NOVELTY - A vaporization apparatus consists of a vaporization portion (3), a water supply portion (P1), a fuel supply portion (P2), a control portion (6), a temperature detecting portion, and a flow rate detecting portion (F1). The vaporization portion has a heater which heats and vaporizes liquid fuel and water. The control portion is equipped with a unit for starting supply operation of liquid fuel when the detected flow rate of water lies in preset range with respect to a target flow rate, after starting supply operation of water.    USE - Vaporization apparatus is used for vaporizing liquid fuel and water in electric-power generators (claimed) used in portable apparatuses, such as notebook personal computers and mobile telephones.    ADVANTAGE - The vaporization apparatus suppresses generation of pulsation and enables stable electric-power generation.    DETAILED DESCRIPTION - A vaporization apparatus consists of a vaporization portion (3), a water supply portion (P1), a fuel supply portion (P2), a control portion (6), a temperature detecting portion, and a flow rate detecting portion (F1). The vaporization portion has a heater which heats and vaporizes liquid fuel supplied by the fuel supply portion and water supplied by the water supply portion. The control portion controls operation of water supply portion and fuel supply portion. The temperature detecting portion detects the temperature of heating portion. The flow rate detecting portion detects the flow rate of water supplied to the vaporization portion. The control portion is equipped with a unit for starting supply operation of liquid fuel when the detected flow rate of water lies in preset range with respect to a target flow rate, after starting supply operation of water. An INDEPENDENT CLAIM is included for drive control method of vaporization apparatus.    DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of an electric-power generator.
