The context of the researchThe UK has set a target to cut its greenhouse gas emissions by at least 80% by 2050, relative to 1990 levels. To achieve this target, a reduction in energy consumption of around 40% will be required, and therefore significant improvements in energy efficiency are necessary. Energy recovery from industrial waste heat sources is considered to offer a significant contribution to improving overall energy efficiency in the energy-intensive industrial sectors. Brief description of the context of the research including potential impact;Although there are several alternative technologies for waste heat recovery, the ORC system remains the most promising in practice. Large ORC systems are commercially viable for high-temperature applications (e.g. Ormat, USA) however, the application to low-temperature waste heat (<250 centigrade ) is in its infancy. Yet more than 60% of UK industrial waste heat sources are in the low temperature band (<250 centrigrade). There is clearly a mismatch between ORC technology supply and demand, so innovative research and development for develop efficient small scale ORC power plants are highly required.Aims and objectives;Increase the understanding of Organic Rankine Cycle power plants using zeotropic mixture of refrigerants as the working fluid.Investigate how the system performance can be improved in response to the changing heat source and heat sink temperature.Novelty of the research methodology;Dynamic modelling method The utilization of zeotropic mixture as working fluidAlignment to EPSRC's strategies and research areas;The research theme of Energy will be addressed through the research area of Energy Efficiency (end use energy demand) which is the largest area highlighted for growth under this theme. Energy Efficiency is also a growing research area under the research theme Engineering. This project aligns closely with EPSRC's strategy on the energy theme and will address this challenge by developing a more efficient and flexible waste heat recovery system.Its potential applications and benefits;The developed technology can be widely applied for industrial waste heat recovery, and distributed power generation from biomass. The wide installation of this technology can reduce greenhouse gas emissions and improve energy security.Any companies or collaborators involved;DRD Power Ltd and Wellman Thermal Technology

研究背景英国设定了到 2050 年温室气体排放量相对 1990 年水平至少减少 80% 的目标。为了实现这一目标，需要减少40%左右的能源消耗，因此需要大幅提高能源效率。工业废热源的能量回收被认为对提高能源密集型工业部门的整体能源效率做出了重大贡献。简要描述研究背景​​，包括潜在影响；尽管有多种余热回收替代技术，但 ORC 系统在实践中仍然是最有前途的。大型 ORC 系统在高温应用方面具有商业可行性（例如美国 Ormat），但在低温废热（<250 摄氏度）方面的应用尚处于起步阶段。然而，超过 60% 的英国工业废热源处于低温带（<250 摄氏度）。 ORC技术供需之间显然存在不匹配，因此迫切需要创新研发来开发高效的小型ORC发电厂。目的和目标；增加对使用非共沸制冷剂混合物作为工作介质的有机朗肯循环发电厂的了解研究如何提高系统性能以响应不断变化的热源和散热器温度。研究方法的新颖性；动态建模方法利用非共沸混合物作为工作流体对准EPSRC的战略和研究领域；能源研究主题将通过能源效率（最终用途能源需求）研究领域来解决，这是该主题下强调增长的最大领域。能源效率也是工程研究主题下不断发展的研究领域。该项目与EPSRC关于能源主题的战略紧密结合，将通过开发更高效、更灵活的余热回收系统来应对这一挑战。其潜在应用和效益；所开发的技术可广泛应用于工业余热回收和分布式发电生物质发电。该技术的广泛安装可以减少温室气体排放并提高能源安全。任何参与的公司或合作者；DRD Power Ltd 和 Wellman Thermal Technology
