摘要
An apparatus and method for increasing efficiency of a gas turbine and a marine structure having the gas turbine are disclosed. The marine structure includes an ambient LNG vaporizer for regasifying cryogenic LNG via heat exchange with air and the gas turbine for generating electric power. The marine structure includes a moist-air mixing chamber disposed at an upstream side of the gas turbine, a condensed-water nozzle to spray condensed water, generated from air during the heat exchange in the LNG vaporizer, into the moist-air mixing chamber; and a cold air supply pipe to supply air, cooled by the heat exchange in the LNG vaporizer, to the gas turbine via the moist-air mixing chamber. The method reduces the temperature of air supplied to the gas turbine by condensed water or cold air generated during regasification of LNG through the ambient vaporizer in the marine structure, thereby increasing the efficiency of the gas turbine.
