ジンの排熱回収装置。An exhaust gas heat exchanger 4 is connected to the exhaust manifold 3 of the engine 1 that drives the load 2, and the hot water supplied to the exhaust gas heat exchanger 4 and the exhaust gas flowing through the exhaust gas heat exchanger 4 are heat-exchanged. A catalyst 6 is installed on the exhaust gas inlet 4c side of the exhaust gas heat exchanger 4 to remove harmful substances from the exhaust gas, and a catalyst 6 is installed behind the catalyst 6 to detect 0□ in the exhaust gas. 02 detector 7 is provided,
The engine exhaust heat recovery device controls the fuel supply amount of the engine 1 so that the air-fuel ratio becomes the theoretical air-fuel ratio according to the value detected by the detector 7.
