Abstract
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.
