Abstract:
1. A raw fuel vaporizing apparatus comprising: a vaporizer for vaporizing liquid raw fuel; a raw fuel introducing device for introducing the liquid raw fuel into the vaporizer; a catalyst combustor into which fuel and air are supplied for catalytic combustion, the catalyst combustor generating heat in the presence of a catalyst and supplying the resulting heat to the vaporizer so as to vaporize the liquid raw fuel; a fuel introducing device for introducing the fuel into the catalyst, combustor; an air introducing device for introducing the amount of the air suitable for catalytic combustion into the catalyst combustor; a heat transferring gas introducing device introducing heat transferring gas into the catalyst combustor so as to transfer heat retained by the catalyst combustor to the vaporizer; and a controller increasing the amount of the heat transferring gas through the heat transferring gas introducing device when a demand amount of vapor to be generated in the vaporizer is increased.
