| description | In accordance with one aspect of the present invention, a combined power generation system includes: a gas turbine generating a rotating force by combusting fuel; an exhaust heat recovery boiler heating water by using combustion gas discharged from the gas turbine and provided with a high-pressure unit, a medium-pressure unit and a low-pressure unit having different pressure levels; a fuel preheater heating the fuel supplied to the gas turbine and provided with a primary heating unit and a secondary heating unit; a high-pressure water supply pipe connected to the high-pressure unit to supply high-pressure water to the secondary heating unit; a water delivery pipe connecting the secondary heating unit and the primary heating unit to supply the water discharged from the secondary heating unit to the primary heating unit; and a water supply control pipe connected to the medium-pressure unit to supply medium-pressure water to the water delivery pipe, wherein the water supplied to the secondary heating unit through the high-pressure water supply pipe is formed of liquid, and the phase of the water is unchangeable in the fuel preheater. Therefore, the present invention is capable of preventing an impact and vibrations from occurring due to a phase change in water.
