material arranged in such a way that it partially protrudes into the hot wind stream. Opposite it is an opening in the wall of the hot blast channel 1 3 attached, in which a sighting tube 4 for the pyrometer 5 is attached. LIit the one with photoelectric The pyrometer 5 working with receivers is aimed at the surface 6 of the Itleßkörpers 2. The surface 6 is light inclined against the direction of flow, as a result of which it is achieved that this surface increases the wind temperature particularly quickly accepts. In order to be able to remove or replace the pyrometer 5 without interrupting operation, there is the possibility of removing the visor tube 4 by means of a slide shut off.
