Abstract

Настоящее изобретение относится к пламенной горелке, снабженной расположенным в головке соплом (10), в которой дополнительно к кольцеобразно расположенным газоподающим каналам (11) сопло снабжено центральным газоподающим каналом (12), имеющим секцию в виде сопла Лаваля и стабилизирующую секцию, имеющую постоянный диаметр, соединенную с ней. С целью газопламенной обработки газообразному кислороду, подаваемому через центральное сопло пламенной горелки, придают колебания таким образом, чтобы обеспечивалось истечение пульсирующего потока кислорода из выходного отверстия сопла со скоростью звука или сверхзвуковой скоростью.The present invention relates to a combustion burner equipped with a nozzle (10) located in the head, in which, in addition to the annular gas supply channels (11), the nozzle is provided with a central gas supply channel (12) having a section in the form of a Laval nozzle and a stabilizing section having a constant diameter, connected to it. For the purpose of flame treatment, the oxygen gas supplied through the central nozzle of the flame burner is oscillated so that a pulsating flow of oxygen is provided from the nozzle outlet at the speed of sound or supersonic speed.
