Description

Предлагаема  горелка с знешнп смешением газов дл  газопламенногонапылени  тугоплачзких порошчос-бразных материалов с мундштуком защищенным от -ерегрева металлическим экра}шм, и центральным каналом дл  подачи напыл емого порошка отличаетс  от известных тем что дл  защиты мхндштука от перегрева порошковын канал в ней выполиен в виде сплощной металлической трубки с раструбом  вл ющимс  одновременно экраном, защищающим мундштук. Такое выполнение экрана обеспечивает интенсивное его охлаждение воздунгно-порощковой смесью и хорошую защиту мундштука от перегрева , что позвол ет повысить температуру пламени без вреда дл  горелки .The proposed burner with external mixing of gases for gas-flame evaporation of refractory powder materials with a mouthpiece protected from overheating of the metal screen} CM and a central channel for supplying the sprayed powder differs from the known one in that to protect the powder from the overheating, the channel for supplying the sprayed powder differs from a metal tube with a bell is at the same time a shield protecting the mouthpiece. Such an embodiment of the screen ensures its intensive cooling by the powder-powder mixture and good protection of the mouthpiece against overheating, which makes it possible to raise the flame temperature without harming the burner.

На чертеже показана горелка, общий :;;;д.The drawing shows the burner, common: ;;; d.

Она состоит из кольцевой распределительно камеры / с г.одвод щими трубками 2, центрального порошкового сопла 3 и теплоизол ционной прокладки 4. Сопло 3 изготовл етс  из теплопроводного метал та например меди, и имеет ребра воздущного охлалиенп  5. Камера 1 сообщаетс  с атмосферой кольцевой щелью 6 и р дом oTBepj:THH 7, расположенных по окружности большего диаметра, чем внешний диаметр Кольцевой шели 6.It consists of an annular distribution chamber (with g. Leading pipes 2), a central powder nozzle 3 and a heat insulating gasket 4. The nozzle 3 is made of heat conducting metal, such as copper, and has air cooling edges 5. Chamber 1 is connected with the atmosphere by an annular gap 6 and beside oTBepj: THH 7, located around a circumference of a larger diameter than the outer diameter of the annular shell 6.

Напыл емый материал вместе с транспортирующим его газом (ки-стороаом ) подаетс  в сопло 3 через канал S, который затем переходит в адффузор 9 и заканчиваетс  раструбом W. Горюча  смесь по трубкам подаетс  в камеру /, из которой она в виде компактиых струи выходит через кольцевую шель 6 и отверсти  7. Сечение кольцевой щели 6 и отверстий 7 выбираетс  таким, чтобы исключить проскок пламе;:;: в камеру 1 при зажигапии горючей смесп.The sprayed material, together with the gas transporting it (Ki-Storoom), is fed into the nozzle 3 through the channel S, which then passes into the ad- fuse unit 9 and ends with the socket W. The combustible mixture is fed through the tubes into the chamber /, from which it comes out as a compact jet through annular shell 6 and holes 7. The cross section of the annular slit 6 and holes 7 is chosen so as to exclude flame penetration;::: into chamber 1 when igniting a combustible mixture.
