VORTEX BURNER Russian patent published in 2022 - IPC F23D14/02 

FIELD: thermal power engineering.

SUBSTANCE: invention relates to the field of thermal power engineering, in particular to burners for burning gaseous and liquid fuels in them. The vortex burner device contains an external cylindrical fuel combustion chamber, an internal cylindrical outlet chamber-nozzle, which is installed inside the outer cylindrical combustion chamber, a tangential fuel supply pipe and a tangential air supply pipe, a water jacket of the cooling system of the outlet chamber-nozzle, a steam pipeline with a steam nozzle. The inner cylindrical outlet chamber-nozzle is located inside the outer combustion chamber along its entire length and is equipped with longitudinal tangential holes or two tangential rectangular windows, oppositely installed relative to the axis of the outlet chamber-nozzle for supplying flow inside with a window width equal to half the radius of the outlet chamber-nozzle, and adjustable length, and the water jacket, along with cooling the outlet chamber-nozzle, acts as a steam generator and a superheater and is connected via a steam pipeline to an external fuel combustion chamber.

EFFECT: efficient combustion of any, including non-design, liquid or gaseous fuels, ensuring low levels of NO_x and CO emissions.
