| 摘要 |
The present invention relates to an arrangement for recovery of thermal energy from exhaust gases arising from a supercharged combustion engine. The arrangement comprises an exhaust line (3) adapted to leading exhaust gases out from the combustion engine (1), a turbine (4) driven by the exhaust gases in the exhaust line (3), at least a first EGR system which has a first return line (8) for recirculation of exhaust gases from a point (3b 1 ) situated downstream of the turbine (4) with respect to the intended direction of flow of the exhaust gases in the exhaust line (3), and a WHR system which comprises a closed line circuit with a circulating medium, at least a first evaporator (12) in which the medium is warmed and vaporised. Said first evaporator (12) is configured as a composite unit in which the circulating medium is caused to absorb thermal energy both from the recirculating exhaust gases in the first return line (8) and from exhaust gases in a section of the exhaust line (3b) downstream of the point (3b 1 ) in the exhaust line where the first return line (8) receives exhaust gases from the exhaust line (3). |
