Изобретение относитс к тепловой обработке металлов и может быть использовано дл подогрева газовой смеси пропано-кислородной горелки.The invention relates to the heat treatment of metals and can be used to heat a gas mixture of a propane-oxygen burner.
Известные способы, которыми производ т подогрев потока горючей смеси, не обеспечивают эффективный подогрев.The known methods by which the flow of a combustible mixture is heated do not provide effective heating.
С целью устранени указанного недостатка по предложенному способу подогрев потока осуществл ют дополнительным кольцевым потоком горючей смеси, подаваемым под углом к основному.In order to eliminate this drawback according to the proposed method, the stream is heated by an additional annular stream of the combustible mixture supplied at an angle to the main stream.
При осуществлении способа дополнительный подогревающий факел направл ют под углом к основному потоку газовой смеси, смешива его с газовой смесью по всему периметру струи. Дополнительный факел обжимает основной поток газовой смеси, подогревает его, способствует концентрации дра пламени и защищает от попадани в него азота воздуха , так как продукты сгорани подогревающего факела образуют вокруг защитную оболочку . Кроме подогрева дополнительный факел одновременно осуществл ет перемешивание основного потока газовой смеси, что активирует процесс горени . Этим достигаетс нагрев газовой смеси до более высокой температуры (800°С), а, следовательно, ее раннее воспламенение и более полное сгорание вблизи дра пламени.In the process, the additional heating torch is angled to the main flow of the gas mixture, mixing it with the gas mixture around the entire perimeter of the jet. An additional torch compresses the main stream of the gas mixture, heats it, promotes the concentration of the flame core and protects nitrogen from the air because the combustion products of the heating torch form a protective sheath around it. In addition to heating, an additional flame simultaneously mixes the main stream of the gas mixture, which activates the combustion process. This achieves heating of the gas mixture to a higher temperature (800 ° C), and, consequently, its early ignition and more complete combustion near the flame core.
