FUEL COMBUSTION DEVICE Russian patent published in 2015 - IPC F23R3/34 

FIELD: heating.

SUBSTANCE: invention relates to fuel combustion applications and can be applicable in propulsion jet engines, in gas-turbine, furnace and heat power units, in units for processing and utilisation of household and industrial wastes. The fuel combustion device comprises the combustion chamber containing the conic flame tube forming the channel for supply of main air, the device for supply of main fuel into the housing. The device for supply of the main fuel is adjoined by the combustion chamber head in the form of sphere with the radius equal to the radius of the flame tube. The housing of the combustion chamber contains a cover with internal surface in the form of "toroid". The end face of a wall of the flame tube is made rounded and together with the internal surface in the form of "toroid" forms the channel with the cross section equal to the through passage equal to the cross section of the channel through passage formed by the outer diameter of the flame tube and internal diameter of the device housing. The end face of the flame tube is embedded into the cover to the length, equal to that of minimum two distances between the housing and the flame tube. On the opposite side of the flame tube the combustion chamber head fitted with the starting fuel nozzle and the spark plug is located.

EFFECT: invention is aimed at simplification of design and technology of assembly, improvement of operating reliability.
