A liquefied-gas vaporization system (1) is provided with: a liquefied-gas vaporization unit (2) in which a liquefied gas stored in a liquefied-gas tank is subjected to heat exchange with a heat medium, and vaporized; a boil-off-gas combustion unit (3) which induces combustion of a boil-off gas of the liquefied gas; a turbine (4) which is rotationally driven by the energy of a combustion gas obtained after combustion has been performed in the boil-off-gas combustion unit (3); and a combustion-gas supply unit (8) which supplies, as the heat medium, to the liquefied-gas vaporization unit (2), the combustion gas discharged from the turbine (4). The boil-off-gas combustion unit (3) is a pressurized combustion unit which has compressed air supplied thereto, and in which the boil-off gas is subjected to pressurized combustion. A compressor (5), which generates the compressed air and supplies the compressed air to the boil-off-gas combustion unit (3) as air for pressurized combustion, is provided on the same axis as that of the turbine (4).
