STEAM-OIL BURNER DEVICE Russian patent published in 2025 - IPC F23L7/00 F23C99/00 

FIELD: heat engineering.

SUBSTANCE: burner device comprises a cylindrical housing in the form of a cup, a nozzle in the form of a cover with a hole in the centre, mounted at the end of the housing, a steam nozzle and a steam supply nozzle installed in the bottom of the housing, a fuel feed pipe; air supply holes made on the cylindrical housing near the bottom, branch pipes with a flame presence sensor and spark plugs mounted into the housing bottom. Device has an external housing, along the radius larger than the cylindrical housing, but less than it in height, where the cylindrical housing is mounted on the rear wall on the inner side, as well as, with some offset to it, air supercharging fan, which injects the combustion air from the environment with a small excess pressure both into the cylindrical housing, and to the external nozzle fixed to the external housing front wall on the outer side coaxially with the cylindrical housing, facing the combustion space, forming the external flame and guiding the combustion products into the boiler plant combustion space.

EFFECT: invention allows obtaining heat energy at combustion of liquid hydrocarbon fuels, including non-design ones, and their mixtures in a jet of superheated water steam under conditions of a closed combustion chamber of a boiler plant without using an external source of compressed air.
