he vast volumes of waste heat rejected from industrial processes can be converted into electricity and useful heat through advanced energy conversation technologies. In this project, a test rig of a small-scale power generation (up to 5kW) and heat recovery system will be established with a heat source temperature between 100 ^C and 500 ^C, which is representative of actual industrial waste heat. The natural refrigerant CO2 will be engaged as a working fluid in the system, considering its excellent thermophysical properties and negligible environmental impact. Corresponding to the large temperature range of the heat source, the CO2 supercritical Rankine cycle will be applied for temperatures below 350 ^C, otherwise, combined CO2 Brayton and supercritical Rankine cycles will be employed. Simultaneously, a detailed mathematical model for the proposed system will be developed and validated with measurements. The model will then evaluate, compare and analyse different system and component designs, heat recovery potentials and control optimisations which will eventually lead to optimal design and construction of the proposed system.

通过高级能源对话技术，可以将大量因工业过程拒绝的废热被转换为电力和有用的热量。在这个项目中，将建立一个小型发电（最高5kW）和热恢复系统的测试钻机，并在100 ^c和500 ^C之间建立，这代表了实际的工业废料。天然制冷剂二氧化碳将在系统中作为一种工作流体，考虑到其出色的热物理特性和可忽略的环境影响。与热源的大温度范围相对应，将使用低于350 ^c的温度来应用二氧化碳超临界循环，否则将使用二氧化碳和超临界兰金周期组合。同时，将通过测量来开发和验证提出的系统的详细数学模型。然后，该模型将评估，比较和分析不同的系统和组件设计，热恢复电位和控制优化，最终将导致提出的系统的最佳设计和构建。
