エンジンの排気熱回収装置。The catalytic converter 3, the heat radiating part 5 and the muffler 6 of the heat exchange device 4 are connected in this order to the exhaust port 2 of the gas engine 1, and the heat recovery channel 8 is connected to the heat absorption part 7 of the heat exchange device 4. Exit 10 and exhaust gas inlet 1 of catalytic converter 3
A catalyst 15 for pre-combustion of unburned components in the exhaust gas is provided at a position 14 near the connection part 12 with the combustion chamber 16, so that the high-temperature exhaust gas in the combustion chamber 16 does not reach that temperature immediately after exiting to the exhaust port 2. Before it descends, it comes into contact with the pre-combustion catalyst 15,
Even if the temperature of the exhaust gas decreases by the time it reaches the catalyst 17 in the catalytic converter 3 after pre-combusting some of the unburned components in the exhaust gas to raise the temperature of the exhaust gas, the catalyst 17 is contacted at a sufficiently high reaction temperature to sufficiently burn unburned components, raising the temperature of the exhaust gas and increasing its retained heat amount, and this exhaust gas passes through the heat radiation section 5 of the heat exchange device 4. An exhaust heat recovery device for a gas engine, characterized in that a large amount of heat retained in the exhaust gas is absorbed and recovered by a heat medium passing through a heat absorption part 7 via a heat exchange device 4.
