Power Generation and Heat Recovery from Industrial Waste Heat with Advanced CO2 Thermodynamic Power Cycles (PowerCO2)

在英国，每年大约有48 TWh/年的工业废热源，相当于整个工业能源使用的六分之一。在这些工业废热中，技术上有11 TWh/年（2.2 MtCO 2/年）可以通过专门设计的能源转换技术回收用于有用的目的，例如热电联产（CHP）。在全球范围内，三分之一的能源消耗可归因于工业部门，高达50%的能源最终被浪费为热量。因此，工业余热发电的市场十分巨大。该项目将为工业余热能源转换系统创造一种创新的CO2跨临界动力循环（iT-CO2）。该系统将开发并安装一台CO2跨临界压缩机和汽液喷射器，以取代不适用的CO2液体泵，从而实现30%的热电效率目标（即最先进水平的两倍）。该项目成果将针对钢铁、玻璃和其他需要热电联产解决方案的热密集型行业。

Each year in the UK, approximately there are 48 TWh/yr industrial waste heat sources which is equivalent to one sixth of overall industrial energy use. Of this amount of industrial waste heat, technically 11TWh/yr (2.2 MtCO2/yr) could be potentially recovered for useful purposes such as Combined Heat and Power (CHP) through specially designed energy conversion technologies. Globally one third of energy consumption is attributable to the industrial sector, with up to 50% ultimately wasted as heat. The market of power generation with industrial waste heat is thus enormous.The project will create an innovative CO2 transcritical power cycle (iT-CO2) for energy conversion systems with industrial waste heat. Instead of using an inapplicable CO2 liquid pump, a combined CO2 transcritical compressor and vapour-liquid ejector will be developed and installed in the system to create thermal-to-electrical efficiency of a target 30% (i.e. double state-of-the-art).The project outcomes will target heat-intensive industries such as steel, glass and other heat-intensive planets that require CHP solutions on sites or grid connections.
