<p>PURPOSE:To prevent condensate liquid from overcooling to improve heating-vaporizing efficiency of intermediate thermal medium by heating and vaporizing liquefied natural gas with the intermediate thermal medium and providing filler at a contact portion between condensate liquid drops of the gas and a vaporizer. CONSTITUTION:Filler 5 is disposed in the center of a drum at the boundary between a carbureter 3 for LNG and a vaporizer 4 for liquefied propane gas outside pipe. Thus, LNG is introduced into the carbureter 3 to be heated and vaporized by PG outside pipe, introduced from a line 13 to the outside of the pipe of a heater 11, heated by seawater in the pipe and taken out of a line 14 to the outside of system. On the other hand, the seawater introduced from an end chamber 16 heats and vaporizes LPG in the pipe with the vaporizer 4, and is taken out of a line 17 to the outside of system. LPG condensated outside the pipe of the carbureter 3 is attached to the filler 5 as it drops and contacts PG ascending to have temperature for approximately saturating pressure in the drum. Thus the condensated LPG is prevented from overcooling to improve heating efficiency of a intermediate thermal medium.</p> |
