ABSTRACT:
A vaporizer for liquefied natural gas which prevents the heat exchanger tubes from being extremely cooled, without reducing the vaporizing efficiency. The vaporizer is characterized in that each of the heat exchanger tubes connecting the lower header and upper header contains a pipe for liquefied natural gas in a certain region from its end near the inlet, said pipe having on its outer surface fins which are in pressure contact with the inner surface of the heat exchanger tube, and the heat exchanger tube is in direct contact with the natural gas in its region near the outlet and beyond the region in which the pipe for liquefied natural gas lies.
