<p>PURPOSE:To readily obtain an air-mixed liquefied gas exhibiting a stable quantity of heat, by mixing a gas obtd. by evaporating a liquefied gas with a cooling medium for air dehumidification, followed by complete gasification, with an air dehumidified with the aforesaid cooling medium. CONSTITUTION:An apparatus comprising a liquefied gas storage tank (1), an evaporator in which a low-temp. liquefied gas fed from the storage tank (1) and having a pressure reduced by means of a liq. pressure regulating valve (3) is evaporated by heat exchange with a cooling medium, an air dehumidifier (18) in which a cooling pipe (17) through which the cooling medium cooled by means of the evaporator (4) is circulated is inserted and air (introduced through an opening 16) is cooled to be dehumidified, and a mixer (13) in which the liquefied gas (12) fed from the evaporator (4) and passed through a vaporizer (7) (e.g., vaporizing with hot water supplied from a hot water producer 8) and a gas pressure regulating valve (11) is mixed with the air fed from the air dehumidifier (18) and having a regulated pressure (21).</p> |
