Vibratory flow burner for gaseous fuels - has cylinder in fuel and air inlet, to vary rotation of fuel and gas flows

摘要

A vibratory flow burner for use with gaseous type fuels having a central combustion gas input pipe and a coaxial air feed system has the vibration or turbulence flow device constructed from an inset cylinder (3, 9) mounted in the air/fuel gas input (1, 4) in a coaxial manner. - The device is open towards the combustion chamber, and has a window (6) parallel to the burner long axis in the region of the fuel/air inlet (2, 8). The cylinder (9) produces a variation in the direction of rotation of the fuel gas flow in the fuel gas input pipe (4).
