摘要： 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.

摘要： Disclosed herein is a method of firing a gas turbine with LNG which is designed to store the "cold" of LNG in an the LNG vaporizer. The method comprises supplying liquefied natural gas through heat exchanger tubes in the LNG vaporizer, thereby gasifying the liquefied natural gas by heat exchange with a heat transfer medium recycled through the LNG vaporizer and an air precooler, and cooling the air in the air precooler by heat exchange with the heat transfer medium cooled by the liquefied natural gas when the turbine load is high, and suspending the recycling of the heat transfer medium through the LNG vaporizer and air precooler, thereby causing the heat transfer medium to freeze on the outside of the heat exchanger tubes (for the storing of freezing latent heat) by the "cold" of the liquefied natural gas supplied, when the turbine load is low, and using the freezing latent heat (stored by the freezing of the heat transfer medium) as a "cold" source to cool air through the heat transfer medium, when the turbine load is high.
