VERTICAL LIQUID OIL BOILER Russian patent published in 2023 - IPC F22B7/00 

FIELD: water heating and hot water systems.

SUBSTANCE: vertical hot water liquid fuel boiler, comprising a body, a heat exchanger of mains water, steam generators of superheated water vapor, steam-oil burners, where the heat exchanger of network water consists of upper and lower manifolds connected to each other by a flat tube bundle twisted in a spiral with a pitch sufficient for the passage of hot gases. Along the periphery of the heat exchanger there is a pipe wound along a cylindrical trajectory and acting as an outer wall, where the mains water enters the upper coil, and the lower coil enters the lower manifold, then the water passes through a flat bundle of spiral pipes upwards, ends up in the upper manifold, and from it goes out through the pipe to the consumer. In addition, the boiler comprises a vortex burner with a vertical axis, top and bottom covers, where a hole is made in the top cover for the exit of combustion products, and a hole is made in the bottom cover for a direct-flow steam-oil device that performs starting and acts as backlight, and the bottom cover has holes for air pipes.

EFFECT: compact hot water boiler.
