Abstract:
1. A method of warming up a fuel evaporator, the fuel evaporator comprising: an evaporation chamber equipped with a first injection device for injecting raw fuel liquid onto a heat source, and vaporizing the raw fuel liquid on the heat source; a catalyst combustor having a combustion catalyst, and introducing catalytically burned combustion gas into the heat source of said evaporation chamber; a second injection device for supplying fuel to said catalyst combustor; a combustion gas transferring device equipped with a fuel injection portion and a combustion catalyst, and the fuel injection portion injecting fuel onto the combustion catalyst to generate a catalytically burned gas, which is then transferred to the catalyst combustor; a first temperature measurement device for measuring a temperature of said catalyst combustor; and a second temperature measurement device for measuring a temperature of said evaporation chamber, wherein the method comprising the steps of: transferring the combustion gas with the combustion gas transferring device; stopping the combustion gas transferring device in accordance with a temperature of said catalyst combustor measured by the first temperature measurement device, and transferring fuel to said catalyst combustor with the second injection device; and injecting the raw fuel liquid from the first injection device in accordance with a temperature of said evaporation chamber measured by the second temperature measurement device so as to vaporize the raw fuel liquid within the evaporation chamber.
