A furnace type cogeneration system is provided to reduce the amount of oxygen to be applied to a blower and power consumption for driving the blower by using the oxygen contained in the engine exhaust gas in burning of a fuel. A burner(50) is mounted on the front end of a combustion furnace(10), and provided with a fuel(40) and combustion air(30) so as to generate flame in the combustion furnace and heat an object(100). A combustion furnace type cogeneration system includes a combustion air supply pipe(31) and an engine exhaust gas supply pipe(91). The combustion air supply pipe is interposed between the burner and a blower(20), and supplies combustion air supplied from the blower to the burner. The engine exhaust gas supply pipe has one end connected to an exhaust gas outlet port of an engine(80) for driving a generator(70), and the other end added to a burner connection side of the combustion air supply pipe. The engine exhaust gas supply pipe supplies an engine exhaust gas(90) discharged from the engine to the combustion air supply pipe such that the engine exhaust gas is supplied to the burner together with the combustion air supplied from the blower.
