Abstract

In a liquid vaporizing/feeding method of the present invention, carrier gas is forced out at a very high speed against a mass flow controlled liquid feedstock to change the liquid feedstock into a mist; after that, the mist of the feedstock is vaporized and mixed with the carrier gas, and a mixture of the mist and carrier gas is furnished to a succeeding process. A liquid vaporizer/feeder according to the present invention comprises a main vaporized unit which is cylindrical in shape, and a mist nozzle having an inside nozzle fixed in an inlet of the main vaporizer unit for feeding liquid feedstock into the main vaporizer unit and an outside nozzle encompassing an opening of the inside nozzle for forcing a carrier gas at high speed around the opening of the inside nozzle, and the main vaporizer unit has an evaporation space where a mixed mist of the liquid feedstock with the carrier gas that is forced out of the mist nozzle is vaporized.
