れにより黒煙を発生するという問題点があった。However, in such a conventional example, in order to prevent the oil in the oil tank from leaking from the tip of the nozzle by the head during the stop of the pump, the oil return pipe must be provided in the middle of the oil return pipe. An oil solenoid valve is provided in the tank, and the solenoid valve is closed during stoppage to prevent oil from flowing back from the oil return path of the return nozzle, and a first electromagnetic pump (hereinafter referred to as "low pressure pump"). Also, a valve for shutting off the oil suction side and the oil discharge side of the pump when the pump is stopped is provided inside the second electromagnetic pump (hereinafter, referred to as “high pressure pump”). The oil in the oil supply pipe connecting the oil discharge side of the high pressure pump and the oil suction side of the high pressure pump and the oil in the oil return pipe from the outlet of the oil solenoid valve connected to the oil supply pipe are closed, When the temperature of the pipe rises, the hydraulic pressure in the pipe also becomes abnormal. Elevated, thereby spraying the oil amount significantly above a predetermined spray amount at the next burner ignition, thereby disadvantageously generating black smoke.
