6 Conclusion and Outlook

An exhaust evaporator has been developed for Rankine Cycle Waste Heat recovery applications. It is based on a modular and robust concept and can be operated at high pressure up to 60 bar. Design and production have been certified. Test setups have been developed for component testing and system integration testing. Evaporator units have seen in-field operation since 2007 and proved very durable.

For a broad application of (Organic) Rankine Cycle Waste Heat Recovery it is important that the system efficiency and investment together result in an accept- able earn back period. The efficiency needs to be optimised through a systems engineering approach that can be supported through developed simulation models. The system cost should be optimized through cost-effective production and system integration. The latter could for instance be accomplished through integration of exhaust gas aftertreatment and evaporator. Future work on the evaporator design will focus on further improvement of long-term endurance through study of potential pulsive flow with simulation methods.

摘要：一种能够应用于朗肯循环中的高温换热器现在已经被制造出来。对于大功率高消耗的交通工具以及生产设备来说，需要进行余热处理，而朗肯系统技术就是用来处理预热的。这种高温换热器是组合式的并且有一个一个稳定的设备构造，它能够在高温和一定的压力范围下工作。这种换热器在实验中已经证实了它的性能。并且符合欧洲压力容器条例和德国AD2000。在实际的工作中，这种换热器连续工作2007个小时都没有故障。模块化设计需要制定专用换热器。这个过程需要选择一个稳定的尺寸工具和仿真模型。
