Engine waste heat recovering apparatus
An engine cooling unit and an exhaust gas heat exchanger 9 for use with the exhaust gas from an engine are connected with a circulation path 12 for circulating a heat transfer medium. The output of the circulation path 12 is connected via a conduit 18 to an output heat exchanger installed in e.g. a...

| description | An engine cooling unit and an exhaust gas heat exchanger 9 for use with the exhaust gas from an engine are connected with a circulation path 12 for circulating a heat transfer medium. The output of the circulation path 12 is connected via a conduit 18 to an output heat exchanger installed in e.g. a hot water storage tank 17. The exhaust gas heat exchanger 9 is disposed across the circulation path 12 at the upstream side of the engine cooling unit of the engine 2. The heat transfer medium introduced into the exhaust gas heat exchanger 9 is set to a lower temperature enough to maintain the temperature of vapor in the exhaust gas of which heat is transferred to the heat transfer medium lower than the dew point. The heat transfer medium after drawing generic heat from the exhaust gas and receiving its condensation heat in the exhaust gas heat exchanger 9 is passed to the engine cooling unit 6A where it draws more heat. Accordingly, the heat generated by the engine 2 can be recovered at a higher efficiency. |
