BURNER DEVICE Russian patent published in 2022 - IPC F23C99/00 

FIELD: power industry.

SUBSTANCE: invention relates to the field of energy and can be used in heat generating plants for the implementation of controlled steady pulsating combustion. The burner device contains a housing tangentially connected to the source of the blast air, along the axis of which a combustion stabilizer is installed at the outlet, made in the form of a conical jet-stabilizer grate with a cone opening angle of 60-90°, and a fuel chamber, hemisphere-shaped and rigidly bonded to the liquid fuel supply pipeline and with a combustion stabilizer, on the spherical wall of which at least three fuel injectors are installed placed evenly along the circumferential coordinate and at an angle to the central axis of the burner device housing, moreover, a narrowing device in the form of a Laval nozzle connected by a recirculation pipeline to the fuel chamber is installed on the liquid fuel supply pipeline in front of the fuel chamber. The outlet part of the burner device housing is made in the form of a diffuser nozzle with a taper of 0.33-0.1, inside which a conical divergent nozzle is installed, rigidly fastened to the diffuser nozzle and forming together with it a wall channel of at least 15-20 mm and 8-10 mm in size, respectively, at the inlet and outlet, to separate the common flow of blasting air supplied tangentially to the primary and secondary and cooling by the secondary flow of blasting air of the diffusor and conical divergent nozzles, and the supply of this air flow to the peripheral region of the liquid fuel combustion zone, in addition, in the cylindrical part of the burner device housing, a hollow cylinder rigidly attached to the housing with at least three radial plates located inside the cylinder at an angle of 60-80° to the axis of the burner device in the direction of movement of the tangentially swirled air flow is installed in front of the diffuser nozzle, by means of which a cylindrical sleeve is installed for the longitudinal movement of the liquid fuel supply pipeline together with a rigidly fastened fuel chamber and a combustion stabilizer, the maximum diameter of the radial section of which does not exceed the minimum diameter of the conical divergent nozzle, and the cylindrical sleeve is installed in the end part of the burner housing.

EFFECT: increase in the efficiency and reliability of the burner device.
