BURNER Russian patent published in 2023 - IPC F23C1/10 F23L7/00 

FIELD: power engineering.

SUBSTANCE: used for fuel combustion in power plants of low power, in swirl burners with steam gasification of combustion products. The burner device contains a spray-ignition unit and a steam gasification chamber connected by means of a cover, where the spray-ignition unit consists of a cylindrical body and a base in which a steam spray nozzle, a fuel supply pipe and a spark plug are mounted, and the steam gasification chamber consists of a cylindrical body, in the walls of which there is a heat exchanger for obtaining superheated water vapor, on one side of which there is a cover with swirl steam nozzles placed in it, and on the other side a nozzle for the exit of hot gases. At the base of the spray-ignition unit, such a number of spray nozzles is installed that is necessary to obtain the required power of the burner device, both for supplying liquid fuel in the form of a steam-oil aerosol, and for supplying pulverized-coal fuel in the form of an air mixture, and on the opposite side of the base of the spray-ignition block on the cylindrical body there is a collector for compressed air and an annular diffuser connected to the collector by an annular channel. In this case, the spray nozzles are installed in such a way that their axes are directed at an angle to the central axis of the device and intersect in the area of action of the steam swirl nozzles of the steam gasification chamber, and the opening angle of the air mixture flow is such that the jet diameter in the annular diffuser zone is greater than the inner diameter of the annular diffuser.

EFFECT: creating a burner device that is self-cleaning directly in the process of operation when burning used engine oil from deposits on internal hot working surfaces of additives contained in engine oil.
