1. A complex power generation facility comprising:
a first transfer unit that transfers liquefied natural gas;
a first heat exchange apparatus that causes the liquefied natural gas supplied from the first transfer unit to exchange heat with seawater, vaporizes the liquefied natural gas into natural gas, heats the seawater into hot water, and discharges the hot water;
a second heat exchange apparatus that selectively receives the hot water discharged from the first heat exchange apparatus and causes the natural gas passing through the first heat exchange apparatus to exchange heat with seawater and hot water;
a power generation unit that generates power as the natural gas supplied from the second heat exchange apparatus passes therethrough;
a second transfer unit that transfers the natural gas discharged from the first heat exchange apparatus to the second heat exchange apparatus; and
a third transfer unit that transfers the natural gas discharged from the second heat exchange apparatus to the power generation unit,
wherein the first transfer unit includes:
a first transfer line;
a first pressurization line connected to the first transfer line in parallel and provided with the first pressurization means for pressurizing liquefied natural gas; and
a first switching valve that is installed at inlets of the first transfer line and the first pressurization line and selectively supplies received liquefied natural gas to any one of the first transfer line and the first pressurization line,
wherein the second transfer unit includes:
a second transfer line;
a second pressurization line connected to the second transfer line in parallel and provided with the second pressurization means for pressurizing natural gas; and
a second switching valve that is installed at inlets of the second transfer line and the second pressurization line and selectively supplies received liquefied natural gas to any one of the second transfer line and the second pressurization line,
wherein the third transfer unit includes:
a third transfer line;
a third pressurization line connected to the third transfer line in parallel and provided with the third pressurization means for pressurizing natural gas; and
a third switching valve that is installed at inlets of the third transfer line and the third pressurization line and selectively supplies received liquefied natural gas to any one of the third transfer line and the third pressurization line.
