本文通过介绍一种最先进的实验设备来研究中试热交换器和处理高温废热回收和转换的装置，解决了基础能源研究和工业开发技术之间的桥梁需要。该设施包括一个830 kW的工艺空气加热器，在70 mbar时排气质量流量为1.0 kg/s，最高温度为780 °C。该加热器有一个2.0米长的测试段，用于安装和表征废热回收热交换器。散热器是一个500千瓦的水干式冷却器，可完全控制冷却流的流速和温度。高温热电转换设施拥有一个50 kWe的电力转换装置，该装置基于简单的回热式焦耳-布雷顿循环，以超临界CO2（sCO 2）为工作流体。该封装的即插即用sCO 2系统采用单轴压缩机-发电机-涡轮机装置。本文讨论了测试设施的主要设计特点以及操作和安全考虑。
This paper addresses the need of bridging between fundamental energy research and industrial exploitation of technologies by presenting a state of the art experimental facility to investigate pilot heat exchangers and plants dealing with high temperature waste heat recovery and conversion. The facility comprises a 830 kW process air heater with an exhaust mass flow rate of 1.0 kg/s at 70 mbargand maximum temperature of 780 °C. The heater has a 2.0 m long test section for the installation and characterization of waste heat recovery heat exchangers. The heat sink is a 500 kW water dry cooler with full control of flow rate and temperature of the cooling stream. The high-temperature heat to power conversion facility hosts a 50 kWe power conversion unit based on the simple recuperated Joule-Brayton cycle with supercritical CO2(sCO2) as working fluid. The packaged, plug and play sCO2system utilizes a single-shaft Compressor-Generator-Turbine unit. The paper discusses the main design features of the test facility as well as operation and safety considerations.
