This heat recovering apparatus for a cogeneration system with an engine comprises a turbocharger driven by an exhaust gas, an energy recovering turbine provided on the downstream side of the turbocharger, and a heat exchanger provided on the downstream side of the energy recovering turbine. The energy recovering turbine comprises a gas turbine driven by an exhaust gas, and a steam turbine driven by steam occurring in the heat exchanger. The heat exchanger comprises a casing joined to an exhaust gas passage, oxidation resisting ceramic pipes, in which the water and steam flow, provided in the casing, and oxidation resisting ceramic porous members, through which an exhaust gas can pass, provided in the portions of the interior of the casing which are on the outer sides of the ceramic pipes.
