PURPOSE:To improve the heat exchanging efficiency of a condenser by ejecting the gas, within a liquefied gas storage tank, to the heat conducting surface of a condenser through nozzles and by returning the condensed liquid into the storage tank. CONSTITUTION:A pressure reducing device 11, with its condenser being formed by a jacket 14 and the side wall of an outer cylinder 12, is installed on the top of a liquefied gas storage tank 1, nozzles 18 are provided on the inner cylinder 13 of the pressure reducing device 11, and the inner cylinder 13 is connected to the top of the liquefied gas storage tank 1 with a connecting pipe 17. The gas within the liquefied gas storage tank 1 is ejected to the heating surface of the condenser through nozzles 18 for condensing, and the condensed liquid is returned into the liquefied gas storage tank 1 through a reflux mechanism 31. Hereby, the gas side boundary film at the heating surface can be removed, resulting in the improvement of the condenser heat exchanging efficiency. |
