Waste heat recovery system and waste heat recuperation process

摘要

The invention provides an improved Abwärmerekuperationssystem with heat storage and energy recovery device in which the heat accumulator and the energy recovery device can be applied independently with waste heat and by means of the heat storage equalization of the waste heat for the energy recovery device. The inventively advantageous Abwärmerekuperationssystem therefore comprises a heat storage and an energy recovery device in an exhaust system, the exhaust system is divided by a branch and a merge in a first exhaust manifold and a second exhaust manifold and in the first exhaust manifold of the heat storage by means of a first heat exchanger and the second exhaust line, the energy recovery device is integrated by means of a second heat exchanger. The heat storage and the energy recovery device are arranged parallel to each other and further coupled to each other by means of a third heat exchanger. The second heat exchanger and the third heat exchanger of the energy recovery device are designed such that they work at different temperature levels. Preferably, the third heat exchanger operates at a higher temperature level compared to the second heat exchanger.
