PURPOSE: To supply gas to a use place at high delivery pressure by providing liquid tanks, gas tanks connected to the liquid tanks by conduits, a liquid vaporizing means, and a means for feeding gas from the vaporizing means into the use place. CONSTITUTION: A high pressure gas supply system comprises liquid tanks 10, 11, gas tanks 6-9, a vaporizer 21 and a gas force-feeding means. In order to feed gas into a place 1 at high delivery pressure, the liquid supply tanks 10, 11 are maintained to lower pressure than the delivery pressure, and gas supply is maintained to pressure equal to the delivery pressure. Gas is fed from the gas supply tanks 6-9 to the liquid supply tanks 10, 11, and the pressure of the liquid supply tanks 10, 11 are raised to higher pressure than the delivery pressure. Liquid is vaporized into produced gas from the liquid supply tanks 10, 11 with the pressure equal to the delivery pressure and fed to the use place 1 of this gas. As a result, gas can be stably supplied into the gas use place 1 at high delivery pressure. |
