FUEL OIL OPERATING MOBILE HEATING DEVICE Russian patent published in 2016 - IPC F23D5/06 F23D11/44 F23D3/40 

FIELD: power industry.

SUBSTANCE: fuel oil operating mobile heating device contains a combustion chamber (2), that has input (3) for combustion air, at that the combustion chamber (2) has expanding section (20) abutting to the input (3) for combustion air, the expanding section cross-section increases with increasing of distance from input (3) for combustion air, and in it during operation the combustion air reacts with fuel with combustion crating flame; fuel supply located such, that fuel is supplied to the expanding section (20); and air directing device (6), intended for the combustion air directing from the flowing in circumferential direction flow component to the expanding section(20) such, that in the expanding section (20) the axial recirculation zone is created, in it gases flow opposite to main direction (H) of flow towards input (3) for combustion air, at that fuel supply has atomizer (15) for fuel injection at input (3) for combustion air.

EFFECT: invention allows improvement of the operating reliability of the heating device.
