<p>PURPOSE:To contrive to micrify bubbles flowing out of the jetting part of liquefied gas so as to prevent the heat-exchanging ability of the evaporator from lowering by a method wherein a discharge nozzle of liquefied gas is enclosed with a cover with an open lower end shaped in ziazag. CONSTITUTION:For the liquefied gas evaporator 1 which gasified liquefied gas by directly contacting with a heating medium such as sea water, fresh water or the like, the discharge nozzle 3 of the liquefied gas is enclosed with the cover 4 with the open lower end. The lower end of the cover 4 is located below the liquid surface of the heating medium and the gas-liquid boundary surface 5, which is held by the pressure of evaporated gas, is provided at the lower end 17 shaped in zigzag 19 of said cover 4. Accordingly, no large lump of bubble is generated from the jetting part of liquefied gas, resulting in enabling to obtain the liquefied gas evaporator with excellent heat-exchanging ability.</p> |
