Burner for fuel oil combustion comprises a chamber with nozzles mounted in several planes normally to the axis of the air supply duct. Nozzles are made with diameters with the ratio values of D:D:Din the direction of flow of fuel oil 1,0:0,3-0,5:0,6-1,5. Air supply to channel is through damper with holes arranged in the form of slots in concentric circles the sides of which in direction of air supply form angles α=(30-60)°, at input, and α=(90-120)° at the output. The burner further comprises a chamber connected with the first chamber through a throat. In the cross section of the throat ejection openings are formed, with angles of inclination to the burner channel axis in the direction of flame flow β=(35-65)°.
