Patent ID: 8544828

Claim:
A liquid material vaporization apparatus comprising: a gas-liquid mixing section in which a liquid material and a carrier gas are mixed, a liquid material introduction path to introduce the liquid material into the gas-liquid mixing section, a carrier gas introduction path to introduce the carrier gas into the gas-liquid mixing section, a vaporization nozzle section that is communicated with the gas-liquid mixing section to subject a mixture of the liquid material and the carrier gas to flash boiling, a mixed gas derivation path that is communicated with the vaporization nozzle section to derive mixed gas vaporized by the vaporization nozzle section, and a bypass path through which the carrier gas introduction path is communicated with the mixed gas derivation path on a downstream side of the vaporization nozzle section to flow the carrier gas from the carrier gas introduction path to the mixed gas derivation path.
