Description

Gemischregler für industrielle Gasfeuerungen, bei welchen mehr als ein Heizgas zur Verbrennung gelangt. Bei Gasfeuerungen ist es erforderlich, die Verbrennungsluftmenge in einem bestimmten Verhältnis zur Gasmenge zuzuführen: Gewöhnlich werden die Gas- und Luftmengen, mit Hilfe von Staurändern, Venturirohren o. ä. gemessen und die Differenzdrucke durch Veränderung der Luftmenge in einem bestimmter. Verhältnis zueinander eingeregelt.Mixture regulator for industrial gas firing, where more than a heating gas is burned. With gas firing it is necessary to have the To supply the amount of combustion air in a certain ratio to the amount of gas: Usually the gas and air quantities are measured with the help of baffles, venturi tubes or the like and the differential pressures by changing the amount of air in a certain. relationship adjusted to each other.

In Abb. r stellt z den Brenner der Fewe# ru@ng r, 3 die Gasleitung, 4 die, Luftleitung dar. In Gase- und Luftleitung befinden. sich die Stauränder 5 -und 6: -I);ie Differenzdrucke werden abgelesen an den Meßinstrunienten 7 und B. Bei Ändenmgen in der Gaszufulhr verändert sich dez Däffenenzdmck bei 7 in gleichem Sinne. Die Eimmegelumg der Luftmenge geschieht düxch Verstellung einer Drosselvorrichtung 9, und zwar so lange, bis die Differenzdrucke 7 und 8 in dem geforderten Verhältnis zueinander stehen. Die Regelung geschieht von Hand bei Beobachtung der Anzeige der Meßinstrumente oder durch einen mechanischen Regler beliebiger Art i o, dessen Steuerwerk i i von den Differenzdrucken 7 und 8 an den. Staurändern, 5 und 6 beeinflußt wird.In Fig. R, z represents the burner of Fewe # ru @ ng r, 3 represents the gas line, 4 represents the air line. Located in the gas and air line. the pressure rims 5 and 6: -I); the differential pressures are read off on the measuring instruments 7 and B. If there are changes in the gas supply, the difference in pressure at 7 changes in the same way. The amount of air is adjusted by adjusting a throttle device 9 until the differential pressures 7 and 8 are in the required ratio to one another. The regulation is done by hand while observing the display of the measuring instruments or by a mechanical controller of any type io, whose control unit i i of the differential pressures 7 and 8 to the. Jam margins, 5 and 6 is affected.

Dieses allgemein gebräuchliche Verfahren ist anwendbar, solange die Gasfev,erung mit einem Heizgas von gleichbleibendem Heizwert beliefert wird, wie überhaupt nur bei solchen Feuerungen, die mit nur einem einzigen Gas arbeiten. Gelangen mehrere Gase zur Verbrennung, so. ist es gebräuchlich, die Gase vor ihrem Eintritt in den Ofen zu mischen (Abb. i, Leitung Gas i, Gas 2). Dann ist es möglich, das eingangs beschriebene Regelverfahren anzuwenden, jedoch nur dann, wenn das Mengenverhältnis der beiden Gase und damit der Heizwert und davon abhängig der Luftbedarf des Mischgases derselbe bleibt. Soll das Mengenverhältnis geändert werden, wie es in solchen Betrieben häufig &r Fall ist, in denen die einzelnen Gase (z. B. Hoc'hofengas und Koksofiengas) nur als überschußgase zur Verfügung stehen, so ist es erforderlich, bei jeder Änderung des Mengenverhältnisses der Gase auf rechnerischem Wege Heizwert und Luftbedarf des Mischte gares zu bestimmen und dementsprechend die Regelung vorzunehmen. Eine solche Arbeitsweise ist umständlich und völlig unbrauchbar, sobald mehr als zwei Gase zur Verbrennung gelangen, wie es. häufig in Martinwerken der Fall ist.This commonly used procedure is applicable as long as the Gasfev, erung is supplied with a heating gas of constant calorific value, such as only in the case of furnaces that work with just one single gas. Reach several gases for combustion, so. it is common practice to remove the gases before they enter to mix in the oven (Fig. i, pipe gas i, gas 2). Then it is possible that to use the control method described at the beginning, but only if the quantitative ratio of the two gases and thus the calorific value and, depending on this, the air requirement of the mixed gas remains the same. Should the quantity ratio be changed, as it is in such establishments is often the case in which the individual gases (e.g. Hoc'hofengas and Koksofiengas) are only available as excess gases, so it is necessary with every change the quantitative ratio of the gases calculated by means of calorific value and air requirement of the mixed cooking and to adjust accordingly. One Such a way of working is cumbersome and completely useless as soon as more than two Gases get burned like it. is often the case in Martinwerke.

Es- wird deshalb vorgeschlagen, die Entnahme der Differenzdrucke nicht in der Mischgasleitung, sondern in den einzelnen Leitungen vorzunehmen und gleichzeitig die Windmengen durch ebenso viele Leitungen zuzuführen, wie' verschiedene Heizgase angewandt werden. Es erhält also jede Gasleitung ihre bestimmte Windleitung, wobei: dann die erwähnten Schwierigkeiten fortfa71en und für jedes Gas allein das eingangs beschriebene Verfahren Anwendung finden kann. Das neue Verfahren ist in Abb. 2 dargestellt.It is therefore suggested not to take the differential pressures in the mixed gas line, but in the individual lines and at the same time to feed the wind through as many lines as' different heating gases can be applied. So every gas pipe receives its specific wind pipe, whereby: then continue the difficulties mentioned, and for each gas only the one at the beginning described procedure can be used. The new process is shown in Fig. 2.

Nach den Differenzdrucken i i und 12 wird mit der Drosselvorrichtung 15 die Luftmenge für das Gas i und in gleicher Weise nach den Differenzdrucken 13 und i q. mit der Drosselvorrichtung 16 die Luftmenge für das Gas 2 eingeregelt. Auch hier kann die Regelung durch Hand oder mechanisch erfolgen.After the differential pressures i i and 12, the throttle device is used 15 the amount of air for the gas i and in the same way according to the differential pressures 13 and i q. the amount of air for gas 2 is regulated with the throttle device 16. Here, too, regulation can be carried out manually or mechanically.
