Procedure and arrangement for improving the utilization of exhaust gas heat energy in large diesel engines

摘要

Part of the heat energy contained in the exhaust gases of a large diesel engine (1) is recovered in a heat exchanger (5) before leading the exhaust gases into a turbocharger (3), and at least a major part of the recovered heat energy is used for producing secondary energy usable independently of the production of mechanical energy by the engine (1). The heat energy recovered can with advantage be utilized for hot water or steam production in a generator (6). A second heat exchanger (10) can be provided downstream of the turbocharger (3) and can be used to preheat water for the generator (6). IMAGE
