摘要： PROBLEM TO BE SOLVED: To provide a liquid spray burner and residual fuel removal method of the same having a low environmental load and capable of collecting residual liquid fuel. SOLUTION: A fuel removal line 37 connected to a fuel supply line 24 and a fuel removal valve 38 provided in the fuel removal line 37 are provided. By supplying gas to a tip side of a fuel nozzle 21 by a fan 27 during stop of combustion operation, pressure on the tip side of the fuel nozzle 21 is intensified, and the fuel removal valve 38 is opened. Thus, due to a difference between the pressure on the tip side of the fuel nozzle 21 and the pressure on a fuel discharge side of the fuel removal line 37, residual liquid fuel 39 inside the fuel nozzle 21 is removed from inside of the fuel nozzle 21 and discharged via the fuel removal line 37 and the fuel removal valve 38 (first fuel removal). Also after the first fuel removal, by supplying gas to the tip side of the fuel nozzle 21 by the fan 27, fuel vaporized inside the fuel nozzle 21 is sucked out from a fuel outflow hole 31 (second fuel removal).
