本文对热电联产系统中的低温有机朗肯循环进行了热经济性分析。对于混合动力装置，热能输入由地热资源与沼气发动机的废气结合提供。通过考虑ORC工作流体、供热网络的供应温度或地热水温度等可变参数，与替代地热热电联产概念进行比较。第二定律效率以及经济参数表明，混合动力发电厂比传统的热电联产概念或单独使用的能源更有效。
We present a thermo-economic analysis for a low-temperature Organic Rankine Cycle (ORC) in a combined heat and power generation (CHP) case. For the hybrid power plant, thermal energy input is provided by a geothermal resource coupled with the exhaust gases of a biogas engine. A comparison to alternative geothermal CHP concepts is performed by considering variable parameters like ORC working fluid, supply temperature of the heating network or geothermal water temperature. Second law efficiency as well as economic parameters show that hybrid power plants are more efficient compared to conventional CHP concepts or separate use of the energy sources.
