Abstract
To provide a method and an apparatus for feeding a zinc gas superheated to a boiling point of zinc or higher at a controlled rate of feed. The method for feeding the zinc gas according to the invention includes a step for introducing melt zinc into a zinc gas evaporation apparatus, a step for generating the zinc gas from the melt zinc by inputting electric power corresponding to a rate of feed of the zinc gas to allow zinc to cause self-heating by high-frequency induction heating, a step for introducing the generated zinc gas into a gas heating apparatus, and a step for heating the zinc gas by resistance heating to form a superheated zinc gas. An apparatus for feeding the zinc gas according to the invention is applied to the method, and includes a zinc gas evaporation apparatus, a gas heating apparatus and a control apparatus.
