PROBLEM TO BE SOLVED: To provide a fuel evaporator which can effectively and speedily evaporate liquid ray fuel by improving jetting characteristics of liquid fuel in of an evaporation chamber. SOLUTION: In a fuel evaporator 1 comprising an evaporation chamber 11 for evaporating liquid fuel FL by heat so as to make FL into fuel gas FG, fuel jetting means 40 for supplying liquid fuel FL to the evaporation chamber 11, a plurality of heating medium tubes 12 which pass through the evaporation chamber 11 and through which combustion gas HG passes, an overheating portion 11U for overheating fuel gas FG evaporated in the evaporation chamber 11 with the fuel gas HG, and an exhaust opening 22 for exhausting fuel gas FG, a fuel jetting tube 41 in which a plurality of jetting holes 42 are perforated is arranged in the fuel jetting means 40 so as to extend to an interior of the evaporation room 11 and lie at right angles to the heating medium tubes 12. |
