Rotational flow long flame fuel oil burner system

The invention relates to a rotational flow long flame fuel oil burner system which comprises an inner container, an outer container, an oil pump and a fan. The inner container is located in the outer container, the front end of the inner container and the front end of the outer container are opened to form a fire spraying opening, and the front end of the outer container exceeds the front end of the inner container by a preset distance. An atomizing oil nozzle is installed on the inner wall of the rear end of the inner container, the oil pump is connected with the atomizing oil nozzle through an oil pipe, and an ignition needle for igniting and combusting fuel oil atomized by the atomizing oil nozzle is arranged at the position, corresponding to the atomizing oil nozzle, of the inner wall of the rear end of the inner container. The fan communicates with the interior of the outer container through an air pipe and sequentially provides multiple times of inlet air in the fuel oil combustion process. The device h
