BURNER HEAD OF BURNER DEVICE Russian patent published in 2018 - IPC F23D14/02 

FIELD: energy.

SUBSTANCE: invention relates to the field of energy, namely burners for burning liquid and gaseous fuels, and can be used in burners, used in fire-tube low power water boilers. In the method, the burner head of the burner device includes a housing, in which a cylindrical gas manifold with a central channel is coaxially installed, a central diffuser disk, an adjusting ring mounted on the inner surface of the body with the possibility of movement relative to the longitudinal axis of the burner head, wherein the housing is provided with a diffuser-confluent outlet nozzle; a cylindrical gas manifold is installed in the housing to form an annular channel for supplying peripheral airflow to the combustion zone; on the outer surface of the cylindrical gas manifold along the circumference there are axial blades installed at an angle of 30–40° to the longitudinal axis of the burner head; in the outlet part of the cylindrical gas manifold, groups of nozzle openings are circumferentially spaced, they are intended for supplying gaseous fuel to the peripheral air flow, wherein there is a bluff body behind each group of holes; in the central diffuser disk, a central hole, radial slotted slots and at least four groups of radially placed openings are provided with at least two holes in each group; the central diffuser disk is installed in the housing to form an annular gap between the diffuser portion of the outlet nozzle, whose value is regulated by the longitudinal movement of the adjusting ring.

EFFECT: technical result is an increase in the efficiency of the burner device, in particular efficiency, due to ensuring stable ignition of fuel in the operating range of boiler loads from 40 to 100 % of the rated power and complete burn-up of fuel in the volume of the fire tube of the boiler with a minimum incomplete combustion and an increase in the environmental friendliness of the burner by reducing the emission of nitrogen oxides during fuel combustion.
