ARRANGEMENT FOR REDUCING ACOUSTIC VIBRATIONS IN COMBUSTION CHAMBER Russian patent published in 2004 - IPC

FIELD: devices provided with combustion chambers. SUBSTANCE: device incorporating combustion chamber has combustion chamber and set of burners; each burner is provided with outlet communicating with combustion chamber and has components for feeding oxygen-containing gas flow to burner, components for feeding fuel to burner and to space running to combustion chamber in longitudinal direction that incorporates provision for mixing up fuel and oxygen-containing gas being supplied. Each burner is equally capable of passing large amount of oxygen-containing gas to combustion chamber. Each burner is characterized in at least one parameter including characteristic length (a) of space in longitudinal direction and in that characteristic length (a) of at least one of mentioned burners is chosen so that it deviates from respective length (a) of other burner in mentioned set in such way that effect of vibrations set up in the course of operation of device incorporating combustion chamber reduces. EFFECT: reduced impact of acoustic vibrations without causing emission of nitrogen oxides and the like. 19 cl, 5 dwg
