About the Danger of Vibration Combustion in Gas Explosions in the Room

Abstract

Abstract In recent years, in experimental gas explosions in open volumes, such a phenomenon as vibration combustion has been recorded or, as they sometimes say, flame-acoustic combustion, or simply combustion, but accompanied by acoustic gas oscillations. Generally speaking, this type of combustion was known for a long time in the 19th century, from the time of Higgins and Rijke, and acquired the poetic name “singing flame”. However, at the onset of gas turbine and rocket engines, this phenomenon manifested itself in their combustion chambers and was designated as a whip, as it resulted in structural damage. But the vibration combustion is known not only for the destructive force, but also for the intensification of fuel combustion process in high-duty furnaces.
