Drawing of a Thiele tube with red arrows showing convection current A photograph of a Thiele tube. The oil level is a little low now to compensate for expansion when heating commences. The Thiele tube, named after the German chemist Johannes Thiele, is a laboratory glassware designed to contain and heat an oil bath.
The first series of German man-portable flamethrower was called the Kleinflammenwerfer ('small flamethrower') or "Kleif". Fuel oil was stored in a large vertical, cylindrical backpack container. High-pressure propellant was typically stored in another, smaller container within the fuel tank or attached externally depending on model.
Their flame is limited to approximately 5 centimeters (two inches) in height, with a comparatively lower temperature than the gas flame of the Bunsen burner. [ 2 ] [ 3 ] While they do not produce flames as hot as other types of burners, they are sufficiently hot for performing some chemistries, standard microbiology laboratory procedures, and ...
Dragon's breath (sustained vertical breath without a torch in front of the flame) Fire art is a piece of art that uses active flames as an essential part of the piece. The piece may either use flame effects as part of a sculpture, or be a choreographed performance of fire effects as the piece burns; the latter being almost a type of performance art.
An incandescent gas mantle, gas mantle or Welsbach mantle is a device for generating incandescent bright white light when heated by a flame. The name refers to its original heat source in gas lights which illuminated the streets of Europe and North America in the late 19th century. Mantle refers to the
A glow plug engine, or glow engine, is a type of small internal combustion engine [1] typically used in model aircraft, model cars and similar applications. The ignition is accomplished by a combination of heating from compression, heating from a glow plug and the catalytic effect of the platinum within the glow plug on the methanol within the ...

The grid separates the flame into an array of smaller flames with a common external envelope, and also prevents flashback to the bottom of the tube, which is a risk at high air-to-fuel ratios and limits the maximum rate of air intake in a conventional Bunsen burner. Flame temperatures of up to 1,100–1,200 °C (2,000–2,200 °F) are ...
