Device for energy recovery for a large diesel engine

摘要

A device for energy recovery for a large diesel engine includes a current generator for converting mechanical rotational energy into electric energy. The current generator includes input shaft for applying rotational energy; a steam turbine a first shaft for transmitting the rotational energy of the steam turbine to the input shaft of the current generator a power turbine and a second shaft for transmitting the rotational energy of the power turbine to the input shaft of the current generator, wherein the first shaft and the second shaft are coupled with the input shaft of the current generator. A first coupling device between the current generator and the steam turbine couples the input shaft of the current generator and the first shaft and/or a second coupling device between the current generator and the power turbine couples the input shaft of the current generator and the second shaft are provided.
