| 摘要 |
A fuel evaporator (1) includes an evaporation chamber (11) to prepare a fuel gas FG by evaporating a liquid fuel FL with heat, a fuel injector (40) to supply a liquid fuel to the evaporation chamber, a plurality of heating medium tubes (12) to lead a combustion gas HG through said evaporation chamber, a superheating part (11U) to heat a fuel gas FG evaporated in said evaporation chamber by means of the combustion gas HG, an exhaust duct (22) to exhaust the fuel gas FG, and a fuel injection tube (41). The fuel injection tube is provided with a plurality of injection holes (42), said fuel injection tube being extended into said evaporation chamber and said fuel injection tube is provided crossing at right angle with respect to a heating medium tube. Injection property of the fuel injection tube in said evaporation chamber is greatly improved. The liquid fuel is evaporated effectively and rapidly.
