Description

Verfahren zum Betreiben von Gas-Luft-Sauerstoff-Brennern Es sind bereits Gas-Luft-Sauerstoff-Brenner bekanntgeworden, bei welchen die Brennstoffe innerhalb des Brenners gemischt werden, ferner noch sogenannte Getrenntbrenner, bei welchen sich das Gas und das Luft-Sauerstoff-Gemisch erst beim Austritt aus der Brennerdüse vereinigte. Mit diesem Brenner waren aber nur Flammen von rundem Querschnitt und geringem Durchmessererreichbar.Process for operating gas-air-oxygen burners There are already Gas-air-oxygen burners have become known, in which the fuels are inside of the burner, furthermore so-called separate burners, in which the gas and the air-oxygen mixture only change when they exit the burner nozzle united. With this burner, however, there were only flames with a round cross-section and small diameter achievable.

Gegenstand vorliegender Erfindung betrifft eine Verbesserung dieser bekannten Brenner, die darin besteht, daß durch den aus einer Düse unter Druck ausströmenden Sauerstoff die Luft und hierauf durch das Luft-Sauerstoff-Gemisch mittels einer zweiten Düse das Brenngas angesaugt wird.The present invention relates to an improvement in this known burner, which consists in that flowing out of a nozzle under pressure through the Oxygen the air and then through the air-oxygen mixture by means of a second nozzle the fuel gas is sucked in.

Das zwangläufige Mischverfahren von Luft und Sauerstoff ist ebenso für Getrenntbrenner von großer Bedeutung, weil auch dabei gleichmäßige, ruhig brennende und wesentlich größere Flammen zu erzielen sind als bei der bisherigen primitiven Methode, einfach Sauerstoff in die Luftleitung einzuführen. Eine gründliche Mischung des Sauerstoffs mit der Luft war dabei gar nicht möglich, und wenn man reichlich Sauerstoff gegeben hat, wurde die Luft schließlich überhaupt zurückgedrängt, und der Sauerstoff drang darauf in die Luftleitung ein. Nach dem neuen Verfahren ist in allen Fällen weder ein Zurücktreten der Luft noch des Gases durch den ' Sauerstoff möglich, weil der Sauerstoff bzw. das Luft-Sauerstoff-Gemisch durch eine Injektordüse geschickt werden, wodurch Luft und Gas zwar angesaugt, aber nicht zurückgedrängt werden können.The inevitable mixing process of air and oxygen is also This is of great importance for separate burners because they also burn evenly and calmly and much larger flames can be achieved than with the previous primitive Method of simply introducing oxygen into the air line. A thorough mix The oxygen with the air was not possible, and if one was plentiful When there was oxygen, the air was eventually pushed back at all, and the oxygen then penetrated the air duct. According to the new procedure is in all cases neither the air nor the gas withdrawing from the oxygen possible because the oxygen or the air-oxygen mixture through an injector nozzle sent, whereby air and gas are sucked in, but not pushed back can be.

Der Sauerstoff strömt dabei entsprechend reduziertem Druck durch die Sauerstoffdüse und reißt dabei die Luft, welche in beliebiger Weise zugeführt werden kann, in einen Stauraum. An diesen Stauraum ist ein Rohr angeschlossen, welches eine Düse aufweist, wo= bei der aus dieser Düse austretende Sauerstoffluftstrahl irgendein durch ein Rohr o. dgl. eintretendes, brennbares Gas mitreißt, welches sich mit dem Sauerstoffluftstrahl vermischt, wodurch ein sehr gutes Gemenge zustande kommt, welches unter großer Wärmeentwicklung restlos verbrennt. Selbstverständlich kann die Menge der drei Medien durch entsprechende Hähne o. dg1. geregelt werden, wodurch das Sauerstoff-Luft-Gas-Gemisch je nach dem gewünschten Zweck beliebig geändert werden kann.The oxygen flows through the correspondingly reduced pressure Oxygen nozzle and tears the air, which are supplied in any way can, in a storage space. A pipe is connected to this storage space, which has a nozzle where the oxygen air jet emerging from this nozzle entrains any combustible gas entering through a pipe or the like, which mixes with the oxygen air jet, resulting in a very good mixture comes, which burns completely with great heat development. Of course the amount of the three media can be adjusted using the appropriate taps or dg1. be managed, whereby the oxygen-air-gas mixture is arbitrarily changed depending on the desired purpose can be.
