摘要： The quatro generation system of the present invention includes: a power generation engine driven by fuel gas; an exhaust-heat boiler configured to utilize energy of exhaust gas discharged from the power generation engine to produce steam from boiler water; a boiler-water circulation device configured to supply the steam produced by the exhaust-heat boiler to a steam-energy recovery unit, and to return condensed water of the steam to the exhaust-heat boiler after the steam-energy recovery unit recovers energy of the steam; a condensation economizer configured to utilize condensation latent heat of exhaust gas discharged from the exhaust-heat boiler to heat a heat medium; and a heat-medium circulation device configured to supply the heat medium heated by the condensation economizer to a thermal-energy recovery unit, and to return the heat medium to the condensation economizer after the thermal-energy recovery unit recovers energy of the heat medium.
