TURBULENT NOZZLE Russian patent published in 2023 - IPC F23D11/44 

FIELD: energy.

SUBSTANCE: present invention relates to energy and can be used in oil and gas-oil burners of heat generating installations. The turbulent nozzle contains a cylindrical body, the bottom of which is made in the form of a diffuser and is mounted from the outside on the outer side of the end of the fuel supply tube, the spray head is equipped with outlet holes located along its periphery, and a central hole closed by a heating sleeve facing the combustion chamber and located in inside, in the center of the heating sleeve, there is an exhaust pipe connected by its left end to the fuel supply pipe and closed from the right end by a perforated valve pressed by an elastic element that rests on the inner surface of the end cover of the heating sleeve, in which the exhaust pipe is located in such a way that that between them there is an annular circulation channel connected to the cavity of the cylindrical body, and the nozzle itself is placed coaxially in the burner body, inside which the primary and secondary air channels are arranged concentrically and which is placed, in turn, in a firebox mbrazuru. An annular turbulator is mounted on the end of the nozzle body, consisting of a ring, support heels attached to its outer end, and guide vanes also attached to the outer end of the ring and support heels opposite each outlet with an inclination angle α relative to the tangent at the point of connection of the blade with the outer ring edge.

EFFECT: invention allows to reduce fuel consumption and pollution of the surrounding atmosphere by its unburned residues.
