Due to the low boiling point of organic fluids, the organic Rankine cycle (ORC) is an effective way to improve the recovery efficiency of low-temperature waste heat. An ORC power plant was established with an actual generating capacity of 16.3 kW. As the ORC technology is in the initial stage of commercial application, a technical and economic analysis has been conducted in this paper. Through analysis of each part investment of the power generation plant, it is found that the ORC system part accounts for 61% of the total initial investment, and the larger the power generation scale, the larger the proportion. An economic model has been proposed to study the economic feasibility of low-temperature industrial waste heat conversion in this plant. The influences of the installation of cooling water system, preheater, superheater, loan ratio, interest rate on electricity production cost (EPC) and profit are analyzed. According to the analysis, the lowest EPC of the plant is 0.46 Yuan/(kW • h).

具有低温余热回收的ORC电厂的实验经济分析

由于有机流体的低沸点，有机朗肯循环（ORC）是提高低温废热回收效率的有效途径。建立了ORC电厂，实际发电量为16.3 kW。由于ORC技术处于商业应用的初期，因此本文进行了技术和经济分析。通过对发电厂各部分投资的分析，发现ORC系统部分占初始投资总额的61％，发电规模越大，所占比例越大。已经提出了一种经济模型来研究该工厂中低温工业废热转化的经济可行性。冷却水系统，预热器，过热器，贷款比例的安装的影响，分析了电力生产成本（EPC）和利润率。根据分析，该厂的最低EPC为0.46元/（kW•h）。
