A vaporizer (10) including an inlet (12) for liquid and an outlet (14) for gas, a gas valve (16) controlling gas flow to the outlet (14) of the vaporizer (10), and means (20) for heating liquid flowing between the liquid inlet (12) and the gas valve (16). The vaporizer (10) also includes means (18) for increasing a heat transfer rate of the liquid flowing between the liquid inlet and the gas valve, and for causing a pressure drop in the liquid so that a pressure of the liquid drops below a vapor transition pressure of the liquid upon reaching the gas valve. The pressure drop occurs under isothermal conditions, and the liquid is vaporized on demand only when the valve (16) is opened. The means (18) for increasing a heat transfer rate and for causing a pressure drop can be a plug of porous media. |
