A device for flaring combustible gases, having an adjustable opening cross-section, and three tubes arranged about a common longitudinal axis. The tubes are arranged at least in some sections in a common cross-sectional plane an inner tube is designed as a gas introduction tube and has an opening that ends at the top in the vertical direction a diaphragm that can be adjusted in the cross section, through which the gas stream can be closed or regulated and which is fitted with an automatable mechanism for adjusting the opening cross-section. The device typically contains also at least one air guiding plate, feed devices for an inert gas and an ignition mechanism, thereby ensuring a high reliability for flaring the gas and a low emission of nitrogen oxides and soot. A method for operating the device which is suitable for flaring crude gases which are to be combusted is also disclosed.
