Abstract:
1. A gas supply apparatus equipped with a vaporizer, the gas supply apparatus comprising: (a) a liquid receiving tank; (b) a vaporizer disposed to vaporize liquid pressure-fed from the liquid receiving tank to the vaporizer; (c) a high-temperature type pressure type flow rate control device disposed to adjust a flow rate of outflow gas from the vaporizer, wherein the high-temperature type pressure type flow rate control device comprises a control valve, a driving section, an orifice, an arithmetic control device, a pressure detector and a temperature detector; (d) a plurality of heating devices disposed to heat the vaporizer, the high-temperature type pressure type flow rate control device, and portions of pipe passages connected to the vaporizer and to the high-temperature type pressure type flow rate control device; (e) a liquid supply control device disposed to adjust an amount of liquid to be pressure-fed to the vaporizer from the liquid receiving tank so that gas pressure on an upstream side of the high-temperature type pressure type flow rate control device reaches a predetermined setting pressure or higher; and (f) a temperature control device disposed to adjust a heating temperature of the vaporizer so that the gas pressure on the upstream side of the high-temperature type pressure type flow rate control device reaches the predetermined setting pressure or higher.
